TGB-Dual Help

The controls for the TGB-Dual emulator don't work at all. And I can't change them as well. Is there any way I can correct this?

edit: I just saw the Gameboy Advance Multiplayer sticky and I'm sure this doesn't go under that sticky. TGB-Dual is a GBC emulator.

Which version you're using? If you're using a non translated version like the latest one, enter the first item (keys) on the second menu (Options), now click each box and press the key you want to use. to remap your keys. You might like BGB or KIGB too.
