Unigame has been going through his collection of PCBs and allowing many of them to be dumped. In addition to a number of prototypes I’ll talk about later this also includes several previously undumped Arcadia games; the Amiga based arcade system.
He also had some alternate bios revisions, those have been added too.
Adding them was fairly simple, each game requires a basic bitswap (which only applies to odd bytes) Getting them running was just a case of figuring out the right bitswap in each case, Pharaohs Match had no swapping at all.
The Amiga version of Delta Command is known as New York Warriors
