Game Boy-Style Camera For Playdate

July 20, 2023 by Bryan Cockfield No comments

The Game Boy Camera, while perhaps not the most technologically advanced piece of equipment, left a huge mark on video game and electronics culture. The grayscale photographs are still highly prized, and there are an untold number of projects which interface with original hardware to download authentic Game Boy Camera pictures to modern computers. There are others that look to recreate the feel and style of these images, and the latest comes to us on a Game Boy-like platform as well, the Playdate.

[t0mg] is the creator of this project, utilizing a OV7670 camera module sending data to a Teensy 4.1 which interfaces with the Playdate via USB. The images recorded on the Playdate are 1-bit, slightly different than the 2-bit images the Game Boy Camera was capable of. The case of the camera also physically matches up well with the small console, using magnets to secure it to the device either in normal camera mode, in reverse for selfie mode, and can also support the console in “cover” mode as a way of storing the console to protect the screen. A companion application needs to run on the Playdate to get this all up and running, but with that and a battery plenty of retro-style images are ready to be captured.

All of the source for this project is available on the project’s GitHub page for anyone ready to experience some nostalgia or just experiment with a small camera like this. It’s a clean build that takes advantage of the Playdate’s open-source nature, through which we’ve seen the console turned into a typewriter and inspire other builds like this one-off handheld with a crank-style controller.

Little Twitter Game Boy Won’t Work Now The API Is Dead

April 19, 2023 by Lewin Day 13 Comments

Twitter, like many social networks, used to feature a useful API. This let people do fun things like create toasters that could automatically post breaderly updates, or even load Twitter posts on machines that couldn’t handle full-fat websites. That API is now history, but [NEKOPLA] used it for a cute Game Boy-like Twitter device in its dying days earlier this year.

Swap out the TW BOY for a smartphone and this photo wouldn’t be nearly as good.

The “TW BOY”, as it is known, runs on a Raspberry Pi Zero 2 W, which includes a WiFi chip on board for easy internet connectivity. A Python script was charged with fetching Tweets for viewing using the now-dead Twitter API. Dithering was used to display color images on the 320×240 monochrome screen. Everything was wrapped up in a tidy 3D-printed housing to complete the look. The device uses two action buttons, and four directional buttons for navigation. It’s the layout popularized by the original Game Boy, and it looks super cute here, too.

The project was built as [NEKOPLA] has a penchant for single-use devices, due to their solitary focuses on doing one thing well. We can appreciate that ethos, and we love the final product, even if Twitter decreed it would no longer work. (Time to move on to Mastodon?) More images after the break.

Classic Film Camera Goes Digital With Game Boy Tech

April 5, 2023 by Robin Kearey 8 Comments

Despite having been technologically obsolete for a decade or two, analog photography is still practiced by hobbyists and artists to achieve a particular aesthetic. One might imagine a similar thing happening with early digital cameras, and indeed it has: the Game Boy Camera has seen use in dozens of projects. [Michael Fitzmayer] however decided to combine the worlds of analog and early digital photography by equipping a Holga with the image sensor from a Game Boy Camera.

The Holga, if you’re not familiar, is a cheap film camera from the 1980s that has achieved something of a cult following among retro-photography enthusiasts. By equipping it with the sensor from what was one of the first mass-market digital cameras, [Michael] has created a rather unusual digital point-and-shoot. The user interface is as simple as can be: a single button to take a photo, and nothing else. There’s no screen to check your work — just as with film, you’ll have to wait for the pictures to come back from the lab.

The sensor used in the Game Boy Camera is a Mitsubishi M64282FP, which is a 128 x 128 pixel monochrome CMOS unit. [Michael] hooked it up to an STM32F401 microcontroller, which reads out the sensor data and stores it on an SD card in the form of a bitmap image.

With no film roll present, the Holga has plenty of space for all the electronics and a battery. The original lens turned out to be a poor fit for the image sensor, but with a bit of tweaking the Game Boy optics fit in its place without significantly altering the camera’s appearance.

[Michael] helpfully documented the design process and shared all source code on his GitHub page. Holgas shouldn’t be hard to find to find, but if none are available in your area you can just roll your own. The Game Boy Camera is actually one of the most versatile cameras out there, having been used for everything from video conferencing to astrophotography.

Creating A Game Boy ROM From Pictures

March 23, 2023 by Bryan Cockfield 22 Comments

There are very few legal ways of obtaining ROM files for video games, and Nintendo’s lawyers are extremely keen on at least reminding you of the fact that you need to own the game cart before obtaining the ROM. With cart in hand, though, most will grab a cart reader to download the game files. While this is a tried-and-true method, for GameBoy games this extra piece of hardware isn’t strictly required. [Travis Goodspeed] is here to show us a method of obtaining ROM files from photographs of the game itself.

Bits can be manually edited to fix detection errors.

Of course, the chips inside the game cart will need to be decapped in order to obtain the pictures, and the pictures will need to be of high quality in order to grab the information. [Travis] is more than capable of this task in his home lab, but some work is still required after this step.

The individual bits in the Game Boy cartridges are created by metal vias on the chip, which are extremely small, but still visible under a microscope. He also has a CAD program that he developed to take this visual information and extract the data from it, which creates a ROM file that’s just as good as any obtained with a cart reader.

This might end up being slightly more work especially if you have to decap the chips and take the photographs yourself, but it’s nonetheless a clever way of obtaining ROM files due to this quirk of Game Boy technology. Encoding data into physical hardware like this is also an excellent way of ensuring that it doesn’t degrade over time. Here are some other methods for long-term data storage.

Breadboarding A Game Boy From Scratch

February 15, 2023 by Lewin Day 17 Comments

The original Nintendo Game Boy is a stout piece of hardware in a solid plastic enclosure. [Raphael Stäbler] recreated the popular handheld on a breadboard instead, in a fully-functional way, to boot.

[Raphael]’s build doesn’t rely on a real Game Boy CPU or components. Instead it’s emulated with the aid of a Teensy 4.1 microcontroller. [Raphael] coded up an emulator from scratch, instruction by instruction, something he’s documented on his own blog. The Teensy is placed on a breadboard, and hooked up with a series of 8 buttons to serve as the controls. Audio output is via a LM386 acting as a simple audio amp, hooked up with an original Game Boy speaker for more authentic sound. Display is thanks to a FT81x display driver running a small LCD. Games are loaded via an SD card formatted in the FAT32 file system.

While it’s not as ergonomic as the original Nintendo console, it works, and works well! It’s an impressive project to see the Game Boy recreated from scratch inside a powerful microcontroller. We’ve seen other projects go to similar lengths before. Video after the break.

DIY Game Boy Games Make The Perfect Christmas Gift

January 12, 2023 by Lewin Day 3 Comments

Sometimes, the best gift is the one you make yourself. [Pigeonaut] decided to whip up a few Game Boy games of their very own creation to gift to the special people in their life.

The games were crafted using a platform called GB Studio. It’s a tool that allows the drag-and-drop creation of games for the Game Boy and Game Boy Color handhelds. It’s capable of creating ROM files to run in an emulator, within a web page, or they can be flashed to a cartridge and played on real Nintendo hardware.

For the full effect, [Pigeonaut] went with the latter method. Four games were created: Phantom Shock, Climbing Mount Crymore, Cozy Cat Cafe, and A Tiny Hike. Each was flashed onto a real cart and given a high-quality label to make a lovely tangible gift. Upon gifting, [Pigeonaut]’s friends and partner were able to play their way through their personalized titles on a GameCube running the Game Boy Player accessory.

It’s hard to imagine a more touching gift than a personal game crafted from the ground up. Getting to play it on a real Nintendo is even better, and we’ve seen hardware that can achieve that before.
