Thanks, that helped. But I got 2 more questions. 1. How do I up my FPS? I put the speed on the highest it can go. 2. When I saved my game (Pokemon Pearl) and when I went to go play it again, it says my Data is Corrupt, should I use a different emulator?
you should be using No$GBA and the save type (backup media) needs to be changed to 512Kb flash before saving will work. If you have set the speed to 'Ultimate MHz Disaster' then its running as fast as it can, but NDS emulation is still slow, particularly with 3D scenes. Not really anything you can do about that apart from wait for the emulators to improve.
