Read Team Europe's latest blog entry of More MCUs of taking down more of those nuisance i8751 microcontrollers. "Controllers be gone".

Still plenty more of those on other Irem M72 world region pcbs yet to be dealt with.

* comments from file src/mame/drivers/m72.cpp *

// in the case of the i8751 protected games the World and Japan sets should be using different MCU roms.
// the MCU roms provide checksum information needed for the sets, so using the wrong ROM will result in
// the program roms failing their tests. This is why we still have simulation code for many games
// despite having Japanese version MCU roms for several of them.
