Unfortunately, I couldn't figure out the keys to play the game, so I could move the mouse pointer, to config.sys, but it wouldn't do anything..
I think by default the emulator keys are these: Enter = Start, F = A button and D = B button
I'll add this to the post; I just noticed it's hard to see the emulator interface because the buttons are white, and the game is also white...
Thanks! I managed to set up my party and play a battle now :)
