You can use cheats with gamecube games just fine with the latest version of cfg. Just use cfg to download the cheat file,select the codes you want and then save the gct file.CFG will do everything for you and save it in the proper place.
I'm not to sure about the multi disc ripping issue your having.I know it was addressed in cfg already but i'll have to find the information on it first to see what the process is for multi disc games.
I'll have to give it a try. I just know that at least what few I've tried, trying to download the cheat files for the GC games (even on 70mod47), it would insist there is no such file.
If you could find out about the multi-disc games, I would seriously appreciate it. I don't recall if I had the chance to do so before, but thank you for all your help.
Not all games have cheat files available so maybe that's why you got that message.
Unless you meant after you downloaded the cheat file and saved the gct file that the loader said no cheats were available.
Did you make sure that ocarina was turned on in the individual game settings menu?
Here is what the info i found out about multi disc GC games and CFG loader
Taken straight from the cfg loader thread

1. Make sure to put "loader.bin" of devolution to \usb-loader\ folder.
2. Rename ISO file of disc2 to gam2.iso and put in the same folder as disc1.
(EX: usb:\games\whatever folder name\ )
It means you only can see disc1 (game.iso) shows in the game list.
(so there are game.iso and gam2.iso in the game folder)
3. Load/Start disc1 and when disc2 is required (like this picture below),
just simply click on "Eject button". Then the disc2 iso file should be loaded
automatically.
I've never used devolution at all so if that doesn't work then im not sure what to tell you.
