I am going to buy an Ultimate Arcade II cabinet kit and I wonder if I can make a little door on the bottom of the front of the cabinet in order to access the insde. One with a lock on it such as the Pac-MAMEA. This would be to access the internal computer or interchange game systems or something else. If anyone could help in telling me whether or not I can do this (and how if I can) or another way to access the inside easily (through keyboard slot, coin thing) that would be great. Thanks.
