Arcade Offset (Patched MRA Files)

This repository will include encrypted patches for titles available on jotego's Capcom Play System cores. In the future, I may continue patching other titles for various cores playable on MiSTerFPGA.

These patches are designed to work with encrypted roms from mame 0229 or higher. The intent is to alleviate the need for additional roms in games/mame.

This section will be expanded at a later date.

Patched MRA Format

While most of this should be self explanitory, this is the provided layout used. Patches are applied to the loaded roms from rom index="0". Additional information may be provided from "soft dip" settings saved to the eeprom/nvram save .nvm file. The hex is taken from "soft dip" settings and appllied to rom index="02".
