SNES Chip List
This is a list of chip types that appear on SNES PCBs. Note that this is very likely to be incomplete and there are going to be errors due to the lack of information online about them. This listing is very much influenced by bootgod's NES Cart database, and a lot of the information is derived from there. Many thanks to JAPAN SNES MANIA, who identified some of the manufacturers of these chips.
