In other words, like the NES 8 bit carts, can the rom be desoldiered from the board, cleaned up and have a new rom chip (same size of course) programmed with an eprom burner and resoldiered to the board and become the new game without anything special done to the board or chip? Any help would be appreciated before I buy a bunch of doner carts... I want to put some of my own roms onto the real boards without having to create new boards or buy expensive multicarts... Thanks! - Daryl
