Thanks for this, dmitry_smagin and hi-ban. Fantastic emulator, one of the best i've ever used (only handheld NES emu that matches it is notaz's for GP2X/Wiz, that's saying a lot!)
I noticed a bug: in order to load a save state you must hit B instead of A, despite what the screen instructs.
Fixing that, and adding controls remapping will make it perfect. Thanks again.
