On IPDB the joust ROMs contain a SOUND12 image in a 32Kbit size. Barracora's ROMs contain a SOUND12 image in a 16Kbit size.
The SOUND12.532 image from joust is not a doubled up version of the SOUND12.716 image from Barracora.
I figure one is mislabaled. Anyone know which? I need to strap a sound board for Barracora. It came in with a Joust ROM is why i noticed this discrepancy.
