;[[Cxbx-Reloaded]]:This A fork of Cxbx is that's been having a good development momentum since mid-2016. It's built for 64-bit systemsx86_64 machines, and includes a ton of improvements to its [[High/Low_level_emulation|HLE]] kernel, some [[High/Low_level_emulation|LLE]] and from code ported back from originating in Dxbx and other related forks. It's had a good development momentum since mid-2016. 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 support for XQEMU's LLE-GPU implementation was introduced] on in April 1, 2018.

See [https://github.com/Cxbx-Reloaded/game-compatibility/issues this compatibility list].;[[XQEMU]]:An LLE-focused emulator that's also gradually advancingbased 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 latest compat listthis Google spreadsheet] (1000+ games).;OpenXBOX:Beginning LLE emulator that just initializes an x86 system and runs whatever is in the ROM.

[[File:Xbox_looking-good.png|thumb|250px|The pratfalls of Xbox emulation]]Due to a lack of interest, a lack of console-exclusive games, or The Xbox is infamous in some case very toxic behavior or potential legal threats towards developers, the Xbox emulation scene has remained dormant until recentlyfor being the worst case of false advertising. For the projects currently available, and active there is '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. In spite of its very To users, being "basically a PC" and "x86-like hardware, based" is a selling point despite that not being the case as the Xbox has enough a number of proprietary elements to make emulation nonthat are nothing like standard PC hardware (like the eighth-gen "x86-trivialbased" consoles).

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. XQEMU is meant expected to emulate the Chihiro system, though but no Chihiro game is known to work on itright now. ==Resources==*[http://xboxdevwiki.net/Main_Page XboxDevWiki], for Xbox hardware documentation*[https://discordapp.com/invite/26Xjx23 Xbox Emulation Discord server] (For general and development discussions on OG Xbox emulation, especially for CXBX-R, but also XQEMU, OpenXBOX, circa 2018and any legacy emulators.) ==Notes==<references group=N />
