Your information on xqemu is dated. xqemu was forked to xemu a while back. Development of xemu is very active now: many games are now playable with accurate graphics and sound with performance up to native framerates. Improvements to speed and accuracy are coming in on a regular basis. xqemu is basically dead, with its discord shut down and the main developer off the project. Now is a good time play around with xbox emulation if it is of interest to you.
