NES-WH




Cartridge Board


Tech Specs:

A chip on board cart 128K of PRG ROM
64K of CHR ROM
MMC1.



The Tech:

This board uses an MMC1 (hidden under the middle blob along with the lockout chip). It uses two ROM chips, and that's about it. It is only found on the Super Mario Bros / Duck Hunt / World Track Meet cart.

See the MMC1 documentation page for information on how the mapper works.
