Our Own NES Game Genie Codes
Monday, September 9, 2013
By: Matthew Doucette

Wow, look at what I just stumbled upon. My old NES Game Genie codes, ones I invented when I was child.

I recall how I invented some of them. My Game Genie would not remember the codes last used and there was no way to revisit the code entry screen, so if you discovered a good code it would be lost unless you recorded it or memorized it somehow. Losing codes like this happened over and over with me, so I devised a solution. I coded a program on my Tandy 1000 SX, the computer I owned after my TI-99/4A, that would generated random Game Genie codes. I printed off hundreds to thousands of them on a sheet of paper and used them to experiment with the Game Genie. When a code would do something cool, I would have it recorded.

That said, I am sure that some of the codes below are derivatives base off the official Game Genie codes. I have no idea which unless I were to cross-reference them. If you happen to do this, please let me know.

I also see I have well-known cheat codes listed in the mix. I left these in to maintain the list as an accurate recording of the file I had as a child of all my gaming cheats.

Without further ado, the codes.
