The Arduboy is a Kickstarter backed, 8 bit video game console that mimics the look of a very tiny Nintendo Gameboy. The Arduboy Classic is actually using the case, button and LCD screen from a classic Game Boy.
[uXe] is using the same brains, an ATMEGA32U4, along with a 328 as a co-processor to handle the classic “creme-n-spinich” gameboy screen. 2K of dual port ram acts as a buffer between the two micro-controllers meaning they can not only run while not being in lock step with eachother, but that each micro can read or write to the ram at the same time.
Currently the whole setup is spread out on a breadboard while all the interfacing is worked out, but it is working quite well. Future plans are to make a drop in motherboard replacement for the classic game system, and there is ample room for all the new electronics on the original footprint.
If you’re unfamiliar with the Arduboy project, check out our interview with it’s creator, [Kevin Bates]. That and the demo of [uXe’s] hack based on the project are both found after the break.

[Garrett Greenwood] plays Smash Brothers, and apparently quite seriously. So seriously that he needed to modify his controller with five Neopixels so that it flashed different color animations according to the combo he’s playing on the controller; tailored to match the colors of the moves of his favorite character, naturally.
All of this happens with an ATtiny85 as the brains, which we find quite ambitious. Indeed, [Garrett] started out thinking he could simply read each of the inputs from the controller directly into the microcontroller at the heart of the whole thing, but then counted up how many wires that would be, and looked at how many pins he had free (six), and thought up a better solution.
[Garrett]’s routine instead reads the single line that the Gamecube controller uses to send back to the console. The protocol is well understood, using long-short and short-long signals to encode bits. The only trick is that each bit is sent in four microseconds, so the decoding routine has to be fairly speedy. To make it work he had to do quite a bit of work. More about that, and the demo video, after the break.

With dozens of powerful single board Linux computers available, you would think the time-tested practice of turning vintage video game consoles would be a lost art. Emulators are available for everything, and these tiny Linux boxes are smaller than the original circuitry found in these old consoles. [Chris], one of the best console modders out there, is still pumping out projects. His latest is a portable N64, and it’s exactly what we’ve come to expect from one of the trade’s masters.
We’ve seen dozens of Nintendo 64s modded into battery-powered handhelds over the years, and [Chris]’ latest project follows the familiar format: remove the PCB from the console, add a screen, some buttons, and a battery, and wrap everything up in a nice case. It’s the last part of the build – the case – that is interesting here. The case was fabricated using a combination of 3D printing CNC machining.
The enclosure for this project was initially printed in PLA, the parts glued together and finally filled for a nice, smooth finish. [Chris] says PLA was a bad choice – the low melting point means the heat from milling the face plate gums up the piece. In the future, he’ll still be using printed parts for enclosures, but for precision work he’ll move over to milling polystyrene sheets.
With the case completed, a few heat sinks were added to the biggest chips on the board, new button breakout board milled, and a custom audio amp laid out. The result is a beautifully crafted portable N64 that is far classier and more substantial than any emulator could ever pull off.
[Chris] put together a video walkthrough of his build. You can check that out below.

If your living room entertainment area is not home to a Raspberry Pi based retro game console, you no longer have any excuses. Break out your soldering iron and volt/ohm meter and preheat the 3d printer, because you will not be able to resist making one of the best retro game consoles we’ve ever seen – The Nin10do.
It’s creator is [TheDanielSpies]. Not only did he make the thing from scratch, he’s done an extraordinary job documenting all the build details, making it easier than ever to follow in his footsteps and make one of your own. He designed the case in Autodesk and printed it out with XT Co-polyester filament. He uses a Raspi of course, along with an ATX Raspi board from Low Power Labs to make the power cycling easier. There’s even a little stepper that opens and closes a cover that hides the four USB ports for controllers. Everything is tied together with Python, making the project super easy to modify and customize to your liking.
All code, schematics and .stl files are available on his github. It even has its own Facebook page! Be sure to check out the vast array of videos to help you along with your build.

Before the days of the RetroPie project, video game clones were all the rage. Early video game systems were relatively easy to duplicate and, as a result, many third-party consoles that could play official games were fairly common. [19RSN007] was recently handed one of these clones, and he took some pretty great strides to get this device working again.
The device in question looks like a Sega Genesis, at least until you look closely. The cartridge slot isn’t quite right and the buttons are also a little bit amiss. It turns out this is a Famicom (NES) clone that just looks like a Sega… and it’s in a terrible state. After a little bit of cleaning, the device still wasn’t producing any good video, and a closer inspection revealed that the NOAC (NES-on-a-Chip) wasn’t working.
Luckily, [19RSN007] had a spare chip and was able to swap it out. The fun didn’t stop there though, as he had to go about reverse-engineering this chip pin-by-pin until he got everything sorted out. His work has paid off though, and now he has a video game system that will thoroughly confuse anyone who happens to glance at it. He’s done a few other clone repairs as well which are worth checking out, and if you need to make your own NES cartridges as well, we’ve got you covered there, too.
Minecraft wizard, and record holder for the Super Mario World speedrun [SethBling] is experimenting with machine learning. He built a program that will get Mario through an entire level of Super Mario World – Donut Plains 1 – using neural networks and genetic algorithms.
A neural network simply takes an input, in this case a small graphic representing the sprites in the game it’s playing, sends that input through a series of artificial neurons, and turns that into commands for the controller. It’s an exceedingly simple neural network – the network that can get Mario through an entire level is less than a dozen neurons – but with enough training, even simple networks can accomplish very complex tasks.
To train the network, or weighting the connections between inputs, neurons, and outputs, [SethBling] is using an evolutionary algorithm. This algorithm first generates a few random neural networks, watches Mario’s progress across Donut Plains 1, and assigns a fitness value to each net. The best networks of each generation are combined, and the process continues for the next generation. It took 34 generations before MarI/O could finish the level without dying.
A few members of the Internet’s peanut gallery have pointed to a paper/YouTube video by [Tom Murphy] that generalized a completely different technique to play a whole bunch of different NES games. While both [SethBling]’s and [Tom Murphy]’s algorithms use certain variables to determine its own success, [Tom Murphy]’s technique works nearly automatically; it will play about as well as the training data it is given. [SethBling]’s algorithm requires no training data – that’s the entire point of using a genetic algorithm.

Feeling nostalgic? Miss the solid feel of an original Nintendo Game Boy? You could smash a window with one and keep playing Pokemon the whole time! Well, [Raz] was, and he built what might just be the biggest Gameboy ever. Gameboy XXL: The Texas Edition.
Actually, it was commissioned for a Belgian music festival called Nintendoom — picture video game music + rave. Anyway, the organizer thought it would be so cool to have a giant functional Game Boy, so [Raz] got to work. He made it out of 10 square meters of 3mm thick MDF, which he laser cut into shape at the Brussels FabLab. The electronics inside consist of a 19″ LCD monitor, a Raspberry Pi, and a few jumbo size buttons.
It’s pretty freaking awesome. It runs Retropie which allows you to play pretty much whatever game you want. Check it out after the break.
