I am still a bit irritated by the fact that the AT27C010 without a window is labelled as Polar Star 2 but when I look at the Hex editor is says 2010 and Puerto Prinsesa.
Yet the label and the ROM match with that MK04 string. Really weird. Maybe it was upgraded at some point?

Thanks, if you put the oki in the right io_map this should be ready to go.
Have you verified Petit Lot actually has no sound hardware, since you put that flag?

ROM_START( petitlot )
ROM_REGION( 0x10000, "maincpu", 0 )
ROM_LOAD( "md06_ver4_1.ic6", 0x00000, 0x10000, CRC(ebc81f10) SHA1(28ac52aeadfbf792da95c01b16fb88f7a5eb1d4e) ) // 1xxxxxxxxxxxxxxx = 0xFF

this is romcmp's output in a comment, it isn't subject to MAME's preference for lowercase hex.

No I could not verify it and was going off the description in the header that the Oki is unpopulated on Petit Lot. Didn't think about how the Z80 might be doing sound.
