Circuit USA Game Genie Codes (Japan)
If you are unfamiliar with Game Genie or Pro Action Replay (PAR) cheats and how to use them - fear not! Both of these things are usually found under the Cheat tab if you're playing on an Emulator which is located on the Toolbar at the top of the Emulator's window. If you're playing with an actual physical console you'll need to purchase a physical Game Genie or Pro Action Replay and use the codes that way.
Those of you out there who are playing on an SNES Emulator that need help figuring out how to use the codes on this page should visit my how to setup Game Genie and PAR codes for SNES guide. That guide will go into a lot of detail about how to setup and use the codes you find on these pages and some trouble shooting tips for those who need them.
