I'd like to own a cocktail table and play rounds of Batsugun with it's original PCB, so Bomberman and TurboDuo won't beat my ass because I'm using an emulator.
I'd rather have the original PCB boards of the arcade games as well, but changing them to a different game would be frustrating or actually in disguise easy.
Lastly, with the PCB Batsugun, I'll have no buggy graphics, no missing sounds as well, and music available. To bad Grind Stormer is rare because I want to hear the original arcade music.
