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.
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)].

==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. <!-- XQEMU is expected to emulate the Chihiro system but no Chihiro game is known to work on it right now. -->
