i suspect the lower limit for the battery is about 1.8v - so your protection-module is dead for sure :D

Thanks so much for all this info! Also, do you guys know whether or now I need to replace the FD1149 with a 68000 like on Sega 16s? Everything I’ve seen says no…

Yeah, I got happy ending :D
I bought new eprom programmer and erase & burnt roms once more.
The game works when I replaced just two roms, IC8(15786c) and IC17(15787c).
(You can use 27C1024 or 27C201A, any of them)
I think you'd be better make sure that the programmer works properly or the roms are attached correctly.

and my board didn't suicided yet, so still works fine with original battery (but DO NOT NEED that anymore)
Just to clarify, 27C201A-12JLs like these should work fine?
