- Patched MRA files for encrypted and decrypted titles on jotego's verilog implementation of Capcom Play System hardware.
-
These patches utilize encrypted roms from mame 0.229 or higher. The patched MRA files do not require additional roms in
games/mameorgames/hbmameand patch the rom on the fly. -
Patches include unlocked characters, modes, enchancements, trainers, or other features available in encrypted and decrypted roms. These features may have been previously available by inputting codes or not present prior to the patched data.
-
Readme files for each MRA available cite the author. If none is notated, then the patch has sourced from me or hbmame.
- These patched mra files are available with the popular update_all.sh updater script. Enable Arcade_Offset in the downloader to retrieve them.
This is the provided layout used for jtcps2. Patches are applied to the loaded rom from rom index="0". For roms that use soft dips and store settings in the eeprom (nvram file). Hex is taken from soft dip settings and applied to rom index="02".
Usage of rom index's vary from core and are dependent on the author. These are generated from a tool chain utilized in jtframe, they do not mirror the example shown on MiSTer-devel/Main_MiSTer #MRA Format.
