Today, I'm releasing PSX-GS -- a plugin for epsxe and other PSEmu-compatible emulators on Linux to allow the use of Game Shark / Pro Action Replay codes. Winblows users have had this functionality long enough!

PSX-GS is licensed under the GNU General Public License (version 2)(or later), and has been tested with epsxe 1.6.0. You'll need a fairly recent GTK 2 build in order for the UI portion to work properly. Note that codes with correct formatting and improper addresses may crash the emulator. Be sure to read the README.

You can download it here: Source Code, 32-bit x86 Binary

Here's a brief walk-through of how to use it. You can also watch the YouTube video.

1. Start epsxe
2. Open the Video configuration.
3. Select PSX-GS 1.0
4. Click Configure

1. Select the real GPU plugin you want to use. You can access it's configure and about menus via the buttons under the combo box.
2. Go to the second tab.

1. Click the textbox next to the label, and set each key by pressing the desired key once. The text box will then display the key name that was pressed.
2. Click on 'Ok' to save the settings.

1. Fire up your game of choice.
2. Press the Cheat dialog key

1. Enter the code in the upper text box, and a brief description in the lower; then click on Add to add the code to the list. The code will be automatically verified and enabled when clicking Add. If the code is invalid, it will not be added to the list.
2. Click on Save.

1. Choose New Game or perform some other desired action to verify that the code works.

1. Et voila!

If you don't have epsxe installed at ~/.epsxe, you can make the plugin work by doing the following:

1. Make a symlink from your epsxe folder to ~/.epsxe

   $ ln -sf /path/to/epsxe ~/.epsxe

2. Ensure that gsconfig is at ~/.epsxe/cfg/gsconfig

3. Ensure that libGS.so is at ~/.epsxe/plugins/libGS.so

This worked correctly for a friend of mine running Ubuntu 8.10.
