right now I am only using a wireless keyboard. I will be using a ipac4 from ultimarc and will only have arcade controls connected. So the way to exit game is to hold select and esc at the same time? is there anyway to change it to only pressing ESC to exit?

the ipac uses standard mame shortcut by pressing P1 Start and P2 start at the same time is like pressing ESC

mame4all works like this as default, only problem is a few roms play much better with mame2003
