Converting and restoring Konami M2 hardware - WIP

[Arcade-Projects]

Figured I'd leave this here, as it will be useful to someone in the future.

It's the MOSTLY complete process of forcing non-target games to run on the Konami M2. Since each board is locked down either A) an EEPROM check of the game code or B) and EEPROM check of the game code AND an RTC chip, knowing how it gets done is important.

It's a two part video. One shows my process, second shows me down converting the bios on the board (which was booting nothing when I received if as a repair project) and hex editing the ISO to get Tobe! Polystars booting on a Heat of Eleven 98 board.

I still need to finish hacking out the RTC check but not 100% done on that yet

Questions? Just lmk! Thoughts on how to remove the RTC? Also lmk
