Who out there hasn’t angrily thrown a game controller across the room after continually getting killed by some stupid game-controlled villain? That is such a bummer! You probably wished there was some way to ‘just get past that point’. To take a step in that direction, [Ben] created an Artificial Intelligence program that will win at Pokemon Blue for Game Boy Advance.
The game is run in a Game Boy Advance emulator known as Visual Boy Tracer, which itself is a modified version of the most common GBA emulator, Visual Boy Advance. What sets Visual Boy Advance apart from the rest is that it has a memory dump feature which allows the user to send both the RAM and the ROM out of the emulator. The RAM holds all values currently needed by the emulator, this includes everything from text arrow flash times to details about currently battling Pokemon to the players position in the currently loaded map. The memory dump feature is key to allow the AI to understand what is happening in the game.

While they’re probably rare as hen’s teeth in the US, there have been a few major stores around the world that have started rolling out electronic shelf labels for every item in the store. These labels ensure every item on a shelf has the same price as what’s in the store’s computer, and they’re all controlled by an infrared transceiver hanging on the store’s ceiling. After studying one of these base stations, [furrtek] realized they’re wide open if you have the right equipment. The right equipment, it turns out, is a Game Boy Color.
The shelf labels in question are controlled by a base station with a decidedly non-standard carrier frequency and a proprietary protocol. IR driver chips found in phones are too slow to communicate with these labels, and old PDAs like Palm Pilots, Zauruses, and Pocket PCs only have an IrDA chip. There is one device that has an active development scene and an IR LED connected directly to a CPU pin, though, so [furrtek] started tinkering around with the hardware.
The Game Boy needed to be overclocked to get the right carrier frequency of 1.25 MHz. With a proof of concept already developed on a FPGA board, [furrtek] started coding for the Game Boy, developing an interface that allows him to change the ‘pages’ of these electronic labels, or display customized data on a particular label.
There’s also a much, much more facepalming implication of this build: these electronic labels’ firmware is able to be updated through IR. All [furrtek] needs is the development tools for the uC inside one of these labels.
There’s a great video [furrtek] put together going over this one. Check that out below.

If you’re playing along with Twitch Plays Pokemon, you might as well do it the right way: with the smallest Game Boy ever, the Game Boy Micro. [Anton] needed a battery replacement for this awesome, discontinued, and still inexplicably expensive console and found one in a rechargeable 9V Lithium battery. You get two replacement cells out of each 9V battery, and a bit more capacity as well.
Every garden needs garden lights, right? What does every garden light need? A robot, of course. These quadruped “Toro-bots” react to passersby by brightening the light or moving out of the way. It’s supposed to be for a garden that takes care of itself, but we’re struggling to figure out how lights will do that.
Flexiable 3D prints are all the rage and now resin 3D printers are joining the fray. The folks at Maker Juice have introduced SubFlex, a flexible UV-curing resin. The usual resins, while very strong, are rock solid. The new SubFlex flexible resins are very bendable in thin sections and in thicker pieces something like hard rubber. We’re thinking custom tank treads.
Remember this post where car thieves were using a mysterious black box to unlock cars? Looks like those black boxes have moved from LA to Chicago, and there’s still no idea how they work.
Have a Google Glass? Can you get us on the list? [Noé] and [Pedro] made a 3D printed Google Glass adapter for those of us with four eyes.
[Rodot] wrote in to tell us about the Gamebuino, a very nicely designed and easily reproducible version of his handheld Arduino gaming console. We originally featured [Rodot's] Arduino based gaming console over a year ago.
With the Gamebuino, you too can build your own games and gaming hardware around the Arduino. While there is a lot of information currently missing from the site’s Wiki, such as the layout and game code, [Rodot] plans on making everything open source. The console includes a rechargeable lithium battery, a micro SD card, and I2C expansion connectors. This is one project to keep an eye (and two hands) on, especially since a full game library is going to be provided, letting you easily create your own games. See what the console can do in the demo video after the break.
It would be amazing so see some old Game Boy games ported to run on the Arduino, or maybe one of our readers can make an Game Boy emulator for the Arduino!

[Adan] had an old Game Boy sitting around, and without anything better to do decided to investigate the link cable protocol with a microcontroller. He had a Stellaris Launchpad for the task, but initially had no project in mind. What he came up for this adventure in serial protocols is a first gen Pokemon trade spoofer that allows him to obtain pokemon without having two Game Boys, or for the weird ones out there, “friends.”
The Game Boy link protocol is extremely well documented, so getting data from the Game Boy to the Launchpad was as simple as a soldering up an old link cable connector to a piece of perf board. After figuring out the electronics, [Adan] looked at what happened when two Pokemon games tried to trade pokemon. When two Game Boys are linked, there are two in-game options: trade or battle. Looking at the data coming after the ‘trade’ option, [Adan] found something that could possibly be the data structure of the Pokemon being sent. He reverse-engineered this all by himself before discovering this is also well documented.
Bringing everything together, [Adan] figured out how to trade non-existent Pokemon with a small dev board. Right now he’s only transmitting Pokemon that are hard-coded on the Launchpad, but it’s very possible to transmit the Pokemon values in real-time over USB.
Thanks [Dan] for sending this in, and no, we don’t know what’s up with the influx of Pokemon posts over the last week. Video of the spoof below.

With WiFi, Wonder Trade, and new Pokemon that are freakin’ keys, you’d think the latest generation of everyone’s reason to own a Nintendo portable is where all the action is, right? Apparently not, because Pokemon Blue just became a development tool for the Game Boy.
Despite all notions of sanity, this isn’t the first time we’ve seen someone program a Game Boy from inside a first generation Pokemon game. Around this time last year, [bortreb] posted a tool assisted run that deposited and threw away in-game items to write to the Game Boy’s RAM. Using this method, [bortreb] was able to craft a chiptune version of the My Little Pony theme inside Pokemon Yellow.
A year later, [TheZZAZZGlitch] has gone above and beyond what [bortreb] did. Instead of a tool assisted run, [ZZAZZ]‘s hack can be done manually on a real Game Boy. This trick works by using an underflow glitch to obtain item ’8F’ in the player’s inventory. Here’s a great tutorial for doing that. With this 8F item, a few items can be tossed and a ‘programming’ mode is activated where code can be written to RAM by walking to an X Y position on the map, using the 8F item, and writing a program byte by byte.
The maximum amount of code that can be written to the Game Boy RAM is 254 bytes, just large enough for [TheZZAZZGlitch] to write a very, very simple version of Akranoid, Breakout, or one-player Pong. Not much, but very, very impressive.
Video of [ZZAZZ] ‘jailbreaking’ his copy of Pokemon Blue available below.

Synth heads and electronic music aficionados the world over love a good rackmount synth. These days, though, synthesis tends more toward small, digital, and ‘retro’ rather than the monstrous hulking behemoths of the 60s and 70s. [gieskes] might be ahead of the curve, here, as he’s built a Game Boy module for his eurorack synthesizer.
The software running on [gieskes]‘s Game Boy is the venerable Little Sound DJ (LSDJ), the last word in creating chiptunes on everyone’s favorite 8-bit handheld. As with any proper Game Boy used in chiptunes, there are a few modifications to the 1980s era hardware. [gieskes] tapped into the cartridge connector with a ‘repeat’ signal that provides slowed down, noisy signals for LSDJ. There’s also pitch control via CV, and the audio output is brought up to 10Vpp
In the video below, you can see [gieskes]‘ euroboy in action with a few Doepfer synth modules. There’s also a very cool pulse generator made from an old hard drive in there, so it’s certainly worth the watch.
