R - It ENABLES (Green) and DISABLES (Red) cheats
To switch cheats ON and OFF during play, you can press L+R+START to ENABLE cheats; L+R+SELECT to DISABLE cheats.
You can select the cheats for a rom from the gold data selection tab (where rom info,SMS and NES/PCE... support are).
Be warned: previous register values will not be saved when you switch on cheats, so if the game does not update them when you switch cheats off they will remain active since the game does not update the values. If the game checks those values and corrects them you will be best working from the key combos.

An options menu pops up prior to writing the ROM under "cheat information", hit the "..." button, navigate to the "data" folder (located within the EZ-MANAGER folder), then choose the cht file for your ROM. You cannot use cheats for games in the 256mbit region.
