In depth usage guide:
This program will allow you to use cheat codes on your Wii games.
What you need:
Ocarina (downloads above)
1 SD card
Homebrew Channel installed (there are 8,429 threads on how to install it, use the search button!)
The game you want to cheat in.
1 PC (laptop or desktop) running Windows or Linux with Wine.
How to cheat.
First, download the files above. Then extract them with your favorite extractor (if you don't have one, get WinRAR). Open program codemgr (skull icon). Now you'll have to open the codes you want. They are all named with the 4 letter game code, so do a search online (google!) for your games code, or just randomly open them up to see. Select the codes you want (by placing a check mark in the box next to it). When your done selecting codes for that game, at the VERY VERY BOTTOM, there is a LONG button named "Export to GCT". With your SD card connected to your PC, press this button, and select the SD cards drive letter from the drop down menu. Press STORE, not Store to File. When you've finished for all your games, take your SD card and put it in your Wii, boot up the HomeBrew Channel, launch Ocarina, pop in your game disc, and cheat away!
Frequently Asked Questions;
Q : When will codes for xxxxxxxx be out?
A : When ever you make them, or someone finds time to make them. When datel makes cheat codes, they have hundreds of people working on it at once, with almost unlimited financial resources. Right now, the only people that are working on Ocarina are regular people like you and me.
Q : Can I play my backed up or copied game with this?
A : NO!!!! NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO!!!!!!!! STOP ASKING!!! look at my avatar!!
Q : The game xxxxxxxx crashes when I try to play it! WTF! FIX IT!!
A : You've either selected too many codes, or have a bad code selected. Try the game with fewer codes enabled, and if it's still crashing, you'll have to try each code separately.
Q : Can I turn on and off codes from my Wii?
A : No, not yet. You can only select the codes on your PC. There is no "On the fly" code selections yet. This is still very new, so it's not like a GameShark yet.
Q : Where's the online codes for Mario Kart and Brawl?
A : You can't cheat online yet, if ever. Cheating online means sending the cheat codes along with all the other data. When that happens, Nintendo's online servers drop your connection. Basically, you'll never get an opponent. Plus, online cheaters suck!
Q : How do I use Gamecube cheats?
A : You need to decrypt the Gamecube cheats with gcncrypt, take that data and use WiiRD to convert it to the TXT file needed for CodeMGR. (A full guide will be posted later) Credit for this goes to dahun
