MASKROM A Mask ROM is a type of read-only memory chip that is used in almost all SNES games. The Mask ROM contains the game binary. When dumped, a ROM image file is created. Since the game binaries are usually on Mask ROMs, the term "ROM" is synonymous with the dumped game binary, although this is not the technical term. Information on Mask ROM chips on the internet is very limited, so I will not claim that I have all the information correct. One of my main sources is bootgod's NES Cart DB. LH538
