The PSP, or PlayStation Portable, is a hand-held video game console produced by Sony. Though it does not natively support games from other consoles, you can install an emulator on the PSP to play ROM files, or cartridge image files, from the Nintendo Game Boy Advance hand-held console. One of those emulators, gpSP, also possesses a cheat functionality that accepts GameShark and Action Replay cheat codes. In order to import these codes, you must create and import a ".cht" file with your game.

Skill level:
Moderately Challenging


  1. 1

    Open Notepad and click "File" and "Save As."

  2. 2

    Enter the exact file name of your ROM file, but change the extension to ".cht." For example, if your game file is "Final Fantasy IV Advance.gba," your cheat file will be "Final Fantasy IV Advance.cht." You will create one cheat file for each game.

  3. 3

    Copy and paste the cheat codes you wish to use into Notepad. Make sure each code takes up only one line. In addition, make sure there is a 1-line gap between each cheat code.

  4. 4

    Add a header before each cheat code. The header should start with the version of the hardware you are using and end with a custom name of your choosing. For example, if you are using a code from the GameShark Version 3 and your cheat code is called "WalkThroughWalls," enter "gameshark_v3 WalkThroughWalls" for your header. For the Pro Action Replay, use "PAR" followed by the version number, similar to the GameShark formatting.

  5. 5

    Copy your finished cheat file to the same directory as the ROM file.

  6. 6

    Open gpSP and load your ROM. Go to the "Cheats/Misc" menu to enable or disable each cheat individually.

Tips and warnings

  • Downloading ROM images of games you do not own is considered software piracy and is illegal in most countries. Only use the gpSP emulator in conjunction with legal ROM files.
