Well. Even if you could run the games it would be slow...
Try to get the newest drivers for your gfx card. That's all I know that can help. If someone else know anything they will probably post it here.
then imagine playing ssb wiith 20-30 fps, now that was annoying. luckely i had a cpu upgrade and it's fine now
and no mercy on nemu... waiting, waiting and more waiting. it's so annoying (again).
