Hi, While only new to MAME, I have a working machine, I am using Mala and everything works fine, however after a something a little better whats why I found my way here. I have installed however only the joystick and two of the buttons work. One for back and the other for exit. Its the same on LaunchBox and BigBox. Unable to find mapping key anywhere. Can someone help, it would be great I could select and play a game without using the keyboard to push ENTER. THanks in advance. mark
