I've got a early Naomi motherboard that is working apart from error 03 caused by a bad X76F100, usually I'd take one from a scrap board but the only scrap boards I have use the newer 93C46 eeprom. I ordered some X76F100 chips from China thinking I could just program the data from mame on one and solder it in place and be done. Once they arrived I quickly noticed my expensive programmer (Elnec Beeprog 2) doesn't support them though, and neither do any of the other programmers I own.
Plan B was to use the 'dev' bios from mame, this bios looks like it was originally used to repair boards but as nothing is ever simple I am not sure how to use it properly, anyone tried this before? or got documentation for this bios?
Some emulated screen shots of the bios I am talking about.
