If you instead wanted for a “repack” as in a pre-configured DEMUL emulator + ROMs (which is illegal to distribute), I can’t provide that. But for technical repair/emulation tweaking , the above is a clean, informative outline.
The need to "repack" the MPR-21931 IC501 data arises from several technical realities. Firstly, "bit rot"—the gradual degradation of data stored on EPROMs and mask ROMs over decades—can corrupt the original dumps. A repack often involves verifying the MD5/SHA1 checksums against known good databases (such as Redump or MAME) to ensure the emulator is fed valid instructions.
