Ok thanks, calibrating I/O was the solution, cause wangan 1 was doing the same after lol, but doing I/0 calibration finally can play 2 games thanks!
But i have another problem... i can start yacard, enter game and purchase a ingame card and write my name, but when exit the game and return i dont know how insert the card, the pedal dont work.. theres a key button for insert card?
