Slack Updated November 14, 2019 Consoles & PCs Xbox Buyer's Guide Tweet Share Email Modding a Wii isn't as hard as you'd think. Modding, or modifying, a game system to gain access to older games and software not intended for the version of the Wii you have, used to involve lots of work. You had to open up a game system, insert chips or other various items, tinker with the internals and deal with the fact that going online or playing games with certain anti-mod software was no longer available to a system modified in such a way. And then there was the amount of risk for those not well-versed in physically modding a system; hard modding, or modifying the system hardware, could cause irreversible damage if done wrong, and the loss of money (and even your system) to untrustworthy people that offer the service.

Unlike the Xbox or PS2, modding a Wii doesn't require any physical tinkering and costs way less than one would think. In fact, modding a Wii doesn't take more than using an SD card, the same type of card that a digital camera uses. Wiis have SD slots to expand the amount of space it can hold and to allow a user to post pictures from a digital camera to the Wii. But crafty hackers have found that more than simply photos can be sent to the Wii in this fashion: hack files. Many that have hacked their Wiis are able to play backups, DVDs, youtube videos and more on the system. The methods out there are great but we've seen the best success using the flash memory on the SD rather than an in case modding. You only need to purchase a few things to do this, things you may already have. HDSD Cards and an SD Reader An SD card is the same as the thin small chip that is used inside of a digital camera. Small and light, they come in as small as 2GB and much larger. The Wii has both a slot for an SD card in the front of the unit almost resembling a memory card slot. The SD card slot was intended for saving small things like on system pictures and uploading pictures from your camera. But if you add in an SD Reader for your computer, and then that tiny SD card can become a small boot up disc of programs to download to the Wii. Downloading programs such as BootMii and NeoGamma on your PC, then transferring them onto an SD through the reader is almost the equivalent of making a floppy full of cracking software just for your Wii. The upside about using a card in this way as it doesn't have to be formatted for the Wii. So you could technically store Wii files and computer files onto them. Getting the Right Model Number/Version So you have an SD reader and some HDSD cards. You have a bunch of programs you want to test on your Wii. Before you jump for joy, look up that Wii's model number and update version. If it's not version 4.1 (or lower) or worse, has been fully updated with all current Wii updates, then most likely you will not be able to soft mod it. (Soft-modding is what we've been talking about, meaning we aren't modifying any hardware, just letting the software hack files do it all.) Keep in mind the soft modding methods out there will void your warranty with Nintendo and that if you send in your Wii for repair, Nintendo can and will replace anything not up to date. This includes hardware and software patches. Now, why would Nintendo do this? Because every update is a hotfix or backdoor fix. They basically are being nice and saying, 'stop tinkering with our system'. So if your Wii has a major issue, try to find a technical friend first. Only send your unit in as a last resort. Portable Hard Drives Eventually, that SD card will be full of hacks, backup games and the like. HDSD cards only hold but so much. This is where a portable Hard Drive can come in handy. A 100+ HD can store many backups and files and can easily be loaded and removed. Finding More Info About Modding Your Wii In this article we really only touched the surface of modding a Wii (or any console for that matter), there are much more detailed articles out there. Our Nintendo Guide Site has a slew of info on modding, a guide to homebrew, installing the Homebrew Channel on your Wii, and many more of the advantages of having a modded system, we suggest looking there as your next step. And from there, there are always going to be tons of in-depth articles on Google, Yahoo, or your favorite search engines. You just need to know some of the right terms to look for, which we've given a good start here.
