Hi guys. I use a mac and haven't figured out how to install any cheat fix firmware on my old old old R4, so I did my best to edit the most recent cheat file so only US codes remain.I hope people can find this useful.Some games are missing, like the different IDed GTAs and Chrono Trigger (U).I'm not sure why but this is still better than what I had before.Enjoy to whoever could use this.
