There are prolly hundreds of Pac and Mrs. Pac mods and upgrades out there.. Some are just a chip, some are an aux pcb.. Totally depends what you want man.. Have a buddy who sells a aux pcb that pops on and offers 3 versions of each pac, fast and slow.. I've got one in my game that has hundreds of versions, fast, slow, cheat, pause.. The good ones are screen changeable.. Not by flipping a switch
