It’s small, it’s blurry, but it’s working. Here’s a proof of concept for playing emulators on a Chromecast which uses the original Game Boy as an example.
This puts stars in our eyes about emulator hacks. We’d love to see this boiled down to smartphone and Chromecast as the two pieces of hardware, with the touchscreen as the gaming input.

Over at TI, the 2013 Intern Design Challenge is underway, an opportunity for the interns of TI to flex their engineering muscle for a few prizes and a chance to have their designs turned into actual products. We’re thinking [Max] might just pull this one out with his BeagleBone Gaming Cape, an add-on to the BeagleBone Black that turns this ARM-powered Linux board into a retro gaming system.
The build was inspired by [Max]’s earlier MSP430 Launchpad GamingPack, an add-on board for the Launchpad that put two NES controllers, a VGA out, and an FPGA to create a custom gaming console that’s up there with the brightest and best consoles of the 16-bit era. For the new BeagleBone-based build, [Max] eschewed off-board processing, but did manage to include a magnetometer/accelerometer and an audio codec IC to provide the best gaming experience for all those NES, Game Gear. Gameboy, GBA and Doom .wad games.
In addition to a fabulous piece of hardware, [Max] also has the case design down to a tee. He first printed out a dozen or so layers of his case, sandwiching the BeagleBone, his cape, battery holders, and LCD display. Once he knew the dimensions would work, he sent his files off to be laser cut out of a matte black delrin. The finished piece is a work of art, and considering how well everything goes together, we wouldn’t mind giving this new retro-gaming console a spin ourselves.
Seriously, the drawer pull on this Atari 2600 is not stock. Don’t they know this voids the warranty? The thing is, you won’t actually find any of the original internals anyway. When building this portable emulator housed in a 2600 case [Linear Nova] was careful to ensure that everything could be restored to its original condition (except for two hinges mounted on the back) sometime down the road. That’s a good goal to set for yourself. We think the build is the fun part of most projects and often wonder what to do with them when they’re done and our interest has waned.
A seven-inch LCD screen was attached to the underside of the lid using Velcro. When tilted up it’s at a nice viewing angle for the player. [Linear] prefers to use a Wii remote as the control this portable video game emulator. It connects to the Raspberry Pi over Bluetooth using a USB dongle. The advantage of this is that you just throw the remote inside the case too. For now there are two power cords, one for the RPi and the other for the LCD screen but he plans to add a power hub in the future to narrow this down to one. We wonder it that would also be a good time to add his own rechargeable battery pack option? There should be enough room for an RC style pack.
[Joe’s] wife grew up playing Sega games and he wanted to help her unwind by reliving the experience. Since the work computer she uses when travelling isn’t a good place to install emulators he built this plug-and-play emulator inside of a Sega controller.
We’ve seen this type of thing a few times before (even with XBMC in a SNES controller) but there is one thing we hadn’t thought of lately. Newer versions of Windows have auto-launch disabled for USB drives. But [Joe] knew that there were still some USB sticks that manage to auto-launch anyway so he researched how those work. It turns out that they have two partitions, one is formatted as a CDFS which looks like a CD-ROM to Windows and allows auto-launch. He used this method of partitioning a USB stick, storing the ROMs on the mass storage partition and the emulator and the CDFS partition. To finish the hack he cracked open the controller and found room for a USB hub and the PCB from the thumb drive.
If you still have cartridges lying around you can pull the ROMs off of them over USB.
The creator of this project started off with a 7″ tablet he received from a coworker. The screen was horribly smashed from one corner spreading out through the entire surface. But the hardware inside still worked, including the HDMI out port. He ended up transplanting the tablet hardware for use as an emulator.
After a bit of sizing up it was determined that the tablet hardware would fit inside the case of a broken NES. The battery would have been a tough fit, but this thing is always going to need to be connected to a television so there’s no need to work without mains power. The back plate was cut down to size and used as a try for mounting the motherboard in the case. Before that step he wired up a USB hub and mounted it so that two ports could be accessed through the original controller port openings.
There’s no details on the software used, but the final image in the gallery shows a game of Starfox being played.
You can look and look, but you won’t find a Super Nintendo inside of this retro gaming rig. [Webrow] is giving his vintage hardware a rest, and taking this all-in-one game emulator suitcase wherever he goes.
The machine at the heart of his build is of course a Raspberry Pi. You really can’t beat the ubiquitous board for cost, power, and hardware extensibility. An LCD panel from a broken laptop comes along for the ride having been mounted in the lid. For a long time there was no hope for reusing these panels, but [Webrow] found an adapter board (for nearly the same price as the RPi) which converts the DVI from the Pi to the LVDS needed by the screen. The connections and mounting scheme for the screen were where most of the project work was done. Connecting the controllers simply involved soldering some SNES controller sockets to an RPi breakout connector. We do have to compliment him on the red bezel which hides all of the power cords and other unsightly bits. The case look sturdy and ready to play!
This RFID card has a lot of nice features. But the one that stands out the most is the ability to learn the code from anther RFID tag or card.
You can see that the board includes an etched coil to interact with an RFID reader. This is the sole source of power for the device, letting it pick up enough induced current from the reader to power the PIC 12F683 seen on the upper left of the board. The underside of the PCB hosts just three components: an LED and two switches. One of the switches puts the device in learning mode. Just hold down that button as you move the board into the magnetic field of the reader. While in learning mode a second RFID tag is held up to the reader. It will identify itself and the emulator will capture the code sent during that interaction. This is all shown of in the video after the break. We wonder how hard it would be to make a version that can store several different codes selected by holding down a different button as the emulator is held up to the reader?
If you want to build your own card reader too here’s a project that does it from scratch.
