I just tried SEVERAL ROMS and i have to says im impress so far.
What i have tried are the following :
Dk 64 work arround 15-30fps
San fransico rush 2049 boot and all no audio and crash on tire smoke
Space station sillicon valley 18-30fps 60fps in some cutscene wonderfull with 3d on
I will test some more!
Edit: just tested hexen64 and it works im crying 12-30fps
Quest 64 seems run good but no on screen render graphics what a bum but it run so lets cross finger
Now to test aydyn chronicle first mage ,conker bad fur day, and many more!
All are USA roms
