I have an Irem board that has one of these. According to the datasheet it's an EPROM that doubles as RAM?
The board placement of this chip says PR, I'm guessing it's the program rom but in mame there is no dump of this chip.
Game is Legend of Hero Tonma.
The game on boot sometimes says RAM is bad and it isn't, everything in between has been tested and verified good and this is the last thing left to check.
