World’s Smallest Wii Is Also World’s Worst

October 8, 2018 by Tom Nardi 14 Comments

As far as game consoles go, the Nintendo Wii was relatively small. Probably owing at least somewhat to the fact that it wasn’t a whole lot more than a slightly improved GameCube in a new case, but that’s another story entirely. So it’s not much of a surprise that people have modded Nintendo’s infamous money printing machine into handheld versions. But this…this is just something else.

We’re going to go out on a limb and say that this absolutely preposterous build by [Shank] which puts a fully functional Nintendo Wii into an Altoids tin wins the title of “World’s Smallest Wii”. We’re also going to put money on the fact that this record doesn’t get beaten because…well, come on. There’s a reason he’s named his diminutive creation the “Kill Mii”.

You’re probably wondering how this is possible. That’s an excellent question. As it turns out, hackers have discovered that you can cut off the majority of the Wii’s motherboard and still have a functioning system, albeit missing non-essential functions like the GameCube controller ports and SD card slot. From there, you just need to install a new firmware on the now heavily trimmed down Wii that tells it to ignore the fact it has no disc drive and load games as ISOs from an attached USB flash drive. That’s the high level summary anyway, the reality is that this a mod of crushing difficulty and should only be attempted by true masochists.

As for this particular build, [Shank] went all in and even relocated the Wii’s NAND chip to make everything fit inside the tin. There’s also custom PCBs which interface the Wii’s motherboard with the Nintendo 3DS sliders he’s using for control sticks. Underneath everything there’s a battery that can run the whole device for a grand total of about 10 minutes, but given the general shape of the “Kill Mii” and the fact that most of the buttons are tactile switches, that’s probably about as long as you’d want to play the thing anyway.

Yes, this is the worst Wii ever made. But that was also the point. In the words of the creator himself “This portable is not logical, comfortable, or practical. But it must be done… for the memes.” Truly an inspiration to us all.

Incidentally, this isn’t the first “trimmed” Wii portable we’ve seen; though that one was considerably more forgiving internally, and just a bit more practical.

Metroid, Zelda, And Castelvania Auto-Mapped With NES Emulation & Heuristics

August 30, 2018 by Lewin Day 11 Comments

The NES was one of the flagship consoles of the glorious era that was the 1980s. Many of the most popular games on the platform involved some sort of adventure through scrolling screens — Metroid, Super Mario, and Zelda all used this common technique. For many games, keeping track of the map was a huge chore and meant mapping by hand on graph paper or using the screenshots published in Nintendo Power magazine. These day’s there’s a better way. [Daniel] set out to automatically map these huge two-dimensional worlds, developing software he calls WideNES to do it.

WideNES is an add-on to [Daniel]’s own NES emulator, ANESE. As part of the emulator, WideNES can easily read the various registers of the NES’s Picture Processing Unit, or PPU. The registers of the PPU are used to control the display of the background and sprite layers of NES graphics, and by monitoring these, it is possible to detect and map out the display of levels in various NES games.

It’s an interesting piece of software that relies on a thorough understanding of the NES display hardware, as well as the implementation of some neat tricks to deal with edge cases such as vertical scrolling in The Legend of Zelda or room changes in games like Castlevania — the use of perceptual hashing is particularly genius. There’s source and more available on the project page, including a GitHub link, if you’re interested in getting down to brass tacks.

We’re impressed by the manner in which WideNES is able to so neatly map out these games of yesteryear, and can’t wait to see where the project goes next. [Daniel] notes that it should be possible to integrate into more popular emulators without too much trouble. If that’s not enough, check out this reverse-emulation Nintendo hack.

Using Modern Nintendo Controllers On The C64

August 23, 2018 by Tom Nardi 12 Comments

There are plenty of people out there who still enjoy playing games on vintage computers like the Commodore 64. But while they likely return to these classic games themselves out of a sense of nostalgia, the feeling doesn’t always extend to the hardware itself. For example, one can enjoy playing Impossible Mission without having to use a contemporary C64 joystick.

Thanks to an open source project developed by [Robert Grasböck], C64 owners who want to take advantage of the improvements made to gaming controllers in the nearly 40 years since the system’s release now have another option. Called Nunchuk64, it allows you to use various Nintendo controllers which make use of the Wii “Nunchuk” interface on original C64 hardware. This includes the controllers from the recent “Classic Edition” NES and SNES systems, which offer a decidedly retro feel with all the benefits of modern technology and construction techniques.

Both the hardware and software for Nunchuck64 are open source, and everything you need to build your own version is in the project’s repository. [Robert] even has assembly instructions, complete with images, which walk you through building your own copy of the hardware and flashing the firmware onto it. This is a nice touch that we very rarely see even in open source projects. The board is populated with a ATmega328P microcontroller and a handful of passive components, making assembly fairly straightforward assuming you are comfortable with SMD work.

Bringing more modern controllers to classic systems seems to be gaining popularity recently, within the last few months we’ve seen Xbox 360 controllers on the Nintendo 64, and newly manufactured pads for the Atari 5200.

PC In An SNES Case Is A Weirdly Perfect Fit

August 18, 2018 by Tom Nardi 20 Comments

For better or for worse, a considerable number of the projects we’ve seen here at Hackaday can be accurately summarized as: “Raspberry Pi put into something.” Which is hardly a surprise, the Pi is so tiny that it perfectly lends itself to getting grafted into unsuspecting pieces of consumer tech. But we see far fewer projects that manage to do the same trick with proper x86 PC hardware, but that’s not much of a surprise either given how much larger a motherboard and its components are.

So this PC built into a Super Nintendo case by [NoshBar] is something of a double rarity. Not only does it ditch the plodding Raspberry Pi for a Mini-ITX Intel i5 computer, but it manages to fit it all in so effortlessly that you might think the PAL SNES case was designed by a time traveler for this express purpose. The original power switch and status LED are functional, and you can even pop open the cart slot for some additional airflow.

[NoshBar] started by grinding off all the protruding bits on the inside of the SNES case with a Dremel, and then pushed some bolts through the bottom to serve as mounting posts for the ASUS H110T motherboard. With a low profile Noctua CPU cooler mounted on top, it fits perfectly within the console’s case. There was even enough room inside to add in a modified laptop charger to serve as the power supply.

To round out the build, [NoshBar] managed to get the original power slider on the top of the console to turn the PC on and off by gluing a spring-loaded button onto the side of the CPU cooler. In another fantastic stroke of luck, it lined up almost perfectly with where the power switch was on the original SNES board. Finally, the controller ports have been wired up as USB, complete with an adapter dongle.

[NoshBar] tells us the inspiration for sending this one in was the Xbox-turned-PC we recently covered, which readers might recall fought back quite a bit harder during its conversion.

Get Nostalgic With These GameCube Themed Joy-Cons

August 11, 2018 by Tom Nardi 9 Comments

There are a lot of good reasons to think fondly of the Nintendo GameCube. Metroid Prime and Rogue Leader knocked it out of the park. The Game Boy Player was cool. There’s even something to be said for having a convenient carrying handle on a system designed for couch multiplayer. But if you ask anyone who played Nintendo’s sixth generation console what part they missed the least, it would probably be the controller. With all the visual flair of a Little Tikes playset and ergonomics designed for an octopus, it’s a controller that works well for first-party Nintendo titles and little else.

So it’s probably for the best that these Switch Joy-Cons created by [Madmorda] focus on recreating the aesthetics of the GameCube controller for Nintendo’s latest money-printing machine rather than its feel. With a surprising amount of work required to create them, these definitely count as a labor of love by someone who yearns for the days when gaming was more…cubic.

To start with, nobody makes Joy-Con cases in that signature GameCube purple so [Madmorda] had to paint them herself. The longevity of a painted controller is somewhat debatable, but the finish certainly looks fantastic right now.

For the left analog stick [Madmorda] was able to use the cap from a real GameCube controller, which fit perfectly. Apparently, Nintendo has been pretty happy with their analog stick sizing decisions for the last two decades or so. The right analog stick was another story, however, and she had to cut the shaft down to size with a Dremel to get the cap to fit.

Finally, molds were made of the original face buttons, which were then used to cast new buttons with colored resin to match the GameCube color scheme. Since the original Switch buttons don’t have indented lettering to get picked up by the mold, she had to laser etch them. This little detail goes a long way to selling the overall look.

The final result looks great, and compared to previous attempts we’ve seen to bring some of that early 2000’s Nintendo style to the Switch, this one is certainly less destructive. Check them out in action after the break!

Find Your Level – Extracting NES Game Data Using Python

August 1, 2018 by Sven Gregori 8 Comments

Just this summer, the Nintendo Entertainment System had its 35th release anniversary, and even after years of discontinuation, it is still going strong in the hacker community. Exhibit A: [Matthew Earl]. For one of his upcoming projects, [Matthew] needed to get his hands on the background images of the NES classic Super Mario Bros. Instead of just getting some ready-rendered images and stitching them together, he decided to take care of the rendering himself, once he extracts the raw game data.

Since there is no official source code available for Super Mario Bros, [Matthew] used a disassembled version to get started looking for the image data. To avoid reading through thousands of lines of assembly code, and to also see what actually happens during execution, he wrapped the game’s ROM data into py65emu, a Python library emulating the 6502, the CPU that drives the NES. By adding a simple wrapper around the emulator’s memory handler that tracks reads on uninitialized data, [Matthew] managed to find out which parameters he needs to feed to the parser routine in order to get the image tile data. After an excursion into the Picture Processing Unit (PPU) and its memory arrangements, [Matthew] had everything he needed to create the Python script that will render the game background straight from its ROM data.

Even if extracting NES game data is not your thing, the emulator concept [Matthew] uses might be still worth a read. On the other hand, if you want to dig deeper into the NES, you should definitely have a look at emulating an SNES game on a NES, presented on the NES itself.

Add-On Board Brings Xbox 360 Controllers To N64

July 31, 2018 by Tom Nardi 22 Comments

Many of the games released on the Nintendo 64 have aged remarkably well, in fact a number of them are still considered must-play experiences to this day. But the years have not been so kind to the system’s signature controller. While the N64 arguably defined the console first person shooter (FPS) genre with games like “Goldeneye” and “Perfect Dark”, a modern gamer trying to play these classics with the preposterous combination of analog and digital inputs offered by the N64 controller is unlikely to get very far.

Of course, you could play N64 games in an emulator and use whatever controller you wish. But where’s the challenge in taking the easy way out? [Ryzee119] would much rather take the insanely complex route, and has recently completed work on an add-on board that let’s you use Xbox 360 wireless controllers on Nintendo’s 1996 console. He’s currently prepping schematics and firmware for public release, with the hope that support for additional USB controllers can be added by the community.

Nintendo historians may recall that the N64’s controllers had an expansion port on the bottom where you would connect such accessories as the “Rumble Pak” and “Controller Pak”. The former being an optional force feedback device, and the latter a rather oddly named memory card for early N64 games which didn’t feature cartridge saves. Only “90’s Kids” will recall the struggle of using the “Rumble Pak” when a game required the “Controller Pak” to save progress.

Thankfully [Ryzee119] has solved that problem by adding battery backed storage to his adapter along with some clever code which emulates the “Controller Pak”. Similarly, the “Rumble Pak” is emulated by the Xbox 360 controller’s built-in force feedback and a bit of software trickery. Specific button combinations allow for enabling and disabling the various virtual accessories on the fly.

But the best part of this modification might be how unobtrusive the whole thing is. Not only does it allow you to still use the original controllers and accessories if you wish, but it only requires soldering a handful of wires to the console’s motherboard. Thanks to the surprising amount of dead space inside the system’s case, it’s not even a challenge to fit the board inside. You do need to use the official USB Xbox 360 controller receiver, but even here [Ryzee119] opted to put a USB port on the board so you could just plug the thing in rather than having to cut the connector off and trying to solder it to the board yourself.

It probably won’t come as a surprise that this isn’t the first time [Ryzee119] has fiddled with the internals of a classic Nintendo system. We’ve previously covered his fantastic custom PCB to fit a Raspberry Pi Zero into a GameBoy Advance.
