@mitu I've tried both .bin and .zip, the hash file for astrocde says .bin files as well as all the BIOS files zipped in the roms directory as well as being in the main BIOS directory. Still no dice.
Done and done. GitHub isn't nearly as scary as I had imagined. I hope to work my way up to a script module submission when I have some time to learn a bit more. For now, I made some small revisions to my previous Astrocade artwork to make everything read a bit more cleanly.
