Hackaday Prize Entry: Dodo 6502 Game System

September 22, 2016 by 13 Comments

If you are a gamer of A Certain Age, it’s probable that you retain a soft spot for 8-bit computers and consoles of your youth. For a time when addictive gameplay came through the most minimal of graphics, and when gaming audio was the harshest of square waves rather than immersive soundscapes.

Does the previous paragraph sound familiar? Then we may just have the device for you. The Dodo is a handheld console that harks back to that era with a 6502 processor and a 128×64 pixel OLED screen. Games are loaded from plug-in EEPROM cartridges, and sounds are suitably period-digital square wave tones. It’s the brainchild of [Peter Noyes], and he says he will consider it complete when it sports a game fun enough to entertain his 4-year-old.

The prototype Dodo is a handheld form-factor made from two stacked PCBs. The upper one has the display and buttons while the lower has the classic 6502 and associated chipset in through-hole DIP format. A Game Boy Micro it ain’t, but miniaturization is not the name of the game with these consoles. Best of all though, all the console’s resources are available in a GitHub repository, so you can all have a play too.

The 6502 has featured in a huge number of projects here on Hackaday over the years. Now it’s turned up in the Hackaday Prize.

Game Pie Advance Brings Retro Gaming To Your Fingertips

September 3, 2016 by 13 Comments

We love our Game Boy and RetroPie mods here at Hackaday because the Raspberry Pi Zero has made it easier than ever to carry a pocket full of classic games. [Ed Mandy] continues this great tradition by turning a matte black Game Boy Advance into a RetroPie handheld.

Details are scant on how [Mandy] built his Game Pi Advance, but we can glean a few details from the blog post and video. A Raspberry Pi Zero running RetroPie appears to be piggybacking on a custom PCB that slots neatly into the GBA case. This provides easy access to the Pi Zero’s USB and micro HDMI via the cartridge slot to connect to an external screen, as well as a second controller to get some co-op NES and SNES action on. It’s worth noting here that [Mandy] has foregone adding X and Y buttons in the current version.

This NES Emulator Build Lets You Use Cartridges To Play Games

July 29, 2016 by 25 Comments

You may not remember this, but Nintendo hardware used to be a pretty big deal. The original Game Boy and NES both had remarkable industrial design that, like the Apple II and IBM Thinkpad, weren’t quite appreciated until many years after production ended. But, like many of you, [daftmike] had nostalgia-fueled memories of the NES experience still safely locked away.

Memories like lifting the cartridge door, blowing on the cartridge, and the feel of the cartridge clicking into place. So, understandably, reliving those experiences was a key part of [daftmike’s] Raspberry Pi-based NES build, though at 40% of the original size. He didn’t just want to experience the games of his youth, he wanted to experience the whole NES just as he had as a child.

Now, like any respectable hacker, [daftmike] didn’t let gaps in his knowledge stop him. This project was a learning experience. He had to teach himself a lot about 3D design and modeling, using Linux, and programming. But, the end result was surely worth the work; the attention to detail shows in features like the USB placement, the power and reset buttons, and of course the game cartridges which work with the magic of NFC and still include the insert and toggle action of the original cartridge carriage.

If you have a 3D printer and Raspberry Pi available, you could build a similar NES emulator yourself. But if you don’t have a 3D printer, but do have an original NES lying around, you could pull of the Raspberry Pi in a NES case hack. Whichever you do, the NES’s beauty deserves to be displayed in your home.

GameGirl: A Better Portable Raspberry Pi

April 17, 2016 by 8 Comments

For better or worse, the most popular use for the Raspberry Pi – by far – is media centers and retro game consoles. No, the great unwashed masses aren’t developing Linux drivers for their Pi peripherals, and very few people are tackling bare metal ARM programming. That doesn’t mean creating a handheld console based on the Pi isn’t a worthy pursuit.

For their entry for the 2016 Hackaday Prize, [David] and [Jean-André] are building a portable Pi console that’s much better than an old Bondo-encrusted Game Boy enclosure stuffed with hot glue and wires. They’re doing this project the right way with a hardware accelerated display, custom software, and a high quality case.

[David] is in charge of the hardware, and that means making a very, very small handheld console. The design of this GameGirl is extremely similar to the old-school Game Boy Pocket (or Game Boy Light). There’s a D-pad, four buttons, select, start, and two ‘shoulder’ buttons on the back. The build is based on the Raspberry Pi Zero, and thanks to the Pi’s standard 40-pin header, [David] is able to configure the display to use an RGB565 DPI interface. This means the display is stupidly cheap while still leaving a few GPIO pins left over for the SPI, buttons, backlight, and PWM audio.

[Jean-André] is the other half of the team, and his contributions to open source software make him exceptionally qualified for this project. He’s the main developer for Lakka, a DIY retro emulation console, and the #5 RetroArch contributor. No, this project isn’t using RetroPie – and there’s a reason for that. Emulator hackers are spending a lot of time optimizing emulators for the Raspberry Pi, only because of RetroPi. If these emulator hackers spent their time optimizing for an API like LibRetro, you could eventually play a working version of Pilotwings 64 on the Raspberry Pi and every other platform LibRetro is available for. All the effort that goes into making a game work with a Raspberry Pi is effort that goes into making that game work for the PSP, Wii, iOS, and a PC. Yes, its philosophical pissing in the wind while saying, ‘this is what the community should do’; this is open source software, after all.

With the right ideas going into the hardware and software, [David] and [Jean-André] have an amazing project on their hands. It’s one of the most popular entries and are near the top of the charts in the community voting bootstrap effort where every like on a project gets the team a dollar for their project. GameGirl is shaping up to be a great project, and we can’t wait to see the it in action.

Pip Boys As A Service

November 24, 2015 by 24 Comments

A few weeks ago Fallout 4 was released, and like all future games of the year, productivity has fallen through the floor, cosplayers are busy crafting outfits, and modders are busy tearing the game to pieces. As with all big game releases, Fallout 4 has a super-deluxe, ultra-collectible edition, and this version comes with its own Pip Boy, the in-game wrist-mounted user interface that manages stats, inventory, and quests.

This Pip Boy is actually functional, relying on a smartphone to mirror the display in-game Pip Boy. This, of course, means there must be some sort of communication between the game and a phone. [Kyle] found this somewhat interesting and decided to dig into these communications to see what else could be done with the real life mirror of the in-game Pip Boy

With a simple swipe of nmap, [Kyle] discovered two ports open on his PS4. By creating a relay to listen in on whatever is passing through these ports, [Kyle] built a tool that allows anyone to dump data from the in-game Pip Boy to any other service.

The library and command line tool work with PS4 and PC and are able to dump stats and data from the in-game Pip Boy to the outside world. It will be interesting to see what kind of mashups could be created with this; especially interesting would be a leaderboard for an entire office of vault dwellers, but a TV-sized Pip Boy would also suffice.

Yes, that is a challenge.

The Most Drool-Worthy Pip-Boy To Date Can Be Yours

November 16, 2015 by 33 Comments

Pip-Boy props are nothing new in the maker world, especially since the availability and prices of 3D printers have made the undertaking more straightforward. Something about bringing a piece of the Fallout universe into the real world is just incredibly appealing – so much so that Fallout 4 collector’s editions included a Pip-Boy phone case. However, because of practical limitations these props are usually just plastic shells that house a cell phone. [zapwizard] wasn’t satisfied with a purely aesthetic prop, so he has decided to design his own Pip-Boy 3000 Mk4 from scratch, while retaining as much of the functionality as possible.

For the few of you who are unfamiliar, the Pip-Boy is a wrist-mounted computer from the Fallout series of games. From a gameplay standpoint, it’s used to manage your character’s inventory, stats, quest data, and so on. Because of how often you interact with the Pip-Boy throughout the game, it has become very near and dear to the hearts of Fallout fans, which has driven it’s popularity for prop-making.

It’s no wonder, then, that we’ve featured a number of builds here on Hackaday in the past. All of these builds have been impressive, but [zapwizard] is taking it to a whole other level. As a product engineer, he certainly has the experience necessary to bring this to life, and he’s not skipping any details. He’s starting by modeling everything up in CAD, using Solid Edge. Every knob, button, dial, and latch has been reproduced in meticulous detail, and will be functional with completely custom electronics. [zipwizard] is still in the design phase, but he should be close to getting started on the actual build. He’s also considering offering a limited run of units for sale, so be sure to get in touch with him if that tickles your fancy!

Introducing The Nintendo Guitar Boy

September 18, 2015 by 10 Comments

Need to thrash out some wicked 8-bit riffs? There’s only one guitar you should be doing that with, and it’s a Guitar Boy!

[Fibbef], an administrator on BitFixGaming boards built this as an exhibition piece for his 2015 Game Boy Classic build off. He started the build just three months ago and we have to say we’re impressed. It’s a fully functioning Raspberry Pi Game Boy emulator — and a full fledged electric guitar. The A and B buttons double as volume and tone dials for the guitar, while also being push buttons for the Game Boy!

Under the hood is a Raspberry Pi B+ running RetroPie v2.3, with a 5″ LCD display, custom wooden buttons, the entire body is hand made, and a plexiglass shell covers the whole thing.
