This is one of the best homebrews of any out there...
I would like to suggest the option in the cheats section, of downloading and installing ALL cheats, whether the game is installed or not.
I mention this because it seems that if the game's id that you have installed differs from the cheat id for that game then it will NOT download the cheat and it will seem the game has not cheats.
However, if the cheat is downloaded and the game is the same but the id's don't match, edizon will actually tell you that you have cheats for the game, but the game id and or version id (the bid) are wrong and then you know that the game actually has cheats you just need to change the game's id and or bid in the cheat file and there's a good chance they will work.
But if the cheat is never downloaded then it will seem the game doesn't have any. So by giving the option to download ALL cheats, users can maybe download them once a week or once a month and then just use the "cheats update" option inbetween to update and or add any cheats for games already installed.
