Both Raw and Pro Action Replay are essentially the same thing, the only difference is the colon that comes right before the data value in the Raw format. Once you've found the cheat you want, you'll need to display it in a form that you can enter into SNES9x.

First thing to do is search this site for the cheats you want. Now that you understand what the codes do and how they differ, lets get into the nitty-gritty of how to make use of them on SNES9x. ROM codes on the other hand pretty much require you to disassemble the game and go through the program code line-by-line and figure out how it works and what you can change to get the effect you're looking for. Using an emulator or a device like a Pro Action Replay, you can stop & start the game and search RAM for specific values that you expect to find, or search for RAM locations that changed since the last time you ran a scan.

The advantage of RAM codes is that they are *much* easier to find on your own. This means that simpler devices like the Game Genie can't work with them because the Game Genie just sits between the cartridge and the console and whenever the CPU tries to access a certain ROM address the Game Genie checks its internal list of codes you entered, and if the address is listed it returns the data value that was part of the code. Why ROM vs RAM codes? Well RAM codes on the 'real thing' require special hardware which can install interrupt handlers. A RAM patch does something very similar, but instead of being executed as part of the program, a special interrupt handler is installed and periodically rewrites the RAM location with the data value you requested. This can be handy to stop the game from altering a counter such as how many lives you have, how many shots you can fire, how much life force you have, things like that. What a ROM patch does in many cases is insert a NOP or no-op which causes the program to do nothing when it executes that instruction. These are generally known as address/data pairs. How do they do this? The code specifies an address, either RAM or ROM, and a data value. What they do is patch the game program, or in some cases lock RAM addresses to a constant value. Have you been using SNES9x to play lots of the old SNES games and been having a good time? Found a lot of games that are just too hard, or maybe not that much fun so you want to try out the cheats?
