Some days ago mafer asked for an issue with the "single PCB versions" of Demon Front and SVG, they need the bios files (pgm_t01s.rom and pgm_m01s.rom) inside the zipped ROM to work properly... but in the "FB Alpha ClrMame" dat file there's an apparent contradiction: if I understood correctly, the pgm bios files should be merged and not directly in the zipped ROM... maybe does the dat file need an adjustment !?
