If using a AX5202P (MMc3) verified compatible with TLROM, TGROM, TSROM, TKROM, and TNROM mapper types. Please note that other mappers have not yet been tested.
If using a AX5904 (MMC1) verified compatible with SLROM, SGROM, SKROM, and SNROM mapper types. Please note that other mappers have not yet been tested.
* Please note that is only for some games that have a hard time with newer SRAMs (Faster then 120ns). If you are using older SRAM or your game doesn’t have an issue then it is not needed. By populating C6 this can solve the issue for MMC3 games.
Build instructions/tutorials aren’t available at this time. If you are uncomfortable or new to building your own cartridges please wait for tutorials to become available.
