Playchoice PCB Variations

Nintendo produced variations of several game PCBs. Although the games may appear to work consistently across variations, these modified PCBs may have compatibility issues when swapping games or adding custom NES conversions. The following is a list of the PCB variations that I have come across.

A note about Mask ROMs and EPROMs: Generally PCBs with EPROMs are more desirable because the game chips can be swapped with other NES compatible EPROMs. Mask ROMs can not be reproduced but, in certain instances, can be swapped with other mask ROMs of the same PCB type. (For example SMB2 and SMB3 Mask ROMs can be interchanged.)

Almost all PCBs with Mask ROMs can be converted to EPROMs without damaging the original game. Please contact me if you would like to know how.

If you know of other PCB variations or oddities, send me an email with photos and I'll post them here.
