today i was cleaning some old NES multi-carts in preparation for selling them, and when i opened one (not a multi-cart actually, but a concorde/supervision ver. of the konami arcade title "pooyan") and flipped the board over to my surprise there were uncovered EPROMs inside!!
i've heard about EPROM's being used in pirate carts because they were cheaper or something, so i'm not trying to assert this is a prototype by any means.
i only brought it to the prototype forum for the EPROM expertise you guys have. my question is: have i just ruined the game? or do EPROMs have to be exposed to high intesity UV spectrum light to be erased/reprogrammed?
also, since i was planning to sell it in the first place, are EPROM-based pirates neccesarily more or less valuable than normal pirates?
