Right, unlike other devices there is no large database of cheat files. You create a *.scc file for each game that contains cheats specific to that game. Editing the cheat file involves re-creating it from scratch, but it's a very simple process. You just format the text file with certain symbols and then use two tools to convert the text file first to CHT format and then SCC format. As rasputin stated, the tutorials on SCCheats should get you going, assuming the cheats you want aren't already included in the SCC files SCCheats has to offer.
