Turning Corroded, Bug-Loving WiiMotes Into A Working One

August 22, 2026 by 3 Comments

A time-honored tradition in the electronics repair business is to make many into one, specifically a stack of broken devices into one that works. So too with a triplet of heavily corroded and bug-infested WiiMote controllers that [eWastelander] dug out of a box of e-waste. After suffering abuse like leaving in leaky alkaline cells, bugs and general corrosion the task was to see whether at least one working WiiMote could be assembled from these three. (Video, embedded below.)

Adding to the fun was that the PCBs in these WiiMotes spanned at least two hardware revisions, and on one board the battery corrosion had caused an IC to fall off. After an initial assessment, neutralizing the battery acid and a deep clean of all the disassembled parts, it was time to give it a shot at reassembly into something resembling a Wii controller you could use and even want to touch without washing your hands afterwards.

Ultimately at least one working WiiMote was put together, with still an open question whether the remaining two  units in much worse conditions could be revived in some way. An interesting idea here is to use the WiiMote shells for a custom OpenMote board, which replaces the guts with an ESP32-S3-based system for more general non-Wii things around the house.

Joy-Cons Plus WiiMotes Make For Switch 2 Wii-Cons

August 18, 2026 by 5 Comments

As popular as the Nintendo Switch and its sequel are, it’s hard to argue that its click-on Joy-Con controllers are ergonomic, barring you having very uniquely shaped hands. This thought and a stack of Wii controllers led [KOUZEX] to the mad project of merging Joy-Cons and WiiMotes into what can affectionately be called Wii-Cons, or perhaps JoyMotes.

Suffice it to say that it’s not a very clean or easy mod, and you could definitely make the point that a custom PCB and 3D-printed shell would  have been a lot easier. Making space for the Joy-Con’s side rail, thumb stick and PCB without simply tossing the WiiMote’s PCB was a tough ask, and these are two WiiMotes that will never connect to a Wii again.

With the WiiMote-shaped Joy-Cons working pretty well after all that work, the issue of remapping Joy-Con buttons that have no match on WiiMotes was probably the biggest headache. Here having said custom version could be rather helpful to have more control over the button layout, also to not have to keep harvesting the dwindling supply of WiiMotes to make WiiCons. It might even be possible to keep all the WiiMote functionality that way, to really blow people’s minds when you use your fancy Joy-Cons to next play a game on an original Wii.

Digging Into The Twilight Hack That Brought Us Wii Homebrew

April 11, 2026 by 40 Comments

With each new game console, there’s an effort to get around whatever restrictions exist to run your own software on it. In the case of the Nintendo Wii, the system was cracked through one of its most popular games — The Legend of Zelda: Twilight Princess. How this hack works was recently covered in detail by [Skawo].

The key for this ‘Twilight Hack‘ is to use a modified game save that allows you to run arbitrary code from an SD card, something which was first patched out of the Wii firmware with version 3.3. As shown in the video using the source code, the basic concept is that the name of Link’s horse in the game is changed in the save file to be longer than the allocated buffer, which leads to a buffer overflow that can be used to reach the application loader code.

Interestingly, while the horse’s name can only be 8 characters long, and the buffer is 16 bytes (due to ShiftJIS two-byte encoding), the save file loading code allocates no less than 100 bytes, for some reason. Since the code uses strcpy() instead of strncpy() (or C11’s strncpy_s()), it will happily keep copying until it finds that magic 0x00 string terminator. Basically the horse can have any name that fits within the save file’s buffer, just with no null-byte until our specially crafted payload has been copied over.

Although it took Nintendo a few months to respond to this hack, eventually it was patched out in a rather brutal fashion by simply searching for and wiping any modified save files. Naturally this didn’t stop hackers from finding ways to circumvent this save file check, which led to more counter-fixes by Nintendo, which led to more exploits, ad nauseam.

Even with firmware update 4.0 finally sunsetting the Twilight Hack, hackers would keep finding more ways to get their previous Homebrew Channel installed, not to mention so that they could keep watching DVDs on a Wii.

You’ve All Seen A Hackintosh, But Have You Seen One On A Wii?

April 8, 2026 by 30 Comments

The Intel era of Apple Macs led to so-called “Hackintoshes”, more normal PCs running x86 MacOS X. Now Bryan Keller proves that a Hackintosh isn’t restricted to the x86 era, not by doing it with a modern ARM version, but by going back to PowerPC, and the Nintendo Wii.

The Wii can be thought of in hardware terms as not too far from a Mac G3 with a little less memory, having a PowerPC 750-family processor, a close relative as those in the first generation of MacOS X capable Macs. Since the roots of MacOS X are shared with its open-source equivalent Darwin, he reasons it should be possible to port just enough Darwin to the Wii to enable the closed-source OS X to run on top of it. He’s running OS X 10.0, the earliest version from 2001.

The write-up is a fascinating path through writing a bootloader and running a patched kernel that flashes the Wii LEDs, and then the process of making the Wii’s very different hardware from a Mac, accessible to the OS. It boots from an SD card and uses a framebuffer for display so perhaps it’s not as fast as you might hope, but he gets it working. Even for someone not versed in MacOS or the Wii, it’s a good write-up that makes its points accessible.

Something that makes us happy about this piece of work is its place in the greater picture, after all the Wii has found itself running classic MacOS too.

Ordering Pizza On The Nintendo Wii (Again)

January 22, 2026 by 4 Comments

The Nintendo Wii first launched in 2006, and quickly became a fixture in living rooms around the world. It offered motion-controlled bowling, some basic internet features, and a pretty decent Zelda game. On top of all that, though, you could also use it to order a pizza, as [Retro Game Attic] demonstrates.

The Wii used to organize different features of the console into “channels.” Way back in the day, you could install the Demae Channel on your Wii in Japan, which would let you order fast food from various outlets using the Demaecan service.

The Demae Channel service was discontinued in 2017. However, it has since been resurrected by WiiLink, which is a homebrew project which replicates the functionality of the original Nintendo WiiConnect 24 and Wi-Fi Connection servers. As it stands, you can load the WiiLink version of the Demae Channel (or Food Channel) on to your Wii, and use it to order pizza from your local Domino’s Pizza. It only works in the United States and Canada right now, and there are no other restaurants available, at least until further development is completed to add JustEat compatibility. It’s not entirely clear how much of the functionality was recreated from the original Demae Channel; what is clear is that plenty of custom development has been done on the WiiLink version to integrate it with modern delivery services.

What’s so exciting about this is how well it actually works. The app perfectly nails the classic Wii Channel visual style. It also seems to integrate well with the Domino’s API for digital orders, even displaying simple updates on holiday opening hours and order times. Pricing data and images of the pizzas are all available right in the app, and you can even make modifications. It might be a gimmick… but it actually works. Notably, though, the app avoids any stickiness with handling payment—thankfully, pay-on-delivery is still legitimate in the pizza world in 2026.

Will this revolutionize how you order pizza on a daily basis? Probably not. Is it one of the coolest Wii hacks we’ve seen in a while? Undeniably. Video after the break.

Yes, Gemini, A Wii Server Is Possible

October 2, 2025 by 21 Comments

When [Reit Tech] needed something to do with an old Nintendo Wii, he turned to Google. When the AI overview told him it could not be used as a server, he had his mission: prove that clanker wrong. It already runs Doom, so what else is there to do?

Of course should not that hard: Linux has been available on the Wii for years now. In fact there are several; he settles on “Arch, btw”, after trying Debian, Ubuntu, and even NetBSD. “Of course it runs NetBSD”– but NetBSD didn’t work with his USB network adapter, which is sadly as predictable as the hardware running NetBSD.

OK, it’s not vanilla Arch; it’s the Wii-Linux Continuation Project, based on ArchPOWER fork that compiles Arch for PPC. As the young YouTuber was surprised to discover, despite not being a PC or particularly powerful, the Wii has a PowerPC CPU. (He might be younger than the console, so we’ll give him a pass.) Wii-Linux couldn’t run the USB adapter either (appropriate apologies were offered to NetBSD), but it turns out the internal Ethernet adapter was available all along.

As a file server, python-based Copyparty worked flawlessly, but the rust-based Minecraft server he picked was not particularly usable. A little optimization would fix that, since you can serve Minecraft from an ESP32 and the Wii absolutely has more horsepower than that. Doubtless he could have loaded a web-server, and proved Google’s AI summary wrong, but the iPad-induced ADHD we all suffer from these days kicks in, so he settled for posting a screenshot of someone else’s blog, hosted on a Wii from NetBSD. So the LLM was wrong from the get-go, but the tour of “what home-brew loaded OSes still work in 2025” was certainly educational.

We could hunt that Wii-based blog down for you, but we’d be reluctant to link to it anyway: while the AI summary is wrong, and you can use the Wii as a server, that doesn’t mean it makes a good one. We’d don’t feel the need to inadvertently DDOS some poor unsuspecting shmuck’s Nintendo, so we’ll let you try and find it yourself.

Just be warned that all of this Wii hacking may not rest on the best of foundations. Continue reading “Yes, Gemini, A Wii Server Is Possible” →

An Open-Source Wii U Gamepad

May 19, 2025 by 8 Comments

Although Nintendo is mostly famous for making great games, they also have an infamous reputation for being highly litigious not only for reasonable qualms like outright piracy of their games, but additionally for more gray areas like homebrew development on their platforms or posting gameplay videos online. With that sort of reputation it’s not surprising that they don’t release open-source drivers for their platforms, especially those like the Wii U with unique controllers that are difficult to emulate. This Wii U gamepad emulator seeks to bridge that gap.

The major issue with the Wii U compared to other Nintendo platforms like the SNES or GameCube is that the controller looks like a standalone console and behaves similarly as well, with its own built-in screen. Buying replacement controllers for this unusual device isn’t straightforward either; outside of Japan Nintendo did not offer an easy path for consumers to buy controllers. This software suite, called Vanilla, aims to allow other non-Nintendo hardware to bridge this gap, bringing in support for things like the Steam Deck, the Nintendo Switch, various Linux devices, or Android smartphones which all have the touch screens required for Wii U controllers. The only other hardware requirement is that the device must support 802.11n 5 GHz Wi-Fi.

Although the Wii U was somewhat of a flop commercially, it seems to be experiencing a bit of a resurgence among collectors, retro gaming enthusiasts, and homebrew gaming developers as well. Many games were incredibly well made and are still experiencing continued life on the Switch, and plenty of gamers are looking for the original experience on the Wii U instead. If you’ve somehow found yourself in the opposite position of owning of a Wii U controller but not the console, though, you can still get all the Wii U functionality back with this console modification.

Thanks to [Kat] for the tip!
