Hi all, where can I find a easy to read description of the BIOS, in order to be able to disassemble and understand the code of old games ? Specifically, how does 0x1fbe (PUT_VRAM) work?
I'm trying to support TIX in hacking Venture, but new I need to alter some details of the initialization code
I've followed for a while the code in the BIOS. It seems written by someone who has never seen a z80 (!!)...
