Managed to get the board booting games, so that’s an improvement over its original status as a rare doorstop.
The fact I got it running Tobe! Polystars is even better, since it’s one of my favorite shmups and now the friend of mine who owns the board gets to check it out.
Still need to crack a secondary security check in the rev 2 bios file. Part 3 will be me writing custom bios’ and testing them on blank 27C160 chips. Should be fun (unless I fail totally lol)
