[[File:Gameboy-glacier.jpg|thumb|The Gameboy Advance handheld console]]The '''[[gametech:Game Boy Advance|Game Boy Advance]]''' (often shortened to GBA) is a 32-bit handheld video game console developed by Nintendo. It is the successor to the Game Boy Color. It was released in Japan on March 21, 2001; in North America on June 11, 2001; in Australia and Europe on June 22, 2001.

The '''[[wikipedia:Xbox (console)|Xbox]]''' is a sixth-generation console released by Microsoft on November 15, 2001. Known as the DirectXbox during development, it is notable for the specs having similarities to a PC, namely as a result of using familiar components around the [[wikipedia:x86|x86]] architecture. It had a custom Pentium III CPU at 733 MHz with 64 MB of RAM, and a custom Nvidia GPU codenamed NV2A at 233 MHz. The Xbox was often said to be the most powerful console from the sixth generation, and Sega later designed the '''[https://segaretro.org/Sega_Chihiro Chihiro arcade system]''' with the same components. It retailed at {{inflation|USD|299.99|2001}}.
 +
 
 +
The Xbox was a modest seller, and helped create a brand for Microsoft that would give [[Xbox 360 emulators|its successor]] a stronger market share in the west; despite Microsoft's best efforts the original Xbox and succeeding consoles from the company have never gained a foothold in Japan for various reasons.<ref name="Censored_Gaming">{{cite web|url=https://youtu.be/DmCHJmi_st4|title=Why The Xbox Failed In Japan|publisher=Youtube|accessdate=2018-07-25|date=2018-07-16}}</ref> It had a number of advantages over other sixth-gen consoles at the time; it was the only console to include a hard disk,<ref group=N>The [[PlayStation 2 emulators|PlayStation 2]] also had a hard disk accessory, but the Xbox had it built-in on all models.

Early in its lifespan, the Xbox had [[wikipedia:Xbox modding|an unusually active modding scene]] compared to the other consoles (often vindicated by the incredibly short warranty). Upon the first jailbreak by [[wikipedia:Andrew Huang (hacker)|Andrew Huang]], the scene ultimately delivered no comprehensive emulation until the mid-2010s,<ref group=N>The Xbox would have been too difficult to emulate at the time anyway as its specs often rivaled that of consumer PCs, and it was alleged that many developers received legal threats from Microsoft to dissuade them from trying.</ref> where developers have continued to have issues owing to the fact that, alongside the poorly documented hardware, many of the Xbox's games either came from Windows or were then released for Windows afterward (though it does retain a few exclusives). However, the Xbox emulation scene has been resurging with two emulators at the forefront since mid-2017. Its developers continue to say there's no competition between them, as they're both open-source and have different goals and methods.<ref>[https://www.reddit.com/r/emulation/comments/8ymp6n/cxbxreloaded_just_hit_v01/e2ckmpl/ JayFoxRox's statement] (representing XQEMU).

===Comparisons===
* [[gpSP]] last official version was 0.9 by Exophase. There are, however, two superior forks: [http://dl.qj.net/psp/emulators/gpsp-mod-20090720.html gpSPmod] and [http://filetrip.net/psp-downloads/homebrew/download-gpsp-j-12-06-16-f29570.htmlgpSP-J gpSP-J]. gpSP-J has superior compatibility, while gpSPmod has more options for customization (full screen, cheats, etc). Both are superior to Kai.

Since May 2017, serious strides have been happening in the Xbox emulation scene with Cxbx-Reloaded and XQEMU making major progress. Cxbx-Reloaded went in-game for ''Jet Set Radio Future'' with a somewhat decent framerate.<ref name="Bahax Emulation">{{cite web|url=https://www.youtube.com/watch?v=K_5dIUPs0_I|title=Cxbx Reloaded - JSRF(Semi-Playable/35~60 FPS)|publisher=Youtube|accessdate=2018-05-11|date=2017-05-10}}</ref> Many more original Xbox games have been able to get in-game and, in some cases, at decent speeds on XQEMU.<ref name="Reddit">{{cite web|url=https://www.reddit.com/r/emulation/comments/6c93rg/xqemu_more_games_ingame/dhuakqc/|title=XQEMU - more games ingame|publisher=Reddit|accessdate=2017-06-11|date=2017-05-23}}</ref><ref name="JGG_3">{{cite web|url=https://m.youtube.com/watch?v=J20hlsOUFq0 |title=XQEMU Xbox Emulator - MechAssault Ingame! |publisher=Youtube|accessdate=2018-06-23|date=2018-06-22}}</ref>
* [[Visual Boy Advance -M|Visual Boy Advance-M (VBA-M)]] is a fork of VBA with additional improvements. RetroArch's VBA-Next is based off an older revision of VBA-M with added speedhacks and tweaks, making it a bit less accurate in some respects, though it fixes a few games such as Advance Wars 2.
 
* [[higan]]'s GBA core is cycle-accurate, but is otherwise very much a WIP and not as compatible as either version of VBA.
 
* [[mGBA]] is a GBA emulator that aims to be accurate while maintaining speed. It's actively developed and has features that VBA-M lacks such as Solar/Tilt Sensor.
 
  
==Emulation issues==

 +
;[[xemu]]: A low-level emulator by Matt Borgerson continuing much of the work done on [[XQEMU]]. Focuses on stability, performance, and ease of use. 600+ games are reported playable, See the [https://xemu.app official game compatibility list].
 +
;[[Cxbx-Reloaded]]:A fork of [[Cxbx]] that's been having a good development momentum since mid-2016. It's built for x86_64 machines and includes a ton of improvements to its [[High/Low_level_emulation|HLE]] kernel, some from code originating in Dxbx and other related forks. While it has HLE support for the GPU and other parts (eg. audio) to make many games run fast, [https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/pull/1018 XQEMU's LLE implementation was introduced] in April 2018 and is expected to help even further. 150+ games are playable and 450+ games ingame. See [https://github.com/Cxbx-Reloaded/game-compatibility/issues this compatibility list] for more information.
 +
;[[XQEMU]]: A low-level emulator based on [[QEMU]]. It can emulate the BIOS and many games at very slow speeds but is sometimes faster than Cxbx with acceptable graphics. Audio has not been tested but has been assumed to be emulated, just not forwarded to the audio hardware for some reason. See [http://xboxdevwiki.net/XQEMU this compatibility list] that was taken from John GodGames' 2015 list, and [https://docs.google.com/spreadsheets/d/1sVtQ9SNPathKAMCqfYtvJQP0bs0UeLzP9otPHvZDMwE/htmlview#gid=709879345 this Google spreadsheet].
 +
;[[StrikeBox]]: Beginning low-level emulator that just initializes an x86 system and runs whatever is in the ROM. Not much works for this currently. It was uploaded to GitHub on [https://github.com/StrikerX3/OpenXBOX/commit/16013a6529eec37e997cd0ad1d5495cb83456014 Dec 5, 2017] by mborgerson, a well-known XQEMU contributor who in early 2018 is still focused on streamlining XQEMU's QEMU codebase. So expect more progress from XQEMU than StrikeBox in the meantime.
 +
;[[Cxbx]]: One of the first Xbox emulators, started as an ahead-of-time compiler for Xbox executables. Can boot around 56 games, with around a dozen in an already playable state. See [http://shogun3d-cxbx.blogspot.com/2009/11/cxbx-compatibility-list-updated.html this compatibility list].
 +
:;Dxbx: A port of Cxbx to Delphi, expanded with a redesigned symbol detection engine, and many rendering improvements, a new pixel shader converter, etc.
 +
;Xeon: Can emulate Halo CE to the point where the first stage is semi-playable. The walls and ground are pitch black, and the game crashes after you complete the first stage or right after you select the difficulty on modern versions of Windows.
 +
;[[MAME]]: Existing x86 emulation in MAME has given way to an <code>xbox</code> driver... that they've marked overall as <span style="color:darkred">not working</span> and sound as unimplemented (graphics are OK though).

;[[FU|Fusion]]:The internal name for backwards compatibility on the [[Xbox 360 emulators|Xbox 360]]. It supports [[wikipedia:List_of_Xbox_games_compatible_with_Xbox_360|a specific list of games]] that, while some work right off the bat, may need additional patches to play properly. It also requires your console to have system storage. Some games still have issues with graphical glitches and slowdowns to errors that can make standard gameplay basically impossible. There is more information and references/video(s) about this BC support [http://xboxdevwiki.net/Xbox_360_Backward_Compatibility#References_and_links here].
The original GBA screen was not backlit, which would render the screen rather dark. To compensate for this, games would be overly saturated. The bright overly saturated colors would appear rather normal on the GBA. In emulation however, this over saturation is not needed. Some games made after 2003 may look better with the backlit colors, however, as they were designed with the GBA SP in mind. For everything else, there are several ways to deal with this:

The Xbox is infamous in the emulation scene for being the worst case of false advertising. For the projects currently available and active there's a high barrier to entry for the effort involved, and it's the same reason why consoles using off-the-shelf hardware (or reused hardware) are easier to emulate. To users, being "basically a PC" and "x86-based" is a selling point despite that not being the case as the Xbox has a number of proprietary elements that are nothing like standard PC hardware (like the eighth-gen "x86-based" consoles). Many aspects of the Xbox's architecture aren't openly documented, making it a major pain to have to figure it all out.<ref name="ngemu">{{cite web|url=http://ngemu.com/threads/why-is-xbox-emulation-premature.132032/|title=Why is XBOX emulation premature?|publisher=ngemu|accessdate=2017-05-22|date=2010-02-15}}</ref><ref name="Microsoft1">{{cite web|url=https://msdn.microsoft.com/en-us/library/xbf3tbeh(v=vs.140).aspx|title=/LTCG (Link-time Code Generation)|publisher=Microsoft|accessdate=2017-05-22}}</ref><ref name="Microsoft2">{{cite web|url=https://msdn.microsoft.com/en-us/library/bb985904.aspx|title=Under The Hood: Link-time Code Generation|publisher=Microsoft|accessdate=2017-05-22}}</ref><ref name="FrameRater">{{cite web|url=https://www.youtube.com/watch?v=97mQcus7wFI|title=Xbox Emulation: The History & Roadblocks | A Documentary by FrameRater|publisher=Youtube|accessdate=2018-03-13|date=2018-03-08}}</ref><ref>{{cite web|url=https://www.reddit.com/r/emulation/comments/6dl94y/why_is_there_a_lack_of_original_xbox_emulation/|title=Why is there a lack of Original Xbox emulation?|publisher=Reddit|accessdate=2017-06-11|date=2017-05-29}}</ref> For example the APU, one of two sound processors on the [http://xboxdevwiki.net/MCPX MCPX southbridge chip] of the Xbox chipset, is [https://github.com/JayFoxRox/xqemu-espes/pull/24 incredibly powerful and uses complex processing steps] that are difficult to figure out using clean-room reverse engineering.
 
 
- GBA (no backlight) = strong desaturization
 
 
 
- GBA SP (backlight) = strong desaturization
 
 
 
- Nintendo DS in GBA mode = some desaturization
 
 
 
- VGA Mode (poppy bright): zero desaturization
 
 
 
'''VBA-M'''
 
 
 
- (VBA-M for Windows only) Under "Options->Gameboy" you will find the options:
 
 
 
- "Real Colors": no desaturization
 
 
 
- "Gameboy Colors": strong desaturization 
 
 
 
'''Shaders'''
 
 
 
[https://github.com/libretro/common-shaders/blob/master/cgp/gameboy-colors.cgp gameboy-colors.cgp]
 
 
 
A .cgp shader preset can be loaded in [[OpenEMU]] or [[RetroArch]] that is meant to (sort-of) replicate the "Gameboy Colors" option in VBA-M using the image-adjustment Cg shader. The settings are parameters that are stored in the cgp and can be adjusted at runtime. The relevant parameters set for this effect are:
 
 
 
Target Gamma = 2.4
 
 
 
Monitor Gamma = 2.16
 
 
 
Saturation = 0.5
 
 
 
Luminance = 0.9
 
 
 
The colors will not be exactly the same as what VBA-M produces (a bit brighter and no washed out blacks) but it will get you the desaturation effect. Can be adjusted to fit your tastes, and you can get the washed out blacks by increasing "Brightness Boost" and decreasing Luminance a bit.
 
 
 
More recently, a different [https://github.com/Monroe88/common-shaders/tree/color-lcd/handheld/color-lcd shader] using a lookup table was created to much more accurately simulate VBA and No$GBA's options.
 
 
 
===Save file issues===
 
There are a number of different save formats for GBA games. With raw save data, it's very hard to detect what save type it is just by looking at it. Visual Boy Advance tries to autodetect save type but often is incorrect and this causes issues. A fix to this issue is to use a file called "vba-over.ini" to tell VBA what each game's proper save type is, which eliminates most issues regarding save type. Current VBA-M versions come with vba-over.ini by default, but older versions of VBA like VBA 1.7.2 and VBALink did not.
 
 
 
The libretro versions of VBA, libretro-VBA-Next and libretro-VBA-M, come with vba-over.ini baked into the binary so it is able to load raw .sav files, but also changes the save file output to be a 136KB .srm file for every save type, with save type info contained within the file. This completely avoids any save type issues, but makes its save files incompatible with standalone VBA and most other emulators.
 
 
 
Libretro devs created a
 
[https://github.com/libretro/vbam-libretro/blob/master/src/libretro/gbaconv/gbaconv.c command line tool] to convert libretro-VBA .srm save files to raw .sav save data for other emulators. You can just drag and drop a .srm onto the executable and it will output raw .sav. The same can be done in reverse. A precompiled Windows 64-bit binary of this tool can be found
 
[https://www.mediafire.com/?6bg8ag0bjs1b7ng here].
 
 
 
==Connectivity==
 
===GBA Link Multiplayer (1~4GBA)===
 
* VBA-M: This doesn't work with old VBA versions.
 
 
 
Just disable "Pause when Inactive", configure all four Joypads each with their own button layout, enable "Link, Enable GBA Link". Now open VBA-M again as much times needed for each player, and have them each use their separate Joypad configuration. Each player will have a separate SRAM save file.
 
 
 
* VBA Link + e-Reader
 
A combined version of VBA Link and VBA e-Reader is useful if you want to use the Pokémon Battle-e Cards. Downloads and instructions reside [http://projectpokemon.org/forums/showthread.php?42433-RELEASE-VBA-LINK-E-READER here].
 
 
 
* No$GBA: This method also works with DS roms, and that's the actual way to see the incomplete non-functional local Wi-Fi DS multiplayer implementation. (todo)
 
 
 
===GameCube Connectivity===
 
The GBA unit can connect to a GameCube.
 
 
 
====Dolphin and VBA-M====
 
 
 
Game Boy connection support can be supported via joybus emulation. Such requires VBA-M (r947 or newer) and a dump of a GBA BIOS.
 
 
 
'''Connect 1~4 GBA Unit Without Game to GC Game'''
 
 
 
First Part!
 
* Open Dolphin and VBA-M. Make sure neither are blocked by your firmware.
 
* '''Dolphin:''' Start your game and play until you get to the in-game menu where you're asked to connect a GBA. Under the GC controller options (earlier "Config, Gamecube", now it's with the GC/Wii controller options). You have 4 GC controller ports: change how much you need to "GBA". Leave the game and its music running :)
 
* '''VBA-M:''' You'll need to uncheck "Options, Emulator, Pause When Inactive". Then, under "Options, Link, Joybus Options", Make sure to enable "Enable Joybus Connection" and set "IP/Hostname" to use default settings, that is (127.0.0.1) or (localhost) - without the brackets.
 
* THEN, Dolphin will freeze. You'll want to not have the system sound too high if you're using headphones.
 
 
 
Second Part!
 
* '''VBA-M''': Open the GBA BIOS in VBA-M as if it were a regular GBA ROM. There will be that splash screen but it will stutter a bit.
 
* Dolphin should recognize the Joybus Link by then and the GC game will detect that a GBA unit was connected.
 
* To connect other GBA units, open another VBA-M instance and repeat what you did with VBA-M.
 
 
 
Notable games that work:
 
* The Legend of Zelda Four Swords Adventures: Both two modes available for the US/PAL version work. The third Japan-only Navi Trackers mode works as well, but the game crashes after the naming screen due to a bug in the GC/GBA connectivity.
 
* Final Fantasy Crystal Chronicles
 
* Billy Hatcher: You can download games to your GBA. Amusingly, a RAM dump from VBA-M can be opened as a functional GBA ROM.
 
* Kururin Squash
 
* Sonic Adventure 2 (buggy)
 
 
 
Don't work:
 
* The Legend of Zelda Wind Waker: Tingle Trainer connection always fails, though some messages do display on VBA-M.
 
* Drill Land
 
* Any Pokémon game
 
* lots more
 
 
 
'''Connect GBA Game to GC Game'''
 
 
 
* '''VBA-M''': Under "Emulator, Bios Files" set the GBA BIOS file directory, and have the emulator use it. This will cause each regular GBA rom you load in VBA-M to show the BIOS splash screen then proceed to the game. It has higher compatibility too.
 
* You do the all the steps above in the '''first part''' of the previous section (connecting a GBA unit without Game to a GC game) until the line with Dolphin freezing when you enable Joylink in VBA-M.
 
 
 
Then:
 
* '''VBA-M''': Open the regular GBA ROM to be connected with the GC game in VBA-M as if it were a regular GBA ROM.
 
* There will be that splash screen, but if you do nothing the GBA game starts as usual and the connection doesn't actually happen. What you must do is to hold '''Select+Start''' while the BIOS is loading. This will cause the BIOS animation to stop and wait for connections, and the regular GBA ROM game won't boot immediately. If it goes as intended, VBA-M will stutter a bit and the connection will be initiated.
 
* Dolphin should recognize the Joybus Link by then and the GC game will detect that a GBA unit was connected.
 
* To connect other GBA units, open another VBA-M instance and repeat what you did with VBA-M.
 
 
 
Please note e-Reader functionality with GC games isn't emulated as of yet.
 
 
 
====Dolphin and other emulators====
 
Dolphin devs are working at rewriting the entire GBA connectivity code in a far better way from scratch with more accurate emulators. They did a video using the higan emulator. Nothing of the sort is published at the moment.
 
 
 
===GBA/DS Connectivity===
 
Inserting a GBA card in Slot-2 in a Nintendo DS unit (that's not a DSi) while a DS game is running could unlock various gameplay features in some DS games. DesMume can emulate this: while playing the DS ROM, go to "Config, Slot 2 (GBA Slot)" and select "GBA Cartridge". Now select the GBA ROM file, and make sure its sav file is in the same folder. You may need to reset the game sometimes to see the effect in-game.
 
 
 
===e-Reader===
 
A device that connects to the GBA, which can read content off e-Card paper stripes either as standalone content, or additional content to GBA games (or even GC ones). Also known as the GBA's DLC.
 
 
 
''Main Page: [[GBA e-Reader emulators]]''
 
 
 
==Special Hardware==
 
Most of these have not been emulated as of yet. There used to be patches that could be applied to GBA ROMs with a utility like LunarIPS (mostly from [http://bubbz.pocketheaven.com/?system=gba&section=patch No Frills]), but they're for the most part lost to time nowadays. Your best bet is to use Action Replay to emulate those.
 
 
 
===Solar Sensor===
 
====Emulation====
 
This feature has been emulated in both mGBA and no$gba 2.6 onwards:
 
* mGBA: Under '''Emulation/Solar Sensor'''. You can fine tune brightness levels as you wish, either increasing or decreasing it by in-game increments, or setting it at either maximum levels.
 
* no$GBA: Under '''Options/Emulation Setup''', you can find the Solar Sensor Level option. You are given the choice between only three brightness levels though: Darkness, 100 Watts, and Bright Sunlight.
 
====ROM Patches====
 
Fixes applied directly to the ROM by various scene release groups to make it compatible with any emulator/flashcard, making the in-game brightness level controllable with L+Left/Right. It's argued this makes for a better experience actually, but sadly not all releases are covered.

* Combinations of Boktai 4 JP with earlier solar sensors to get solar sensor bonuses aren't emulated yet in any DS emulator.
 
  
===Motion Control===
+
The good news is the efforts currently underway are starting to see real effects. While it's true that Cxbx-Reloaded will have the upper hand with a primarily HLE-based approach on Windows, XQEMU will have the advantage of going by the book. XQEMU also has the potential to tap into hardware acceleration that Cxbx-Reloaded would have to write a kernel mode driver for, and SoullessSentinel wrote "''I don't think our users would like the idea of disabling security features such as driver signature enforcement and installing an untrusted kernel driver just for an emulator.''"<ref name=accel>[https://www.reddit.com/r/emulation/comments/6a958p/cxbx_reloaded_xbox_emulator_panzer_dragoon_orta/dhetzrd/ Cxbx-Reloaded (Xbox Emulator) - Panzer Dragoon Orta (In-Game)]. Reddit (2017-05-10).</ref>
VBA-M has an option for Motion controls "Input, Set, Motion". It currently works with all versions of the GBC title Yoshi Tilt'n Tumble, which also was a special cartridge with a motion sensor built-in to control movement in-game. But VBA-M does not support motion controls for GBA games yet.
+
<!-- The Nouveau project for Linux may be of help figuring out the GeForce hardware in the Xbox{{Cite}} -->
====Emulation====
 
* VBA '''doesn't''' emulate this feature, and its "Motion Control" option (with keys mapped to each tilt direction) covers the GBC title Kirby Tilt'n Tumble.
 
* mGBA supposedly includes this feature but key remapping for tilt sensors is not present in the latest builds.
 
====ROM Patches====
 
Fixes applied directly to the ROM (with the LunarIPS utility, or at runtime using mGBA or VBA-M and naming them the same as the ROM in the same directory) by various scene release groups to make it compatible with any emulator/flashcard. D-Pad controls substituting motion controls don't work as well here as they tilt it "too much" at times to be very playable.
 
* Yoshi Topsy Turvy/Universal Gravitation: [http://www.advanscene.com/html/Releases/dbreleases.php?id=1799 JP], [http://www.advanscene.com/html/Releases/dbreleases.php?id=1947 EU], [http://www.advanscene.com/html/Releases/dbreleases.php?id=2001 US]

===Rumble Feature===
+
==Chihiro==
There are various rumble features found in GBA/GBC cards:
+
The Chihiro arcade system was produced by Sega in 2003. It consists of an Xbox motherboard (with double the RAM as with devkits) with additional boards for handling arcade I/O (Sega JVS standard). As the inner workings of the Xbox are better understood, Chihiro emulation support and accuracy will improve.
* '''GBC Rumble:''' GBC games which came on special cartridges with additional hardware for the rumble feature. It was actually used by dozens of releases, and some games like Tarzan 2 GBC were programmed to have rumble support but shipped on regular cartridges. Emulated by VBA-M GX (Wii-only), which also cover the dummied-out rumble games. Not emulated anywhere else.
 
* '''GBA Gyro Rumble:''' WarioWare Twisted was shipped on a cart with rumble support. It would rumble when you tilt to one "extreme". Emulated by VBA-M GX (Wii-only, functional), mGBA has this feature but it's not enabled in current builds.
 
* '''GBA Variable Rumble:''' Drill Dozer has rumble support, with variable force and speed depending on the rock type you drill through ingame. Partially emulated by VBA-M GX (Wii-only, functional), mGBA has this feature but it's not enabled in current builds.
 
* '''Game Boy Player Rumble:''' Many regular GBA games, shipped on regular cartridges, enable rumble during gameplay when played on GB Player hardware (which is essentially GBA hardware). These include Super Mario Advance 4, Summon Night Hajimari no Ishi, Mario & Luigi 1, Shikakui Atama wo Marukusuru Advance (both releases), Pokémon Pinball, as well as Drill Dozer which disables its original cartridge rumble scheme and enables this one instead. None of the emulators support this, though it's being under development for the mGBA emulator.

Emulated

The Xbox is a sixth-generation console released by Microsoft on November 15, 2001. Known as the DirectXbox during development, it is notable for the specs having similarities to a PC, namely as a result of using familiar components around the x86 architecture. It had a custom Pentium III CPU at 733 MHz with 64 MB of RAM, and a custom Nvidia GPU codenamed NV2A at 233 MHz. The Xbox was often said to be the most powerful console from the sixth generation, and Sega later designed the Chihiro arcade system with the same components. It retailed at $299.99.

The Xbox was a modest seller, and helped create a brand for Microsoft that would give its successor a stronger market share in the west; despite Microsoft's best efforts the original Xbox and succeeding consoles from the company have never gained a foothold in Japan for various reasons.[1] It had a number of advantages over other sixth-gen consoles at the time; it was the only console to include a hard disk,[N 1] meaning it was the first to be able to rip CDs, and it was the first and only console of the lineup to include a unified online service called Xbox Live,[N 2] prompting Sony to create the PlayStation Network the next generation.

Early in its lifespan, the Xbox had an unusually active modding scene compared to the other consoles (often vindicated by the incredibly short warranty). Upon the first jailbreak by Andrew Huang, the scene ultimately delivered no comprehensive emulation until the mid-2010s,[N 3] where developers have continued to have issues owing to the fact that, alongside the poorly documented hardware, many of the Xbox's games either came from Windows or were then released for Windows afterward (though it does retain a few exclusives). However, the Xbox emulation scene has been resurging with two emulators at the forefront since mid-2017. Its developers continue to say there's no competition between them, as they're both open-source and have different goals and methods.[2][3]

Emulators

Note: xboxdevwiki's own list of emulators contain over 20 different emulator projects, most of which were abandoned not long after they started. Only about 2 or 4 emulators have been making progress.

Comparisons

Since May 2017, serious strides have been happening in the Xbox emulation scene with Cxbx-Reloaded and XQEMU making major progress. Cxbx-Reloaded went in-game for Jet Set Radio Future with a somewhat decent framerate.[4] Many more original Xbox games have been able to get in-game and, in some cases, at decent speeds on XQEMU.[5][6]

PC

xemu
A low-level emulator by Matt Borgerson continuing much of the work done on XQEMU. Focuses on stability, performance, and ease of use. 600+ games are reported playable, See the official game compatibility list.
Cxbx-Reloaded
A fork of Cxbx that's been having a good development momentum since mid-2016. It's built for x86_64 machines and includes a ton of improvements to its HLE kernel, some from code originating in Dxbx and other related forks. While it has HLE support for the GPU and other parts (eg. audio) to make many games run fast, XQEMU's LLE implementation was introduced in April 2018 and is expected to help even further. 150+ games are playable and 450+ games ingame. See this compatibility list for more information.
XQEMU
A low-level emulator based on QEMU. It can emulate the BIOS and many games at very slow speeds but is sometimes faster than Cxbx with acceptable graphics. Audio has not been tested but has been assumed to be emulated, just not forwarded to the audio hardware for some reason. See this compatibility list that was taken from John GodGames' 2015 list, and this Google spreadsheet.
StrikeBox
Beginning low-level emulator that just initializes an x86 system and runs whatever is in the ROM. Not much works for this currently. It was uploaded to GitHub on Dec 5, 2017 by mborgerson, a well-known XQEMU contributor who in early 2018 is still focused on streamlining XQEMU's QEMU codebase. So expect more progress from XQEMU than StrikeBox in the meantime.
Cxbx
One of the first Xbox emulators, started as an ahead-of-time compiler for Xbox executables. Can boot around 56 games, with around a dozen in an already playable state. See this compatibility list.
Dxbx
A port of Cxbx to Delphi, expanded with a redesigned symbol detection engine, and many rendering improvements, a new pixel shader converter, etc.
Xeon
Can emulate Halo CE to the point where the first stage is semi-playable. The walls and ground are pitch black, and the game crashes after you complete the first stage or right after you select the difficulty on modern versions of Windows.
MAME
Existing x86 emulation in MAME has given way to an xbox driver... that they've marked overall as not working and sound as unimplemented (graphics are OK though).

Consoles

Fusion
The internal name for backwards compatibility on the Xbox 360. It supports a specific list of games that, while some work right off the bat, may need additional patches to play properly. It also requires your console to have system storage. Some games still have issues with graphical glitches and slowdowns to errors that can make standard gameplay basically impossible. There is more information and references/video(s) about this BC support here.
Fission
The internal name for backward compatibility on the Xbox One and Xbox Series X/S. With a smaller amount of supported games, likely due to issues surrounding licensing,[N 4] it allows the ones that do work to run at twice the Original Xbox's standard resolution (480p) on both Xbox One (S) and Xbox Series S consoles (up to 960p), and more than quadruple on Xbox One X and Xbox Series X consoles (up to 2160p).

Emulation issues

The pratfalls of Xbox emulation

The Xbox is infamous in the emulation scene for being the worst case of false advertising. For the projects currently available and active there's a high barrier to entry for the effort involved, and it's the same reason why consoles using off-the-shelf hardware (or reused hardware) are easier to emulate. To users, being "basically a PC" and "x86-based" is a selling point despite that not being the case as the Xbox has a number of proprietary elements that are nothing like standard PC hardware (like the eighth-gen "x86-based" consoles). Many aspects of the Xbox's architecture aren't openly documented, making it a major pain to have to figure it all out.[7][8][9][10][11] For example the APU, one of two sound processors on the MCPX southbridge chip of the Xbox chipset, is incredibly powerful and uses complex processing steps that are difficult to figure out using clean-room reverse engineering.

The good news is the efforts currently underway are starting to see real effects. While it's true that Cxbx-Reloaded will have the upper hand with a primarily HLE-based approach on Windows, XQEMU will have the advantage of going by the book. XQEMU also has the potential to tap into hardware acceleration that Cxbx-Reloaded would have to write a kernel mode driver for, and SoullessSentinel wrote "I don't think our users would like the idea of disabling security features such as driver signature enforcement and installing an untrusted kernel driver just for an emulator."[12]

Chihiro

The Chihiro arcade system was produced by Sega in 2003. It consists of an Xbox motherboard (with double the RAM as with devkits) with additional boards for handling arcade I/O (Sega JVS standard). As the inner workings of the Xbox are better understood, Chihiro emulation support and accuracy will improve.

Notes

  1. The PlayStation 2 also had a hard disk accessory, but the Xbox had it built-in on all models. Consoles in the seventh generation and onward began to include internal storage in varying forms.
  2. The Dreamcast had Sega Net in North America and Dreamarena in Europe, but Xbox Live was the same for all regions.
  3. The Xbox would have been too difficult to emulate at the time anyway as its specs often rivaled that of consumer PCs, and it was alleged that many developers received legal threats from Microsoft to dissuade them from trying.
  4. Which can be a number of reasons, including but not limited to developers and publishers going defunct, movie and toy tie-in licenses for branded content expiring, and music royalties.
