I don't have a RPi yet, but just checking it will do what I want. I'm not a linux user either.
Plan is to use the RPi instead of eg the 60in1 card or PC, to play classic games Defender, Robotron, Galaga.
Anyway, can some one confirm or not, that it will be relatively easy to make a new build incorporating the updated williams drivers for Robotron (not yet in MAME). I've done it on PC just fine.
