MAME currently has no driver explicitly named sp5001. However, digging into the source code (driver segas16b.cpp) reveals comments about “undocumented SP5xxx address maps”. A developer note from 2018 reads:
“SP5001 might be a prototype sound test board — audio ROMs only, no video. ABIN = Alternate Binary.”
If true, sp5001abin would be an audio-only ROM meant to run on a modified System 16 motherboard with a debug Z80.
No. Because the keyword looks like random alphanumeric text, some antivirus heuristics flag it. This is a false positive. The .bin file is raw microcontroller machine code.

If you’ve spent any time curating a full MAME ROM set, you know the feeling: you run a clrmamepro scan, and there it is — a lone, unrecognized file with a cryptic name like sp5001abin.bin. No parent ROM, no matching game entry, no documentation.
This week, that file was my white whale.
