KIM-1 to COSMAC Elf Conversion — Sort Of

In the mid-1970s, if you had your own computer, you probably built it. If you had a lot of money and considerable building skill, you could make an Altair 8800 for about $395 — better than the $650 to have it built. However, cheaper alternatives were not far behind.

In 1976, Popular Electronics published plans for a computer called the COSMAC Elf which you could build for under $100, and much less if you had a good junk box. The design was simple enough that you could build it on a piece of perf board or using wire wrap. We …read more

Completely Owning the Dreamcast Add-on You Never Had

If you’ve got a SEGA Dreamcast kicking around in a closet somewhere, and you still have the underutilized add-on Visual Memory Unit (VMU), you’re in for a treat today. If not, but you enjoy incredibly detailed hacks into the depths of slightly aged silicon, you’ll be even more excited. Because [Dmitry Grinberg] has a VMU hack that will awe you with its completeness. With all the bits in place, the hacking tally is a new MAME emulator, an IDA plugin, a never-before ROM dump, and an emulator for an ARM chip that doesn’t exist, running Flappy Bird. All in a …read more

Hackaday Prize Entry: Gaming Done Tiny with Keymu

The world’s tiniest Game Boy Color, introduced at the 2016 Hackaday SuperConference, is a work of art. This microscopic game console inspired [c.invent] to create how own gaming handheld. His Keymu project on hackaday.io describes an open source, keychain-sized gaming handheld that its builder claims is really the world’s tiniest. How did he make it smaller? It’s a miniature Game Boy Advance SP, and it folds up in a handy clamshell case.

While he’s a Pi fan, [c.invent] felt the Pi Zero was too big and clunky for what he had in mind–a keychain-sized handheld. Only the Intel Edison was …read more

Discontinued Nintendo Consoles and Raspberry Pis

Nintendo has discontinued a Classic gaming console. It’s a pity, yes, but with the release of Nintendo’s new gaming console, they probably have bigger fish to fry. That doesn’t mean these discontinued Nintendo consoles will die a slow, miserable death locked away in a closet; at least one of them will live on with the heart of a Raspberry Pi.

This is a project [Liam] has been working on since 2012, just after he got the first edition of the Raspberry Pi. While some people were figuring out how to stuff the Pi inside a Nintendo Entertainment System or a …read more

The Best Pi Emulation Console You Can Build

By far the most popular use for a Raspberry Pi is an emulation console. For an educational device, that’s fine – someone needs to teach kids how to plug a USB cable into a device and follow RetroPi tutorials on the Internet. These emulation consoles usually have one significant drawback: they’re ugly, with wires spilling everywhere. Instead of downloading a 3D printed Pi enclosure shaped like a Super Nintendo, [depthperfection] designed his own. It looks great, and doesn’t have a donglepocalypse hanging out the back.

The biggest factor in building an enclosure for a Pi Zero is how to add …read more

Raspberry Pi-Based Game Boy Emulator

The most popular use for a Raspberry Pi, by far, is video game emulation. We see this in many, many forms from 3D printed Raspberry Pi cases resembling the original Nintendo Entertainment System to 3D printed Raspberry Pi cases resembling Super Nintendos. There’s a lot of variety out there for Raspberry Pi emulation, but [moosepr] is taking it to the next level. He’s building the smallest Pi emulation build we’ve ever seen.

This build is based on the Pi Zero and a 2.2″ (0.56 dm) ili9341 TFT display. This display has a resolution of 240×320 pixels, which is close enough …read more
