Arcade Offset (Patched MRA Files)
This repository will include encrypted patches for titles available on jotego's jtcps1 repository. In the future, I may continue patching other titles for various cores playable on MiSTerFPGA found in the MiSTer-devel repository.
These patches utilize encrypted roms from mame 0.229 or higher. They should work with previous mame sets if no changes were made to the merged rom. The intent of these patched mra files is to alleviate the need for additional roms in games/mame or games/hbmame and patch the merged rom on the fly.
They include unlocked characters, modes, enchancements, trainers, and other features available in the encrypted romsets. The primary usage is to no longer input a code to access hidden characters. Some files may be found in HBMame, although that is not the original source. The readme files for each title show the source of the patch and the author. If none is notated, then the patch has sourced from me.
There are custom .xml files generated to export these enchancements to .mra files when generated. They are located in the rom/xml directory.

Compatibility Notes
Compatibility with jtcps15 as of 20210624:
Currently, the fourth button has been eliminated in jotego's jtcps15 core to fix an issue with Muscle Bomber Duo as no officially released titles utilize more than three buttons on the hardware.
Please use the core linked below separately in Current Titles if you wish to have full 6 button support for Street Fighter Zero (CPS Changer, Japan 201218). If not, you will lose the input for lk/B4.
This will be addressed in the future.

Patched MRA Format
This is the provided layout used for jtcps2. Patches are applied to the loaded roms from rom index="0". Additional information may be provided from soft dip settings in the eeprom/nvram file. The hex is taken from soft dip settings and applied to rom index="02". The rom index usage will vary from core to core dependent upon the author.
As these are generated from a tool chain, they do not mirror the example shown at MiSTer-devel/Main_MiSTer #MRA Format.
