Dumping A N64 Development Cartridge Safely

November 2, 2020 by 8 Comments

Retro gaming enthusiasts have always had great interest in rarities outside the usual commercial titles. Whether they be early betas, review copies, or even near-complete versions of games that never made it to release, these finds can be inordinately valuable. [Modern Vintage Gamer] recently came across a pre-release version of Turok 3 for the Nintendo 64, and set about dumping and preserving the find. (Video, embedded below.)

With one-off cartridges like these, it’s important to take the utmost care in order to preserve the data onboard. Simply slapping it into a regular console might boot up the game, but carries with it a non-zero chance of damaging the cart. Instead, the first step taken was to dump the cart for archival purposes. When working with a prototype cart, commodity dumpers like the Retrode aren’t sufficient to do the job. [Modern Vintage Gamer] notes that a Doctor V64 or Gameshark with a parallel port could work, but elects to use a more modern solution in the form of the Ultrasave and 64drive.

With the cartridge backed up and duplicated onto the 64drive, the code can be run on a real console without risk of damage to the original. At first glance, the game appears similar to the final retail version. Analysis of the dump using a file comparison tool suggests that the only differences between the “80% Complete” ROM and the retail edition are headers, leading [Modern Vintage Gamer] to surmise that the game may have been rushed to release.

While in this case the dump didn’t net an amazing rare version of a retro game, [Modern Vintage Gamer] does a great job of explaining the how and why of the process of preserving a vintage cartridge. We look forward to the next rare drop that shakes up the retro world; we’ve seen efforts on Capcom arcade boards net great results. Video after the break.

An Epic Quest To Build The Perfect Retro Handheld

November 26, 2019 by 15 Comments

It’s a good time to be a fan of classic video games. Most of us carry around a smartphone that’s more than capable of emulating pretty much everything from the 32-bit era on down, and if you want something a little more official, the big players like Sony and Nintendo have started putting out “retro” versions of their consoles. But even still, [Mangy_Dog] wasn’t satisfied. To get the portable emulation system of his dreams, he realized he’d have to design and build it himself.

The resulting system, which he calls the “Playdog Blackbone”, is without a doubt one of the most impressive DIY builds we’ve ever seen. While there are still some issues that he’s planning on addressing in a later version of the hardware, it wouldn’t be an exaggeration to say that there’s commercially available game systems that didn’t have half as much thought put into them as the Blackbone.

Which is, incidentally, how this whole thing got started. The original plan was to buy one of those cheap emulation handhelds, which invariably seem to come in the form of a PSP clone, and fit it with a Raspberry Pi. But [Mangy_Dog] quickly realized that not only were they too small to get everything he wanted inside, but they also felt terrible in the hand. Since he wanted the final product to be comfortable to play, his first step was to design the case and get feedback on it from other retro game enthusiasts.

After a few iterations, he arrived at the design we see today. Once he printed the case out on his SLA printer, he could move on with fitting all of his electronics inside. This takes the form of a custom PCB “motherboard” which an Orange Pi Zero Plus2 (sorry Raspberry fans) connects to. There’s actually a surprising amount of room inside the case, enough for niceties like dual speakers and a fan complete with ducting to keep the board cool.

Unsurprisingly, [Mangy_Dog] says a lot of people have been asking him if they can buy their own version of the Blackbone, and have suggested he do a crowdfunding campaign to kick off mass production. While he’s looking at the possibility of resin or injection molding the case so he can produce a few more copies, on the whole, his attention has moved on to new projects. Which frankly, we can’t wait to see.

If you’re interested in slightly more modern games, we’ve seen a number of handhelds based on “trimmed” Nintendo Wii’s which you might be interested in. While they might not have the sleek external lines of the Blackbone, the work that goes into the electronics is nothing short of inspirational.

Badge builder's meetup at DC27

Pictorial Guide To The Unofficial Electronic Badges Of DEF CON 27

September 19, 2019 by 15 Comments

DEF CON has become the de facto showplace of the #Badgelife movement. It’s a pageant for clever tricks that transform traditional green rectangular circuit boards into something beautiful, unique, and often times hacky.

Today I’ve gathered up about three dozen badge designs seen at DC27. It’s a hint of what you’ll see in the hallways and meetups of the conference. From hot-glue light pipes and smartphone terminal debugging consoles to block printing effects and time of flight sensors, this is a great place to get inspiration if you’re thinking of trying your hand at unofficial badge design.

If you didn’t catch “The Badgies” you’ll want to go back and read that article too as it rounds up the designs I found to be the craziest and most interesting including the Car Hacking Village, Space Force, SecKC, DC503, and Frankenbadge. Do swing by the Hands-On articles for the AND!XOR badge and for [Joe Grand’s] official DC27 badge. There was also a lot of non-badge hardware on display during Hackaday’s Breakfast at DEF CON so check out that article as well.

Enough preamble, let’s get to the badges!

The Atomic Pi: Is It Worth It?

June 6, 2019 by 140 Comments

Several months ago, a strange Kickstarter project from ‘Team IoT’ appeared that seemed too good to be true. The Atomic Pi was billed as a high-power alternative to the Raspberry Pi, and the specs are amazing. For thirty five American buckaroos, you get a single board computer with an Intel processor. You get 16 Gigs of eMMC Flash, more than enough for a basic Linux system and even a cut-down version of Windows 10. You have WiFi, you have Bluetooth, you have a real time clock, something so many of the other single board computers forget. The best part? It’s only thirty five dollars.

Naturally, people lost their minds. There are many challengers to the Raspberry Pi, but nothing so far can beat the Pi on both price and performance. Could the Atomic Pi be the single board computer that finally brings the folks from Cambridge to their knees? Is this the computer that will revolutionize STEM education, get on a postage stamp, and sell tens of millions of units?

No. The answer is no. While I’m not allowed to call the Atomic Pi “literal garbage” because our editors insist on the technicality that it’s “surplus” because they were purchased before they hit the trash cans, there will be no community built around this thirty five dollar single board computer. This is a piece of electronic flotsam that will go down in history right next to the Ouya console. There will be no new Atomic Pis made, and I highly doubt there will ever be any software updates. Come throw your money away on silicon, fiberglass and metal detritus! Or maybe you have a use for this thing. Meet the Atomic Pi!

Thumbs Up For This CRT Handheld Gaming Console

May 6, 2019 by 10 Comments

Despite all the progress video game graphics have made, it is safe to say that we won’t see any decline in oldschool 8-bit games any time soon. For some it’s about nostalgia, for others it’s just a great and simple-enough first step into game development itself. For [gocivici] it was a bit of both when he built this camcorder style, one-button gaming console.

With a Raspberry Pi Zero running PICO-8 at its core, [gocivici] salvaged the viewfinder of an old camcorder for the display, and that way turned it into a whole other kind of handheld console. For full ergonomic handling, one single, thumb-operated push button serves as only control option. This of course makes it a bit challenging to re-use existing games that would require more input options, so he and some friends decided to just write a suitable game on their own with the hopes that others might follow.

Unfortunately we don’t see a lot of projects using these old camcorder viewfinders, and considering modern LCD and OLED options it’s not really that surprising, but there’s just something intriguing about these tiny CRTs. So in case you want to see more of them, have a look at this tiny Atari display, and the DIY night vision monocle from a few years back. And to keep your eyes safe and sound, [gocivici] got you covered as well.

Raspberry Pi Breathes Life Into A Scale Model SEGA

April 3, 2019 by 9 Comments

Miniature game consoles are all the rage right now. Many of the big names in gaming are releasing their own official “mini” versions of their classic machines, but naturally we see plenty of DIY builds around these parts as well. Generally they’re enclosed in a 3D printed model of whatever system they’re looking to emulate, but as you might expect that involves a lot of sanding and painting to achieve a professional look.

But for SEGA Genesis (or Mega Drive as it was known outside the US) fans, there’s a new option. A company by the name of Retro Electro Models has released a high-fidelity scale model of SEGA’s classic console, so naturally somebody hacked it to hold a Raspberry Pi. Wanting to do the scale detailing of the model justice, [Andrew Armstrong] went the extra mile to get the power button on the front of the console working, and even added support for swapping games via RFID tags.

[Andrew] uses the Raspberry Pi 3 A+ which ended up being the perfect size to fit inside the model. Fitting the Pi Zero would have been even easier, but it lacks the horsepower of its bigger siblings. The RFID reader is connected to the Pi over SPI, and the reed switch used to detect when the power switch has been moved is wired directly to the GPIO pins. The system is powered by a USB cable soldered directly to Pi’s PCB and ran out a small hole in the back of the case.

For input, [Andrew] is using a small wireless keyboard that includes a touch pad and gaming controls. Unfortunately, it has a proprietary receiver which had to be integrated into the system. In a particularly nice touch, he used snipped off component leads to “wire” the receiver’s PCB directly to the pins of the Pi’s USB port. Not only does it look cool, but provides a rigid enough connection that he didn’t even need to glue it down to keep it from rattling around inside the case. Definitely a tip to keep in the back of your mind.

The software side of this project is about what you’d expect for an emulation console, though with the added trickery of loading games based on their RFID tag. At this point [Andrew] only has a single “cartridge” for the system, so he simply drops the tags into the cartridge slot of the console to load up a new title. It doesn’t look like Retro Electro Models is selling loose cartridges (which makes sense, all things considered), so there might still be a job for your 3D printer yet if you want to have a library of scale cartridges to go with your console.

For those of you who were on Team Nintendo in the 1990’s, we’ve seen a similar build done with a 3D printed case. Of course, if even these consoles are a bit too recent for your tastes, you could build a miniature Vectrex instead.

2600-Inspired Handheld Brings The Faux Woodgrain

January 3, 2019 by 4 Comments

The Atari 2600 is a console from a very different time, when home appliances, furniture, and even automobiles were all covered in fake vinyl woodgrain veneer. Somehow it was the in thing for a decade, and then immediately became tacky overnight. Regardless, if you want to evoke the era, that’s what you do – and that’s exactly what [Christian] did with this handheld RetroPie build.

An early concept sketch shows off [Christian]’s art skills.
The technical side of things is fairly routine in these parts – a Pi Zero runs RetroPie so you can play emulated games from the mid-90s and earlier. It’s the visual presentation that we particularly enjoy. The look of the early Atari is evoked through clever use of materials. The body is in black plastic, with blocky red buttons for controls. It’s finished with a vinyl woodgrain applique around the screen, and we think it’s a wonderful aesthetic.

The files to print your own are available on Thingiverse, and [Christian] has provided a basic guide to sourcing similar parts. It’s all common stuff, readily available on eBay or elsewhere.

We love seeing retro throwbacks like this – the tiny Macintosh Plus from the 2017 Superconference is a particular highlight.
