The xbox one/series consoles run a good number of 360 games dispite the fact that the 360 uses powerPC and the newer consoles are x86.

Sony is out here getting shown up by rpcs3 having about 70℅ of their listed games working perfectly fine by hobbyists reverse engineering the ps3.

Yeah, that’s a problem with a lot of FOSS passion projects. We devs kinda like writting code, but not really documenting it. Hopefully with the influx of devs helping that will improve
