Mods Keep The WaveBird Kicking In The Switch Era

April 13, 2019 by Tom Nardi 11 Comments

Nintendo made some questionable decisions during the early 2000’s, but developing the WaveBird certainly wasn’t one of them. Years before wireless controllers were the standard on home game consoles, the WaveBird gave GameCube owners a glimpse into the future. It managed to deliver lag-free gaming without resorting to easily-blocked infrared, and had a battery life and range long enough that there was really no downside to cutting the cord aside from the lack of rumble support.

In fact, the WaveBird was such a good controller that some fans just can’t put the thing down even in 2019. [Bill Paxton] loves his so much that he decided to modify it so he could use it on Nintendo’s latest money printing machine, the Switch, without having to fiddle with any adapters. While he was at it, he decided to fix the only serious drawback of the controller and hack in some rumble motors; arguably making his re-imagined WaveBird superior in just about every way to the original.

It might be counter-intuitive, but the trick here is that [Bill] actually took the internals from a standard wired GameCube controller and fitted it all into the case for the WaveBird. That’s how he got the rumble support back, but where does the signature wireless capability come from?

For that, he took apart a “GBros. Wireless Adapter” from 8BitDo. This gadget is intended to let you use your existing GameCube controllers on the Switch wirelessly, so all he had to do was shove its PCB inside the controller and wire it directly to the pads on the controller’s board. Thankfully, the WaveBird was rather husky to begin with, so there’s enough space inside to add all the extra hardware without much fuss.

Between modifications like this and efforts to reverse engineer the controller’s wireless protocol, hackers aren’t about to let this revolutionary accessory go gently into that good night. You might see a GameCube slaughtered for a meme, but WaveBirds never die.

Farming Items With RasPi-Modified Joycons

April 2, 2019 by Lewin Day 6 Comments

The Pokémon games have delighted legions of Nintendo gamers over the years, and show no signs of slowing down any time soon. Despite its popularity, there are certain aspects of the games that are unarguably about simply grinding your way to success. For [Mori Bellamy], this simply wouldn’t do – yet their thirst for gold bottlecaps was insatiable. What to do? Automate it, of course.

The first step was to hack the Joycons from the Nintendo Switch. A DG333A analog switch IC was hooked up to the buttons inside, and controlled by the GPIO pins of a Raspberry PI. The joystick was then controlled with an MCP4725 DAC, allowing the system to fully emulate control inputs to the console.

With the console now under control by the Raspberry Pi, the next step was to add intelligence. Google’s Tesseract OCR platform was combined with a helping of Python code. This allows the script to read dialog boxes from the game, and use this data to determine which buttons to press to farm items.

[Mori] has provided the code on GitHub for others to use, noting that it should be generalizable to other games with a little work. Fundamentally, the underlying hardware could readily be repurposed to other controllers, too. There’s plenty of other ways to automate the drudgery of gaming, even if you have to use a touch screen. Video after the break.

Eight Player GameCube Adapter Is Ready For Smash

November 2, 2018 by Tom Nardi 4 Comments

With the release of Smash Ultimate fast approaching for the Nintendo Switch, [Patrick Hess] wanted to get ahead of the game and make sure his squad had the equipment they’d need. Namely, support for the GameCube controllers that serious Smash Bros players demand. But it wasn’t enough to have one or two of them hooked up, or even four. Not even six GameCube controllers could satiate his desire. No, he needed to have support for eight simultaneous GameCube controllers, and he wanted to look good doing it too.

Enter his meticulously designed eight player GameCube to USB adapter. Made out of dual official Nintendo GameCube to USB adapters (intended for the Wii U) merged together in a 3D printed case, the final result looks like something that could earn the coveted Nintendo Seal of Approval. Or at least, something that might pop up on the import sites in the next month or two for a few bucks.

[Patrick] started the project by recreating the official adapter PCBs and their housings in 3D using a pair of calipers. After a couple of test prints to make sure he had all the dimensions right, he could then move on to designing his final enclosure knowing he had accurate data to model around.

In addition to the two adapter boards, there’s also a four port USB hub inside the device’s case. Each adapter has two USB leads, here shortened to fit inside the case, which connect up to the hub. The integrated hub allows connecting all eight GameCube controllers through only a single USB connection. All controllers worked as expected during intense testing on the Wii U’s version of Smash Bros, though at this point [Patrick] can only assume it will work when the Switch version is released.

If there’s a downside to this project, it’s that the design for the 3D printed case is so intricate that [Patrick] was only able to print it on a machine that supported water-soluble PVA supports. A somewhat tall order for the average hacker; it would be interesting to see if somebody could make a second pass on the enclosure that is geared more towards printability than aesthetics.

While the design of the GameCube controller remains somewhat controversial after all these years, there’s no denying it retains an impressive following. Whether turning them into USB devices, shrinking them to preposterously small dimensions, or just finding increasingly creative ways to use them on Nintendo’s latest console, hackers are definitely in love with the gonzo little controller that’s now pushing 20 years old.

Thinking Inside The (Cardboard) Box With Nintendo Labo Hacks

July 19, 2018 by Roger Cheng 2 Comments

Cardboard is one of the easiest ways to build something physical, far easier than the 3D printing and laser cutting we usually write about here. So when Nintendo released their Labo line of cardboard accessories, it doesn’t take a genius to predict the official product would be followed by a ton of user creations. Nintendo were smart enough to provide not only an internet forum for this creativity to gather, they also hold contests to highlight some of the best works.

The most impressive projects in the winner’s circle combined the one-of-a-kind cardboard creations with custom software written using Toy-Con Garage, the visual software development environment built into the Nintendo Switch console. Access to the garage is granted after a user runs through Nintendo Labo’s “Discover” activities, which walk the user behind the scenes of how their purchased Labo accessories work. This learning and discovery process thus also serves as an introductory programming tutorial, teaching its user how to create software to light up their custom cardboard creations.

It’s pretty cool that Nintendo opened up a bit of the mechanism behind Labo activities for users to create their own, but this is only a tiny subset of Nintendo Switch functionality. We have different hacks for different folks. Some of us enjoy reverse engineering details of how those little Joy-Cons work. Others hack up something to avoid a game puzzle that’s more frustrating than fun. And then there are those who are not satisfied until they have broken completely outside the sandbox.

Nintendo Switch Gets Internal Trinket Hardmod

July 1, 2018 by Tom Nardi 51 Comments

If you haven’t been following the Nintendo Switch hacking scene, the short version of the story is that a vulnerability was discovered that allows executing code on all versions of the Switch hardware and operating system. In fact, it’s believed that the only way to stop this vulnerability from being exploited is for Nintendo to release a new revision of the hardware. Presumably there are a lot of sad faces in the House of Mario right about now, but it’s good news for us peons who dream of actually controlling the devices we purchase.

To run your own code on Nintendo’s latest and greatest, you must first put it into recovery mode by shorting out two pins in the controller connector, and then use either a computer or a microcontroller connected to the system’s USB port to preform the exploit and execute the binary payload. It’s relatively easy, but something you need to do every time you shut the system down. But if you’re willing to install an Adafruit Trinket M0 inside your Nintendo Switch, you can make things a little easier.

Stemming from work done by [atlas44] and [noemu], the final iteration of this mod was created by [Quantum-cross]. The general idea is to strip down the Trinket M0 board to as small as possible by removing the USB port and a few capacitors, and then install it inside the Switch’s case. By wiring it up to power, the back of the USB-C connector, and the controller connector, the Trinket can interact with all the key components involved in the exploit.

You can even use the Switch’s USB port to update the firmware on the Trinket to load different payloads, though in his walkthrough video after the break, [xboxexpert] mentions eventually this won’t really be necessary as the homebrew software environment on the Switch matures. Indeed, there will almost certainly come a time when performing this exploit on every boot of the system will be made unnecessary, rendering this modification obsolete. But until then, this is a pretty slick way of getting your feet wet in the world of Switch hacking.

It was only six months or so back that we were reading about the first steps towards running arbitrary code on the Nintendo Switch, and just a few months prior to that we saw people experimenting with controlling the system with a microcontroller.

Reverse Engineering Nintendo Labo Waveform Cards

April 26, 2018 by Richard Baguley 29 Comments

The Nintendo Switch portable gaming system is heavily locked down to prevent hacking, but the Labo add-on looks like it might be a different matter. The Labo is a series of add-on devices made of cardboard that does things like turn the Switch into a musical keyboard that plays a waveform on a card that you slot in. [Hunter Irving] decided to try a bit of reverse engineering on these cards to see if he could 3D print his own. Spoilers: he could.

[Hunter] started by taking one of the cards that come with the Labo and looking at the layout. These cards are, like the rest of the Labo, very simple: they are just shaped pieces of card that fit into the back of the keyboard add-on. When you press a button, the Switch camera reads the card to create the waveform. So, the process involved figuring out the required dimensions of the card to create a template. [Hunter] then created simple waveforms (square, sine, sawtooth) in Inkscape, and used this to create a 3D printable waveform card. A quick bit of 3D printing later, he had several cards ready, and these worked without problems. As well as the synthetic waveforms, he tried real ones, such as an organ, taking the waveform shape from the zoomed-in sample and using that to print. This post describes the process nicely and offers downloads of 9 sample cards and a template to create your own.

We suspect that this is only scratching the surface of what can be done with the Switch, Labo, and some ingenuity. Unlike the Switch itself, the Labo seems to be built for hacking, using simple, easy to use components to create surprisingly complex mechanisms that could be adapted for any number of purposes.

We’re sure this isn’t the only Labo hack we’ll be covering over the coming year. Not sure what all the fuss is about? Read our reporting on its arrival.

LEGO Meets Nintendo Switch

April 4, 2018 by Tom Nardi 3 Comments

As you probably know, the Nintendo Switch is the incredibly popular console of the moment. You of course also know that LEGO has been popular since the beginning of recorded history. So it was only a matter of time before somebody decided that these two titans of youthful entertainment needed to combine up like some kind of money-printing Voltron. You know, for science.

[Vimal Patel], a known master of all things plastic brick related, decided to take up the challenge with a few experimental LEGO accessories for the Switch. These add-ons are largely designed to make playing the Switch a bit more comfortable, but represent an interesting first step to more complex hardware modifications down the road.

The key to these experiments are a set of 3D printed rails which allow you to attach standard LEGO parts to the Switch. With the rails installed, [Vimal] demonstrates a simple “kick stand” which improves the system’s stability when not being used in handheld mode.

A few different steering wheel modifications are also demonstrated, which use an impressive bit of engineering to move the controller’s analog stick left and right with rotational input on the wheel. Both variations are shown in-use with Mario Kart, and seem to do the job.

It will be interesting to see what kind of projects will be made possible at the intersection of Switch and LEGO when Nintendo Labo goes live later this month.
