misc/astrcorp.cpp: freezing in magibomb sets

[Cristiano-MDQ]

This patent seems to confirm this comment and is perhaps the reason for some sets to freeze after a few plays. #10235 (comment)

Magibombf behaves exactly as described and freezes, requiring a soft reset to work again.

it's not related to any freezing, the TMSS is a hardware thing, if it doesn't get the code it wants it will freeze the CPU, so if you don't emulate it all, it will never freeze.

it is unclear why the games write the TMSS sequence, as it doesn't look possible for there to be even a repurposed TMSS there, absolutely nothing about the rest of the hardware is similar to a Genesis, the only thing they have in common is a 68000

imho sounds plausible they had RE-d the TMSS in a way so to be reused for their needs, which implies rearranging its pinout.
Do we have PCB pics for these?
