I have a prototype cart I'm trying to dump and one of the eproms looks like it's failed. The chip is a TC574000AD. There are 4 like chips on the cart and I can read the other 3 fine. My programmer won't acknowledge the last one- I get a "chip not placed" message. The chip appears externally fine, no indication of damage.
The board will boot and run in a SNES and get through the menus ok but flakes out when you get to the first stage, so it appears the SNES can't read that chip either.
Anything I can do with this personally? Beyond that what are high end options for recovery?
