This involves installing Wii homebrew if you haven’t already. Then, you must install the homebrew application GeckoOS, which can launch a game with cheat codes enabled. We'll show you what you need to do to enable cheat codes in your games. The Occarina application used to enable cheat codes, but its functionality has been folded into GeckoOS. Prepare Your Wii to Run Cheats Before you can enable cheats on your homebrew Wii, you need to choose a method for creating the GCT cheat files that GeckoOS needs. There are three choices: Accio Hacks is a Wii homebrew application that allows you to download and manage cheats directly from your Wii. It has some limitations and sometimes fails to connect to the Gecko cheats database, but when it works it's the simplest approach.Online GCT Creator can be accessed from the Gecko Codes website. It's more flexible than Accio Hacks but requires you to manually copy your cheat file to your SD card.Gecko Cheat Code Manager is a PC application that lets you work with text files downloaded from the Gecko Codes website. It's the most flexible and powerful of the Wii cheat code managers but it's also the least convenient to use. Locate Your Cheat File You can locate cheats on the Gecko Codes website. You may find multiple listings for the same game. This is because games released for different regions can have different cheats. Lists of game cheats always include a game ID, the fourth letter of which indicates the region code. “E” is for the U.S., “J” is for Japan, “P” is for Europe. “A” indicates a code that works for all regions. GeckoOS won't recognize game IDs with the “A” code in them. You need to rename the file with the appropriate region letter. In some cases, cheats will work for other regions. For example, a Metroid: Other M cheat may only have a Japanese file, but when it's changed from “J” to “E” it works. To Get Cheats From the Gecko Codes Website If you want to find cheats on the Gecko Codes website, navigate to your game title by choosing the first letter of the game, then select it from the list. Either select GCT to open the Online GCT Creator or select txt to download a text file that can be used offline. To Get Cheats Using Accio Hacks If you want to use Accio Hacks, you need to connect your Wii to the internet. At the main menu, highlight “Accio Hacks/Manage Codes” and press the A button. Navigate to the first letter of your game. You’ll see a “Channel Select” menu, where you can choose the format of the game you want (choices include Wii, WiiWare, VC Arcade, Wii Channels, GameCube, etc.). Highlight the channel you want and press A. Now choose the first letter of the game you are looking for and press A. Highlight “Accio Hacks” and press A. After the file is downloaded you will be returned to the game list. Press the B button to back out. You will now see your game’s cheat file listed. Highlight it and press A. Navigate to the first letter of your game. You’ll see a “Channel Select” menu, where you can choose the format of the game you want (choices include Wii, WiiWare, VC Arcade, Wii Channels, GameCube, etc.). Highlight the channel you want and press A. Now choose the first letter of the game you are looking for and press A. Highlight “Accio Hacks” and press A. After the file is downloaded you will be returned to the game list. Press the B button to back out. You will now see your game’s cheat file listed. Highlight it and press A. Create a GCT File: Select, Edit, and Save Your Cheats After finding the cheat file for your game, you need to select the particular cheats you want to enable (invincibility, increased speed, all weapons, etc.) and save them into a “GCT” file that can be read by GeckoOS. This can be done through Accio Cheats, the Online GCT Creator, or the Gecko Cheat Code Manager. While the interfaces for each are different, the basics are the same. Each cheat code is made up of sets of alphanumeric characters, for example, “205AF7C4 4182000C.” In some cases, some numbers are strings of Xs which must be replaced with the appropriate alphanumeric string. Xs are used when there is more than one option; a comment in, above, or below the cheat tells you what values can replace the Xs. The Online GCT Creator and the Gecko Cheat Code Manager both allow you to add more cheat codes. Option 1: Create a GCT File Using Accio Hacks Pressing the + button brings up an explanation of Accio Hacks’ controls at any time. To create a GCT file using Accio Hacks: Once you highlight the cheat file for your game and press A, you should see a list of all the available cheats. Highlight each one you want and press A to add them. If you need to edit a cheat code press 1. Pressing 2 shows you comments for that code (which are also displayed if you press 1.) Once you select the cheats you want, hit the B button. You're given a choice of saving or not saving the file. Go ahead and save it. Afterward, keep pressing the B button until you get to the main menu. Highlight Exit to HBC. It's possible to use TXT files downloaded from the Gecko Codes website with Accio Hacks (this is useful if it's failing to connect with the Gecko database, or if your Wii is not connected to the internet). You simply need to put the file in the correct folder on your SD card. The formula is SD:\codes\X\L\GAMEID.txt, with X indicating the channel letter (which can be seen in the Accio main menu after each selection) and L indicating the first letter of the game title. Now it's time to launch your game. Option 2: Create a GCT File Using Online GCT Creator To create a GCT file with Online GCT Creator: Locate your game cheat file and select GCT. You should see a text box with all the codes listed. Select Add codes. This brings up the list of codes with checkboxes next to each one. Pick the codes you want, editing them if necessary. If you found any codes elsewhere, you can select Add more codes and enter them into the text box, then select Add codes. Once you select your codes, click Download GCT. Save your GCT file to the “/codes/” folder on the SD card you use for Wii homebrew, creating the folder if it doesn’t already exist. Now it's time to launch your game. Option 3: Create a GCT File Using Gecko Cheat Code Manager To create a GCT file using Gecko's cheat code manager: Start the manager. Select File > Open TXT file. Open the text file you downloaded from the Gecko Codes website. You should see a list of cheats in the left-hand column with a checkbox next to each one. Check the box for each cheat you want and edit any that need editing. Select Export to GCT. Save your GCT file to the “/codes/” folder on the SD card you use for Wii homebrew, creating the folder if it doesn’t already exist. Now it's time to launch your game. Load the Cheat and Run the Game Now that you have your GCT file, it's time to load the cheat and start up the game. Put the game disk in your Wii console, start Gecko OS, then launch the game. At a certain point, GeckoOS will tell you it's looking for cheat codes for the disk’s game ID. If it doesn’t find any, then you’ve done something wrong. In that case, check your SD’s /codes/ folder in WiiXplorer or with your PC and make sure you have a GCT file there with the appropriate game ID. Gecko will briefly display the game’s ID code before loading the game. If GeckoOS does find the appropriate GCT file, it will load it automatically and you can cheat to your heart’s content. If you want to stop cheating, exit the game, then either run it directly through the main Wii menu, turn off SD cheats in the GeckoOS config options, delete the cheat file from the SD:/codes/ folder, or simply re-edit the GCT file in the way you created it, but unselect all cheats and overwrite the existing file.
