The commit to the source has just been made. Turns out the 2 "bad" roms mentioned in the source are actually the same on this PCB, so they didn't change.
However caius did measurements from the PCB so the bootlegs are going to sound radically different in terms of speed then before. But again this is using actual measurements from the PCB plugged into the driver.
As mentioned, Bill's Blood Bros. is the US Fabtek license so it's good to have that finally dumped!
