+OPL accepts `.cht` files in PS2RD format. Each cheat file corresponds to a specific game and must be stored in the `CHT` directory on your device.
+Cheats are structured as hexadecimal codes, with proper headers as descriptions to identify their function.
+You can activate cheats via OPL's graphical interface. Navigate to a games settings, enable cheats and select the desired mode.
+
+### cheat modes
+
+  * Auto Select Cheats:  
+This mode will enable and apply all cheat codes in your `.cht` file to your game automatically.
+
+  * Select Game Cheats:  
+When enabled a cheat selection menu will appear when you launch a game. You can navigate the menu and disable undesired cheats for this launch session. `Mastercode`s cannot be disabled as they are required for any other cheats to be applied.
