Ocarina Guide

NOTE to Linux Users: Ocarina works 100% in Wine emulation.

Ocarina is the most used program for making GCT files. To use codes for your Wii game, you will need a GCT file containing your desired codes (except for advanced cases such as hex editing an ISO). You can download it HERE, extract/unzip the download. You will see a file called codemanager.exe. Run that file to launch Ocarina. Alternatively, there's also a codemanager1.2.exe file which has an extra option keeping track of amount of lines of code.

Also, here's a sha256 checksum to the Ocarina.zip download for Linux users if desired - HERE

To make a GCT file with one code
1. Launch Ocarina.
2. There is a box at the top left underneath Game ID. Enter in the Game ID. For example, we will put in RMCE01 (for american MKW)
3. On the lefthand bottom side, click the "Add a code/comment/category" button. A prompt will appear. Now enter in a name for your code and click OK. This can be any name you want, just make a name to let you know what the code is for. For example, we will enter in "Code1".
4. Code1 will now be listed on the large left hand box. click on Code1 to highlight it
5. Once highlighted, click in the large box labeled as "Code contents". Type in the actual code in that box, or paste it in. You can find many codes in the Codes Forum HERE
6. Now click the "Store Modifications" button on the bottom right. A prompt will appear saying Data Stored, click OK
7. A blank checkbox is now next to Code1 in the large lefthand box. Click inside the blank checkbox to checkmark it
8. The box is now checkmarked and the word Code1 is highlighted again
9. Click "Export to GCT" button at the very bottom
10. A prompt will appear saying " Codes have been modified.... ... before export?" Click Yes
11. To keep things simple we will click the very top option Store to File. And then browse to the destination you want to store the GCT. Name it the Game ID then ".gct" for the file extrension: Since the game ID we entered earlier was RMCE01, we will name our gct RMCE01.gct. Click Save, GCT file now completed. If you want, you can change the drive letter on the drop down menu (if using Windows) and choose the drive letter where your SD/USB is located. Ocaaina is already configured to find the codes folder and save the GCT there). If you want to save to SD/USB in Linux, choose store to file and find your codes folder within your SD/USB within your /media/yourusername directory.

To add more than 1 code for a GCT file
1. Follow steps 1 - 6 from guide above to add your first code
2. Click the add a code/comment/category button to add a 2nd code name
3. The new code name will be in bold font, but you will notice the code contents are being displayed for the first code you made earlier. To fix this, click on the new code name to highlight it. The prompt for "the codes have changed, do you want to store them... ...." will appear. Click Yes. Code contents box is now empty and ready for codes.
4. Type/Paste in your 2nd code in the contents box. Click Store Modifications and OK.
5. Do this process over and over til you have all the codes you want.
6. Now checkmark all the code name boxes. The 'codes have changed' prompt will appear again. Click Yes.
7. Click Export to GCT. Choose your desired option and save GCT. Congratz
8. Please note if you saved the file directly to SD/USB (regardless of what storing option is used), you may be notified to exit Ocarina when you attempt to unmount/eject the SD/USB. Exit ocarina.

NOTES for newbies:
When you name the GCT file before saving it after export, it must match your Game ID. There our four different Game ID's for MKWii because there are four different regions/versions of MKWii. Here is a list of those Game IDs, choose the one that matches the region/version of MKWii that you are using...

RMCE01.gct = For American MKWii
RMCP01.gct = For European/Australian (PAL) MKWii
RMCJ01.gct = For Japanese/Taiwanese MKWii
RMCK01.gct = For Korean MKWii

NOTES for newbies (for ISO/WBFS users only):
In your usb loader settings, find the ocarina option: Change it to "ON". If you are using a modern version of USB loader GX, you don't need to do anything else, just be sure your settings are saved. If you are using some other usb loader, change the Hooktype setting to "VBI".
