Pandoras Box 4 is one of the easiest ways to convert a single JAMMA arcade cabinet into a multi game MAME; but is it worth it? With 645 games on one PCB how does it handle presentation, emulation and overall value? Spoiler: pretty well ually.\rbr\rbrNote: I re-uploaded this video after identifying (thanks to youtuber dankcushions ) the true function of Quality Optimization on the Pandoras Box unit. Its a critical feature to take note of and justified adding that section to the video.\rbr\rbrI should also note there is a 10Watt mono amp built into this PCB that you can use.
