1) Not sure why the games are running quickly? Try pressing F8, I think that turns turbo on and off. You can also press F11 to show the fps and frameskip settings. Play around with those function keys.
2) Some games might not have emulated sound (Undercover Cops, In the Hunt etc) as it’s an older version of mame. Some very old games might need sound samples in the mame folder titled ‘samples’. Check the mame4all pi Google code site and there should be a link on there with instructions.
3) Yes. Press the ‘TAB’ key to open up the menu and then go to input for all and there should be an option called ‘UI Cancel’. Press ‘Enter’ on it and then press start and select. This should map other those buttons to quit to ES.
