Tiny Game Boy (That Plays Witcher 3) And Other Things That Blew My Mind

November 7, 2016 by Mike Szczys 48 Comments

For years Sprite_TM has been my favorite hacker, and yet he continues to have an uncanny ability to blow my mind with the hacks that he pulls off even though I’m ready for it. This weekend at the Hackaday SuperConference he threw down an amazing talk on his tiny, scratch-built, full-operational Game Boy. He stole the badge hacking show with a Rick Roll, disassembled the crypto challenge in one hour by cutting right to the final answer, and managed to be everywhere at once. You’re a wizard ~~Harry~~ Sprite!

Here’s what’s crazy: these are the antics of just one person of hundreds who I found equally amazing at the conference. It feels impossible to convey to you the absolute sincerity I have when I say that SuperCon was far and away the best conference I’ve ever been to or have even heard about. It managed to outpace any hyperbole I constructed leading up to the weekend. This morning felt like I was waking up from a dream and desperately wanted to fall asleep again.

Emulating A GameBoy Advance Inside Of A Gameboy Advance

November 3, 2016 by Gerrit Coetzee 18 Comments

[Ryzee119]’s GBA might not look so different at first glance. The screen is way better than you remember, but that may just be your memory playing tricks on you. The sound comes out of the speakers. It feels the right weight. It runs off AA batteries. Heck, even the buttons feel right.

It’s not until you notice that it really shouldn’t be playing any games without a cartridge inserted that you know something is not right in the Mushroom Kingdom. When you look inside you see the edge of a Raspberry Pi Zero instead of the card edge connector you expected.

It took a lot of work for [Ryzee119] to convert a dead, water damaged, GBA to a thriving emulation station based around a Pi Zero. The first step was desolder the components he couldn’t find anywhere else. The LR buttons, the potentiometer, and even the headphone jack. The famously hard to see screen, of course, had to go. It was replaced by a nice TFT. Also, the original speaker was too corroded from the water and he sourced a replacement.

Next he took a good photo of the GBA’s circuit board. We wonder if he used the scanner method mentioned in the comments of this article? He spent a lot of time in Dassault’s DraftSight, a 2D CAD program, outlining the board. Then, after thoroughly verifying the size of the board for the Nth time he imported the outlines to EagleCAD.

He managed to cram quite a bit onto the board while remaining inside the GBA’s original envelope. The switches, potentiometer, and jack went back to their original locations. Impressively, he made his own pad traces for the A, B, and D-Pad buttons. The mod even handles slowly decreasing battery voltages better than the original.

In the end it all snaps together nicely. He’s configured it to boot into the emulator right at start-up. If you’d like one for yourself, all his files are open source.

Simple Game Boy IPhone Mod Is Simple

October 21, 2016 by Richard Baguley 10 Comments

We’ve featured the work of [Modpurist] before, but his latest hack is wonderful in its simplicity. He wanted to create a more authentic Game Boy feel on his iPhone, so he printed out and stuck a skin on the front that makes it look like a Game Boy. Or rather, a Phone Boy, as the form factor is a bit different.

By measuring out the on-screen buttons and using light photo paper, he was able to have buttons on the skin as well: the touch screen still works through it. You can download his printable templates… and the finishing touch is a similar print for the back of the phone to gives that genuine Game Boy feel. Okay, feel is not the right term since the classic d-pad and red buttons are still just capacitive and have no throw. But this is a clever step in a fun direction.

Check out his other hacks while you are at it, including the Game Boy Fridge.

Game Pie Advance Brings Retro Gaming To Your Fingertips

September 3, 2016 by James Hobson 13 Comments

We love our Game Boy and RetroPie mods here at Hackaday because the Raspberry Pi Zero has made it easier than ever to carry a pocket full of classic games. [Ed Mandy] continues this great tradition by turning a matte black Game Boy Advance into a RetroPie handheld.

Details are scant on how [Mandy] built his Game Pi Advance, but we can glean a few details from the blog post and video. A Raspberry Pi Zero running RetroPie appears to be piggybacking on a custom PCB that slots neatly into the GBA case. This provides easy access to the Pi Zero’s USB and micro HDMI via the cartridge slot to connect to an external screen, as well as a second controller to get some co-op NES and SNES action on. It’s worth noting here that [Mandy] has foregone adding X and Y buttons in the current version.

Fly With A Game Boy Classic

August 21, 2016 by Jenny List 16 Comments

How many grown-up hardware hackers whiled away their youth playing Tetris or Mario on their Game Boy? Fond memories for many, but unless you are lucky your Game Boy will probably be long gone. Not for [Gautier Hattenberger] though, he had an unexpected find at his parents’ house; his Game Boy Classic, unloved and forgotten for all those years. Fortunately for us his first thought was whether he could use it as a controller for a drone, and better still he’s shared his work for all of us to see.

Back in the day a would-be Game Boy hacker would have been deterred by Nintendo’s legal defences against game piracy, but with the benefit of a couple of decades the handheld console’s hardware is now an open book. Unfortunately for [Gautier], he seems to be the first to use one as a flight controller, so he had to plough his own furrow. His Game Boy Game Link serial port feeds an Arduino/FTDI combination that converts Game Link to USB, which is then sent to his laptop on which a small piece of software converts them to commands for the drone through the Paparazzi UAV framework.

All his code is in a GitHub repository, and he’s posted a video of his work which you can see below the break. For a child of the early ’90s, the mere thought that their handheld console could do this would have been mindblowing!

Madison Maker Faire

May 15, 2016 by Mike Szczys 14 Comments

Saturday was the first Madison Mini Maker Faire. In this case, it’s Madison, Wisconsin (sorry Madison, SD I didn’t mean to get your hopes up) where I live. Of course I’m not the only crazy hardware hacker in the area. As soon as I got there I almost tripped over Ben Heckendorn who also lives in the area.

Check out that incredible Giant Game Boy the he was exhibiting. Okay, you think to yourself: Raspberry Pi and an LCD. Wrong! He’s actually using an FPGA to drive the LCD. Even cooler, it’s using an original Game Boy brain board, which the FPGA is connected to in order to translate the handheld’s LCD connector signals to work with the big LCD.

GameGirl: A Better Portable Raspberry Pi

April 17, 2016 by Brian Benchoff 8 Comments

For better or worse, the most popular use for the Raspberry Pi – by far – is media centers and retro game consoles. No, the great unwashed masses aren’t developing Linux drivers for their Pi peripherals, and very few people are tackling bare metal ARM programming. That doesn’t mean creating a handheld console based on the Pi isn’t a worthy pursuit.

For their entry for the 2016 Hackaday Prize, [David] and [Jean-André] are building a portable Pi console that’s much better than an old Bondo-encrusted Game Boy enclosure stuffed with hot glue and wires. They’re doing this project the right way with a hardware accelerated display, custom software, and a high quality case.

[David] is in charge of the hardware, and that means making a very, very small handheld console. The design of this GameGirl is extremely similar to the old-school Game Boy Pocket (or Game Boy Light). There’s a D-pad, four buttons, select, start, and two ‘shoulder’ buttons on the back. The build is based on the Raspberry Pi Zero, and thanks to the Pi’s standard 40-pin header, [David] is able to configure the display to use an RGB565 DPI interface. This means the display is stupidly cheap while still leaving a few GPIO pins left over for the SPI, buttons, backlight, and PWM audio.

[Jean-André] is the other half of the team, and his contributions to open source software make him exceptionally qualified for this project. He’s the main developer for Lakka, a DIY retro emulation console, and the #5 RetroArch contributor. No, this project isn’t using RetroPie – and there’s a reason for that. Emulator hackers are spending a lot of time optimizing emulators for the Raspberry Pi, only because of RetroPi. If these emulator hackers spent their time optimizing for an API like LibRetro, you could eventually play a working version of Pilotwings 64 on the Raspberry Pi and every other platform LibRetro is available for. All the effort that goes into making a game work with a Raspberry Pi is effort that goes into making that game work for the PSP, Wii, iOS, and a PC. Yes, its philosophical pissing in the wind while saying, ‘this is what the community should do’; this is open source software, after all.

With the right ideas going into the hardware and software, [David] and [Jean-André] have an amazing project on their hands. It’s one of the most popular entries and are near the top of the charts in the community voting bootstrap effort where every like on a project gets the team a dollar for their project. GameGirl is shaping up to be a great project, and we can’t wait to see the it in action.
