The SharpNES actualy runs faster without fps hack i did (2 CPU update, 1 CPU Draw) and gain enormous speed.
- No sound (like the other one that i know of)
- Only one game (Super Mario Bros 3)...
- No save
XNA is hard to make a GUI as advanced as Silverlight so no game-change or save
Well i hope you like it
