Building a reproduction just got easier

With this board you no longer have to search for the correct donor board then worry about chip sizes and pinouts.

By populating different chips on the ReproPak you can select between 4 common mappers. Also choose between CHRRAM or CHRROM, and pick mirroring with a solder jumper. No wiring needed, just solder the chips in the open spots. There is a spot for the Ciclone so your board will run on a NTSC, PAL A, PAL B, and Asian NES system. Cart Plastics and Ciclones are available on this site.

The ReproPak board supports 4 different common mappers:

7 A*ROM 8KB 256KB One 74HC161


The PRG uses 27C010 or 27C020 DIP eproms, or can use 29F010 or 29F020 DIP flash chips. The CHR ROM uses 27C256 or 27C512 DIP eproms. The CHR RAM uses 6264 or 62256 DIP srams. The mapper chips (74HC32 and 74HC161) are also standard DIP parts. The Ciclone is only needed if you have not disabled the lockout chip inside your NES.
