My friend JackC asked me to take a look at the Ironclad Wii Virtual Console wad.
After some work --
decrypting the wad (3rd party tool...)
extracting the archives with my donkey kong country wad extractor
and writing a small/simple tool to extract the files from the archive
I managed to get some really nice shots:
I would like to submit this to MAME, since this is almost certainly a proper dump from actual MVS/AES hardware.
The only issue I have is that it came with a single 16mb Cx rom. I split up the Cx into 4x4mb files (as Saurus's other titles of the time are the same).
If anyone has any insight on whether I should leave it as a 16mb, de-interleave it to 8mb, or deinterleave & split it to 4mb (or 2mb) please let me know.
It's a 1996 game.
At this time mostly CHA256 or CHA256B boards were used.
So the layout closest to the original will be 4x32mbit for C-Roms.
Edit:
This should it be then:
