Yes, Of Couse Someone Shot the Eclipse on a Game Boy Camera

This one shouldn’t surprise us, but there is something particularly enjoyable about seeing the total eclipse of the Sun through a Game Boy camera.

The Game Boy got its camera accessory back in 1998 when CCD-based cameras with poor resolution were just becoming widely available to the public. This camera can capture 128×112 pixel images in the four value grey scale for which the handheld is so loved.

Having taken part in eclipse mania ourselves we can tell you that unless you did some serious research and prep for photographing the thing, this makes as much sense as pulling out …read more

Using a Logic Analyzer to Generate Screenshots from a Game Boy

Wouldn’t you like to go back to a dead handheld and extract the proof of your 90s-era high scores? Of course you would.

[svendahlstrand] bought his first logic analyzer, a Logic 8 from Saleae and decided to play around with an old Game Boy. He opened up the handheld with a tri-point screwdriver and hooked six wires up to the LCD data bus, generating screen shots from the logged data. He got screens from Solomon’s Club, Mole Mania, Kid Dracula, and more.

The first few attempts were fraught with mishap as [sven] worked to figure out the settings of his …read more

Writing a New Game for the Game Boy Color

If you’re bored with the Game Boy Color’s offerings, it’s understandable: it’s been around for nearly 20 years, and doesn’t get a lot of new releases these days. [Antonio Niño Díaz] spent over a year coding a game for the GBC: µCity, a Sims City style game. He designed the graphics and even wrote his own music.

[Antonio] did all the programming in Assembly Language, creating modules for managing traffic and the power grid, building creation and destruction, as well as disaster simulations. He has extensive notes in his GitHub page detailing each module and describing how it all works …read more

Game Boy Mod Uses Raspberry Pi Compute Module 3

[inches] wanted the power of a Raspberry Pi 3 in a form factor closer to the Pi Zero for a Game Boy mod. This led him to design a custom PCB to interface with one of the less popular items in the Raspberry Pi line: the Compute Module 3. A hardware comparison between the three platforms is available here.

After correcting some minor issues, it booted correctly on the first try. The final result is slightly larger than a Raspberry Pi Zero, but significantly smaller than the Raspberry Pi 3, and fits perfectly inside the Game Boy for a clean …read more

Neural Nets And Game Boy Cameras

Released in 1998, the Game Boy camera was perhaps the first digital camera many young hackers got their hands on. Around the time Sony Mavica cameras were shoving VGA resolution pictures onto floppy drives, the Game Boy camera was snapping 256×224 resolution pictures and displaying them on a 190×144 resolution display. The picture quality was terrible, but [Roland Meertens] recently had an idea. Why not use neural networks to turn these Game Boy Camera pictures into photorealistic images?

Neural networks, deep learning, machine learning, or whatever other buzzwords we’re using require training data. In this case, the training data would …read more

Anti-Emulation Tricks on GBA-Ported NES Games

Emulation is a difficult thing to do, particularly when you’re trying to emulate a complex platform like a game console, with little to no public documentation available. Often, you’ll have to figure things out by brute force and dumb luck, and from time to time everything will come unstuck when a random piece of software throws up an edge case that brings everything screeching to a halt.

The Classic NES series was a handful of Nintendo Entertainment System games ported to the Game Boy Advance in the early 2000s. What makes them unique is a series of deliberately obtuse programming …read more

Pi Zero Transforms to Game Boy

[GreatScott] bought a Game Boy case. Normally, you’d assume you wanted this to repair a damaged Game Boy, but in this case [GreatScott] used a Pi Zero and some 3D printing to build a game system into the tiny box. You can see some videos, below.

Two interesting parts of the project are the source of the LCD display (a rearview camera screen) and the selection of batteries. Lithium ion batteries are all the rage. But if you watch the news, you know there are some safety issues with using the batteries, especially if you use them improperly. [GreatScott] decided …read more

DIY Coprocessors For The Game Boy Color

Back in the olden days, when video games still came on cartridges, the engineers and programmers making these carts had a lot of options. One of the most inventive, brilliant, and interesting cartridges to come out of the 90s was Star Fox for the Super Nintendo. Star Fox featured a coprocessor chip, the Super FX, that was effectively a GPU used to draw polygons in the frame buffer. Without this, Star Fox wouldn’t be 3D, Yoshi’s Island wouldn’t be as cute, and there wouldn’t be an always-on processor in your computer with the potential to spy on everything you do. …read more
