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 due to using familiar components around the [[wikipedia:x86|x86]] architecture. It had a custom Pentium III CPU at 733 MHz with 64 MBs 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.

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 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=N2>The [[PlayStation 2 emulators|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.</ref> 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,<ref group=N2>The [[Sega Dreamcast emulators|Dreamcast]] had Sega Net in North America and Dreamarena in Europe, but Xbox Live was the same for all regions.</ref> prompting Sony to create the [[Wikipedia:PlayStation Network|PlayStation Network]] the next generation.

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=N2>The Xbox would have been too difficult to emulate at the time anyway, as its specs often rivaled that of consumer PCs. It was alleged that many developers received legal threats from Microsoft to dissuade them from trying.</ref>, as Xbox homebrew typically relied on stolen XDKs rather than true reverse engineering work. Although developers have continued to have issues because, alongside the poorly documented hardware and repeated uses of the simpler but largely failed HLE approach, there has been little motivation to develop an emulator because 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. Their 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===
;[[XQEMU]]: A [[High/Low_level_emulation|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 is assumed to be emulated, just not forwarded to the audio hardware for some reason.
:;[[xemu]]: A [[High/Low_level_emulation|low-level emulator]] by Matt Borgerson continuing much of the work done on [[XQEMU]]. Focuses on stability, performance, and ease of use. [[xemu]] also supports various [[#Enhancements|enhancements]] and some of the [[#Hardware_features_and_peripherals|system features and peripherals]]. While some titles require powerful hardware for full-speed emulation (see the [[Computer specifications#xemu]] page), CPU performance, particularly [https://www.cpubenchmark.net/singleThread.html single-threaded performance], is often the bottleneck. Additionally, using demanding graphical [[#Enhancements|enhancements]] may also require a strong GPU.
;[[Cxbx]]: One of the first Xbox emulators. It started as an ahead-of-time compiler for Xbox executables.
:;Dxbx: A port of Cxbx to Delphi, expanded with a redesigned symbol detection engine, many rendering improvements, a new pixel shader converter, etc. It ended its development at a similar stage as Cxbx.
:;[[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 (e.g., 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. Beyond this, Cxbx-Reloaded supports various [[#Enhancements|enhancements]] and some of the [[#Hardware_features_and_peripherals|system features and peripherals]]. [https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/issues/1318 Roadmap] for more information about CXBX-Reloaded emulator.
;[[StrikeBox]]: Beginning [[High/Low_level_emulation|low-level emulator]] that just initializes an x86 system and runs whatever is in the ROM. Not much works for this. It was uploaded to GitHub on [https://github.com/StrikerX3/OpenXBOX/commit/16013a6529eec37e997cd0ad1d5495cb83456014 Dec 5, 2017], by mborgerson, a well-known XQEMU contributor.
;Xeon: Can emulate ''Halo: Combat Evolved'' 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. It was noteworthy for being the first emulator to run Halo as well as for predating the PC port of Halo.
;[[MAME]]: Existing x86 emulation in MAME has given way to an Xbox driver. However, [https://github.com/mamedev/mame/blob/master/src/mame/microsoft/xbox.cpp#L221 it's been marked as not working and sound as unimplemented] (graphics are OK, though).

====Consoles====
;[[FU|Fusion]]:The internal name for backward compatibility on the [[Xbox 360 emulators|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. If you  remove the game whitelist; it allows for more Xbox Classic games to be played on the Xbox 360 than are officially supported. Some of the games not officially supported play almost perfectly, however some have various issues. <ref>FrameRater's [https://www.youtube.com/watch?v=YSgzpTG_0c4 360's Xbox Emulator EXPANDED!], [https://www.youtube.com/watch?v=dM3I_QUCMzc Unlocking MORE Xbox Originals on 360] videos about this hack.</ref>
;[[Fission]]:The internal name for backward compatibility on the [[Xbox One emulators|Xbox One]] and [[Xbox Series X and Series S|Xbox Series X/S]]. Supporting much less games likely due to licensing: developers and publishers going defunct, movie and toy tie-in, brands, vehicles, music licenses expiring. However it has better loading times and allows the ones that do work to run at twice the 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).
:Unfortunately, with November 2021 update Microsoft ends the program and said: "This latest and final addition of titles to the backwards compatibility program was only possible through the passion and feedback from the community," Microsoft said. "Your constant requests for specific titles and enhancements encouraged the Backwards Compatibility team to partner with the original creators to preserve thousands of games from over four generations of Xbox. While we continue to stay focused on preserving and enhancing the art form of games, we have reached the limit of our ability to bring new games to the catalog from the past due to licensing, legal and technical constraints. Thank you for being part of this journey with us."<ref>https://www.gamespot.com/articles/xbox-backwards-compatibility-adds-70-more-games-today-as-microsoft-ends-the-program/1100-6498021/</ref>

If you do not [[Modding_consoles/flashcarts#Xbox|mod your console]] you need this dongle which contains a ROM with an XBE which provides some functions for the DVD-Video playback.

*xemu has no Xbox DVD Movie Playback Kit support at the moment, so there is no DVD-Video support. See [https://github.com/xemu-project/xemu/issues/173 this feature request page] for more information about adding this kit emulation to xemu emulator.
*Xbox 360/Fusion has no Xbox DVD Movie Playback Kit support; however no emulation process needed to handle DVD-Video for Xbox 360 anyway. DVD-Video is already supported out-of-the-box.
*Xbox One and Xbox Series consoles (Fission) can play DVD-Video. To watch DVD-Video on those consoles, you first need to install the Blu-ray Player software app which is not only play DVD-Video but also play Blu-ray Video discs.

==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).

[[Cxbx-Reloaded]]<ref>[https://www.youtube.com/watch?v=j36zf7LYjHk MrThunderwing's video: Outrun 2 - Chihiro Beta]</ref> and especially [[xemu]] (the original Xbox emulators) can also run a handful of Chihiro arcade games.<ref>[https://www.youtube.com/@emugamer2610/search?query=chihiro Emu Gamer: Chihiro emulation YouTube videos]</ref>

As the inner workings of the Xbox are better understood, Chihiro emulation support and [[Emulation_accuracy|accuracy]] will improve. [https://github.com/xemu-project/xemu/issues/1442 Feature Request: improving Chihiro emulation for xemu].

==Emulation issues==
[[File:Xbox_looking-good.png|thumb|250px|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 "[[:Category:X86-based|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 "[[:Category:X86-based|x86-based]]" consoles). Many aspects of the Xbox's architecture aren't openly documented, making it a major pain to figure 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.

Despite developments has unfortunately lost momentum in recent years, the good news is the efforts currently underway are starting to see real effects thanks to [https://github.com/Cxbx-Reloaded/Cxbx-Reloaded/graphs/contributors Cxbx-Reloaded] and [https://github.com/xemu-project/xemu/graphs/contributors xemu] teams.
