<blockquote>[Xenos] was a playground for experiments — it was developed near the end of the Direct3D 9 era, but still before Direct3D 10, and contained many features not standardized or even available at all on the PC, but when they ended up on the PC, the actual implementation could be significantly different; it also included completely unique features. [...] Contrary to a common misconception, the Xbox 360 [isn't] just a “DirectX 9 box”. It essentially contains a [tile-inspired] mobile-like GPU with much more raw power than a comparable mobile GPU. If you compare the registers of the Xenos and the Qualcomm Adreno 200, you can see that most of them are the same, as they are almost the same GPUs — the Adreno 200 was called the AMD Z430 before having been acquired by Qualcomm and was even referred to as the "mini-Xenos"!"<br>-Triang3l<ref>Triang3l (April 27, 2021).

Due to requiring a large number of resources (see [[Dolphin]] and [[PCSX2]] for specifications for their respective consoles), as well as the hardware not being properly documented yet<ref>[http://www.noxa.org/blog/category/projects/xenia/ Building an Xbox 360 Emulator]</ref>, '''Xbox 360 emulation currently isn't at a point where people can reliably emulate most of the game library.''' However, Xenia is making slowly but surely progress on that front. That, plus the fact that Microsoft has implemented their own official emulation of the system through the Xbox Oneand Series S/X, '''however with November 2021 update Microsoft ends the program'''.
