Put a copy of the PROGRAM ROM for each game in this directory.
You need to interleave it / combine it first.

e.g. for VF2, interleave PROGRAM 0 and PROGRAM 1, then interleave PROGRAM 2
and PROGRAM 3, and finally merge those two files together.
Then put in here as vf21.rom, and it will be disassembled into vf21.dis
