Mappy 30th Anniversary Edition

Hack of Mappy


In recognition of the 30th anniversary of Mappy by Namco, Makimura Manufacturing has released a patch which converts the sound engine of the original Mappy by taking the old NROM mapper and replacing it with the NAMCOT 106 mapper used in Mappy Kids. The sound in the game is a closer resemblance to its arcade counterpart.

An astonishingly close arcade port for Famicom, but flashcard user Bethesda

Reviewed By: Eadwine on 24 Sep 2022

This hack sounds shockingly close to an original Mappy machine. I always kind of knew that the Namco 163 was based on a similar synthesizer to the chip Namco used in a lot of their 80s hits, but I didn’t realize how close you could get.

One issue though. The music sounds great on emulator but it’s all out of tune on actual hardware. I don’t know if it’s the Everdrive’s implementation of the N163 chip, or if an authentic N163 would also struggle with the tuning like that, but it makes the hack basically unplayable on real hardware for anyone with ears. I’m sure what’s going on is a difference in how emulators and Everdrives mimic the N163 and it’s not directly your fault and the music sounds great on emulators. I’m just bummed.
