Group new to this stuff, but a Diehard gamer from the 80's . Anway just built a mame machine and running gameex and a jpac and mame. Just wanted to know if theres an easier way to map the keys for selecting games, exiting games etc. I can play the games no problem, but trying to explain to my future gamers ( 5yrs old and 10) the multiple button pushed to select and move around gameex/mame is exhausting is there an easier way? Also how does one save there high scores ? I didnt see anything in the setup for it?
