Ya see, every time I use the VBA emulator on this computer, the controls will randomly lock up. So say, I'm playing Legend of Zelda: Minish Cap. Every so often, the controls will just refuse to accept further input. That means if I was not pressing any buttons, I'll stand still and refuse to move. If I'm moving in any direction, then my controls will think that I'd like for it to make me walk into a wall for 10 seconds while enemies rape me up the ass. Any way to fix this problem?
Are you using a joypad or the keyboard? The only thing I can suggest if a keyboard is deleting your VBA config file and re-set it up from scratch.
