I have not used this to burn amiga kickroms because i have never needed it to but I have burned other stuff. you might have to modify the above sequence depending on the motherboard setup. i also have not checked rom pinouts and stuff. this procedure has been used for years to burn game roms for old consoles. i thought i was so clever when i came up with it, then i found out that at least one other person had done it before. use this flipped out knowledge at your own risk.
