The SCDS1 cheat engine is by far, the worst cheat engine of any Flashcard. Currently it doesn't support the GBATemp Cheat Database unless you use a custom firmware/loader at the cost of some of the stock SCDS1 features not working/being supported on the custom firmware.
Without a custom loader, every game on the Supercard has to have its own scc cheat file, meaning that to have all the Cheat Database cheats, you have to have over 800 cheat files. Also the names, descriptions and notes of the cheats are limit to 13 characters total, thats it. If the information is longer than 13 characters, it gets cut off. So you need to have an in game guide file or a text file for every game as well that list all the cheats and how to use them.
