psx4iPhone control problem

I'm trying to play Digimon World and Digimon World 3, well the game starts up perfectly(slow obviously not full speed) but in the start menu I keep pressing start and it wont pick up the action, or any other button i play doesnt do anything, and this happens for both games, if anybody helps thanx in advance ;D

The only PSX game that I have for my psx4iphone is Spryo the Dragon, and the only problem that I have with that game is lag. I wish I knew what to tell you, maybe you have to wait for a minute after you come to the start menu before you try clicking any buttons. Best of luck,
