The cheats I have worked on and provided are not codebreaker, Game Genie, Game Shark etc. But Rather from the RA Cheat Search function.
Here is the folder links
Some of the cheats can be left on so that the number values stays the same for example Health, MP, Items, XP, Stamina, Ammo, Fuel, etc. Most of the cheats I worked on deal with those but sometimes It’s Ideal to turn them on, let the effects take place and then turn off the cheat/s. I would also pay attention to the game version and the region as these may not work on different regions. Most of the cheats I have provided are from the USA region.
