Original Gameboy Gets Stuffed Full Of Cool Parts

Raspberry Pi Gameboy

One day at Good Will, [microbyter] came across an original Gameboy for $5. Who reading this post wouldn’t jump on a deal like that? [microbyter] was a little disappointed when he got home and found out that this retro portable did not work. He tried to revive it but it was a lost cause. To turn lemons into lemonade, the Gameboy was gutted and rebuilt into a pretty amazing project.

Looking at the modified and unmodified units, it is extremely obvious that there is a new LCD screen. It measures 3.5″ on the diagonal and is way larger than the 2.6″ of the original screen. Plus, it can display colors unlike the monochrome original. Flipping the unit over will show a couple of buttons have been added to the battery compartment door to act as shoulder buttons.

The brains of the project is a Raspberry Pi running Retropie video game system emulation software which will emulate a bunch of consoles, including the original Gameboy. The video is sent to the LCD screen via the composite video output. The Pi’s headphone jack is connected to a small audio amplifier that powers the original speaker that still resides in the stock location. Connecting the controller buttons got a little more complicated since the original board was removed. Luckily there is a replacement board available for just this type of project that bolts into the stock location, allows the use of the original iconic buttons and has easily accessible solder points. This board is wired up to the Pi’s GPIO pins.

Pokemon Artificial Intelligence Is Smarter Than You

Pokemon Artificial Intellegence

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.

Twitch Plays Pokémon: Better than Prime Time TV

Twitch_plays_pokemon_animated

What do you get when you put together a classic Game Boy game, some glue code, a streaming video website and 1 internet? Twitch Plays Pokémon (TPP), a social experiment where thousands of people “cooperatively” play a game of Pokémon Red/Blue. TPP was created by an anonymous Australian programmer who enjoyed the SaltyBet interactive channel on twitch.tv. Rather than use SaltyBet’s method of having users interact via an external website, [TPP's creator] decided to use twitch’s own IRC based chat servers. Starting with VisualBoyAdvance, a popular C/C++ based Game Boy emulator, [TPP's creator] began building the system. [TPP's creator] went with python to create the web-to-emulator interface. A JavaScript app displays the live moves on the right side of the screen.

Gameplay is simple – users type their command (Up, Down, A, B) into their IRC or web client. In the original configuration, commands were processed in the order they arrived at the game. The system worked until the whole thing went viral. With thousands of people entering commands at any given time, poor “RED” would often be found spinning in place, or doing other odd things. The effect is so compelling that even [Randal Munroe] has written an XKCD entry about it. To help the players get through some of the tricky parts of the game, [TPP's creator] added a game mode selection. Users can play in “Democracy” where the system takes votes for several seconds, then issues the highest voted command. The original anything goes game mode was renamed “Anarchy”. Switching from one mode to the other is determined by the users themselves in real-time.

[Devon], one of our readers, has been busy as well. He’s written up a tutorial on turning a Raspberry Pi into a dedicated TPP viewer. We’d love to see a TPP battlestation – a Game Boy modified to display TPP, as well as send commands to the IRC servers when buttons are pressed. Who will be the first reader to knock that hack out?

The BitBox Console Gets Upgraded

BitBox Rev2

The Bitbox, an open source game console, has received a number of updates in the past couple of months. Last time we covered this DIY console, [Makapuf] had just managed to get the first revision to run a simple game. The second revision will increase the colors to 32k, add another channel of sound for stereo, switch controllers from PS2 to USB, and add support for Olimex’s UEXT expansion devices.

While the hardware upgrades are impressive, there’s been a lot of work on the Bitbox software as well. A new game demo called Fire was created as a set of tutorials to help people start developing for the console. There’s also a BitBoy, a GameBoy emulator for the Bitbox. BitBoy is a ported version of gnuboy for the ARM Cortex-M4 processor that powers the Bitbox. It successfully emulates a number of commercial GameBoy ROMs.

We’re looking forward to seeing what’s next for the Bitbox. After the break, check out a video of BitBoy running on the Bitbox.

The PiBoy

piboy

What do you do with a broken Gameboy, a 3″ LCD, a pile of wires, a USB SNES controller, a 32gb SD card, and a Raspberry Pi? You make a pocket emulator, of course!

[Anton] decided he wanted to build an emulator awhile ago. He had a few specific goals in mind: it had to be hand-held, portable, child safe, and usable without a keyboard. He started by stripping the broken Gameboy down to its external shell, then removing all of the internal plastic mounting features with a hot soldering iron. Next was the challenge of fitting everything into the case and powering it. Because his 3″ LCD runs off 12V, [Anton] needed a way to get 5V to the Pi. Lucky for him, it turned out that his LCD’s controller board had a 5V test point/expansion pin-out!

From there it was just a matter of reusing the original Gameboy’s speaker, closing up the case, and loading the emulator! As always, there’s a demo video after the break.

Another way to break out dual pin headers

[Uwe] wrote in to share his technique for breaking out dual pin headers. He uses two single pin headers, a piece of protoboard, and a dual row pin socket to make an adapter. This is removable where the other method we saw this week was not.

Web-based slide show hack

Wanting to use an old Android tablet as a digital picture frame, [Gordon] coded up a simple way to use an HTML page to scan your picture directories to feed a rotating background image.

The simplest hot plate

For his chemistry experiments [Charlie] is using a plain old clothes iron for a hot plate. he simply clamps it upside down to the bench. It doesn’t have any stirring abilities, but we already have an old iron in the shop which we use for toner transfer so we’ll have to keep this in mind if we ever need to heat chemicals (might be a good way to warm etchant).

A charging VU meter

This Cambrionix series8 universal charger has columns of LEDs that are animated when a device is charging. [Steve Tyson] works for the company and has had some fun messing with the firmware. He’s showing off the display as a VU meter.

Game Boy knockoff teardown

This wide-form-factor Game Boy is a knockoff from way back when the original system hit the market. You won’t want to miss this lengthy post that takes a look at what’s inside. [Thanks Neil]

Here’s another “useless machine” variant.  The trick to this one is that it has dual “fingers” and can work either way. Which way it turns off is selectable via a switch on the side, and the fingers can both be turned on to “fight” each other. Check out the video here.

This video depicts the assembly of a Gameboy MAME-style cabinet. For those wanting to try something like this, this video may fill you in on some of the required assembly techniques, such as how to put decals on the side of your cabinet.

This video featuring the “Autonomous Ultimate Wall-E” shows this robot’s navigational skills around the house.  Additionally, it has some nicely actuated arms.

The Verbalizer is a microphone designed to be used with Google’s voice search. It’s also designed with Arduino compatibility in mind and is open-source. Could be a good tool for your next hack.

These clever multimeter probes were built using pogo pins used in electrical test equipment. The springs inside of these pins help keep them planted firmly on the test point in question and reportedly gives a very good connection.
