For anyone too lazy to make a GCt with the Gamcueb Support (V2) code, here's one.
Let's see if somebody can help me. I am trying to use the classic controller and the GameCube controller to work with this game and I can't get any of them to work. I downloaded the files mentioned on this thread but I don't know exactly which ones to download, where to paste them and what the contents should be, because everyone mentions different ones and the person who explained a bit more one of the files is not available. So I found out that if you click Settings when launching a game on USB Loader GX there is an Ocarina Menu where to download and activate directly the cheats and I tried that. I launched the game but the classic controller still doesn't work. However, I've never activated any cheats before and I don't know if I'm skipping any steps. Also, the cheat says "requires MF patch"?
EDIT (solved):
OK, I think it's working now, I'll double check just in case and I'll try the same for Donkey Kong Country Returns. For those with problems, this is how it is working for me now. I hope that I can help somebody as I've been helped before by other users in here.
First of all, you need to have the Ocarina app, which I didn't have, on the apps folder on your SD card (
http://www.mediafire.com/file/c47btk71s7y7kcs/Ocarina.rar).
Secondly, there are two types of files you need for each game, one is a TXT file that has the cheats written (
http://geckocodes.org/index.php?c=SUKE01) and the second one is a CGT file that is produced. USB Loader GX or Codemgr (included with Ocarina download) both have the option to create the CGT file. The text file goes in a folder named
txtcodes and the GCT files in a folder called
codes, as explained in this guide (
https://gbatemp.net/threads/ocarina-cheats-guide.468862/). USB Loader GX puts them there by default.
Thirdly, for avoiding the black screen, you need to create another text file with the content posted by
boraborawayway on this very thread (
http://crediar.no-ip.com/krtdcd.txt).
Additionally, if you are using USB Loader GX, select the game, click on Settings, Game Load, Ocarina > ON.
With the cheat I am using for supporting the Classic Controller you can also use the SNES controller of the Nintendo Club and the SNES controller of SNES Classic Mini, like in any other Wii game that supports the Classic Controller.
I am still trying to figure out how to use super inhale and the GameCube controller.
