Code Types are used by Game Enhancer's to determine how to use/execute codes. They also allow users to add some degree of sophistication for the codes they make.
Types you will commonly see available for most Game Enhancers are 8-bit/16-bit/32-bit Writes, Conditional types (If - Equal To, Greater Than, Less Than, etc.) and Master Codes.
Some devices don't have any Code Types at all, and just perform a preset bit write to the address you define. Such devices are the older models of the Pro Action Replay for Super Nintendo and Sega Genesis.
