Three-Monitor Ridge Racer Machine Emulated In MAME

April 18, 2026 by Zoe Skyforest 11 Comments

When Ridge Racer hit the arcades in the early 1990s, it came in a few different versions. The last variant used three large CRTs to create a wraparound display for the player. Incredibly rare, it’s believed that only a single-digit number of machines remain in existence. [beaumotplage] has secured a remaining example, and been working to preserve this historical artifact.

The first mission when it comes to this machine was to dump the ROMs, which have thus far not been preserved in any major archive. With that done, [beaumotplage] worked to hack a version of MAME that could emulate the Three Monitor Version’s unique mode of operation. As it turns out, each screen is driven by its own arcade board, with the three boards linked via C139 serial links. To emulate this, the trick was simply to write some C139 linkup code and run three versions of MAME all at once, letting them communicate with each other as the original boards would have. It’s a little janky in operation right now, but it does work!

You can download the hacked version of MAME for three-monitor operation here, though note that this does not include the ROM dumps from the machine itself. We look forward to seeing if the hardware ends up getting a full restoration back to operational standard, too.

Overall, this work goes to show that arcade preservation and archival work sometimes requires getting deep into the nitty-gritty technical stuff.

The Decisioninator Decides Dinner, Saves Marriage

September 5, 2025 by Tyler August 14 Comments

For something non-explosive, this might be the most American project we’ve featured in a while. [Makerinator]’s domestic bliss was apparently threatened by the question “what shall we have for dinner”– that’s probably pretty universal. Deciding that the solution was automation is probably universal to software devs and associated personalities the world over. That the project, aptly called “The Decisioninator” apes a popular game-show mechanic to randomly select a fast-food restaurant? Only people with 100-octanes of freedom running through their veins can truly appreciate its genius.

In form factor, it’s a tiny slot machine which [Makerinator] fabbed up on his laser cutter. The lovely “paintjob” was actually a print out with dye-sublimation ink that was transferred to plywood before laser cutting. Mounted to this are illuminated arcade buttons and a small ISP display. The interface is simplicity itself: the big button spins a virtual “wheel” on the display (with sound effects inspired by The Price is Right) to tell the family what deliciously unhealthy slop they’ll be consuming, while the other button changes decision modes. Of course you can pick more than just dinner with The Decisioninator. You need only decide what spinners to program. Which, uh, that might be a problem.

Luckily [Makerinator] was able to come up with a few modes without recursively creating a The Decisioninator-inator. He’s got the whole thing running on a Pi4, which, with its 1980s supercomputer performance, is hilariously overpowered for the role it plays (in true American fashion). He’s coded the whole thing in the Flame Engine, which is a game engine built on the Flutter UI toolkit by American technology giant Google.

What’s more American than tech giants and fast food? A propane powered plasma cannon, for one thing; or maybe mental gymnastics to translate into freedom units, for another.

Thanks to [Makerinator] for the tip.

A Second Rare Atari Cabinet 3D Printed

January 23, 2025 by Jenny List 5 Comments

Last year we covered the creation of a 3D-printed full-size replica of an original Computer Space arcade machine, the legendary first glimmer from what would become Atari, one of the most famous names in gaming. The flowing exuberance of glitter-finished fibreglass made these machines instantly recognisable. Not so well known though is that there was a second cabinet in a similar vein from Atari. Space Race is most often seen in a conventional wooden cabinet, but there were a limited number of early examples made in an asymetric angular take on the same fibreglass recipe as Computer Space. They’re super rare, but that hasn’t stopped a replica being made by the same team and documented in a pair of videos by [RMC – The Cave].

Just like the earlier project, a start was made with a 3D model. In this case an owner of a real cabinet was found, who ran off a not-very-good scan with a mobile phone. This was then used as the basis for a much better model, and the various pieces were printed. Using all manner of reel ends gave the assembled cabinet a coat of many colours look, but after a coat of filler, paint, and then glitter lacquer, you would never know. Electronics come courtesy of modern emulation hardware and a Sony CCTV monitor, and the joysticks were made from a mixture of common hardware and 3D prints. Both the videos are below the break, and you’ll now no doubt also want to see the original project..

Building The Unreleased Lemmings Arcade Cabinet From 1991

July 29, 2024 by Maya Posch 7 Comments

Back in the early 90s the world was almost graced with an arcade version of Lemmings, but after a few board revisions it was abandoned in 1991. Now the folk over at UK-based [RMC – The Cave] on YouTube have managed to not only get their mitts on a nearly finished prototype board, but have also designed and built a period-appropriate cabinet to go with it. This involved looking at a range of arcade cabinets created by Data East and picking a design that would allow both for the two-player mode of the game, and fit the overall style.

Arcade cabinets came in a wide range of cabinet styles and control layouts, largely defined by the game’s requirements, but sometimes with flourishes to distinguish the cabinet from the hundred others in the same arcade.

In this particular case the typical zig-zag (Z-back) style was found to be a good fit as on the Data East Night Slashers 1993-era cabinet, which then mostly left the controls (with two trackballs) and cabinet art to figure out. Fortunately there is plenty of inspiration when it comes to Lemmings art, leading to the finished cabinet with the original mainboard, the JAMMA wiring harness with MultiPi JAMMA controller, a 19″ CRT monitor and other components including the 3D printed controls panel.

With more and more new arcades popping up in the US and elsewhere, perhaps we’ll see these Lemmings arcade cabinets appear there too, especially since the ROMs on the prototype board were dumped for convenient MAME-ing.

Gather ‘Round This Unique 4-Player Arcade Cabinet

May 11, 2024 by Tom Nardi 4 Comments

Usually when we see arcade cabinet builds, they’re your standard single-player stand up variety. Even one of them takes up quite a bit of room, so as appealing as it might be to link up two or more cabinets together for the occasional multiplayer session, the space required makes it a non-starter for most of us.

But this cleverly designed 4-player cocktail cabinet from [OgrishGadgeteer] goes a long way towards solving that problem. The circular design of the cabinet gives each player a clear view of their respective display in a much smaller footprint than would otherwise be possible, and the glass top allows the whole thing to double as an actual cocktail table when it’s not game time.

The cabinet was modelled in 3D before construction.

According to a post on r/cade, it took [OgrishGadgeteer] three months to go from paper sketches of the cabinet’s basic shape to the final product. Most of the components were picked up on the second hand market, which brought the total cost of the build to around $350. That wouldn’t have been a surprising price for a traditional full-size cabinet build, so for this, it seems like an absolute steal.

A Dell OptiPlex 7060 small form factor PC provides the power for this build, with the video output passing through a 4-way VGA distribution amplifier into 20 inch monitors. At $75, the four player control kit ended up being the single most expensive component of the build, though you could make do with some parts bin buttons and a Pi Pico if you wanted to really bring this one in on a budget.

Perhaps the most surprising element of the whole build is that, despite the cabinet’s complex design, [OgrishGadgeteer] pulled it off without a CNC to cut the plywood panels. Instead, a vinyl cutter was used to make full-size templates of the cuts and holes that needed to be made, which were attached directly to the wood. After that, it was just a matter of following the lines with a jigsaw. Not the fastest or most convenient solution, but it’s hard to argue with the final results.

We’ve seen other cocktail cabinet builds in the past, but this is the first that managed to cram four players in. Well, unless you count Dungeons & Dragons, anyway.

3D Printing Computer Space

March 31, 2024 by Jenny List 6 Comments

The first computer game available as a commercial arcade cabinet is unsurprisingly, a rare sight here in 2024. Nolan Bushnel and Ted Dabney’s 1971 Computer Space was a flowing fiberglass cabinet containing a version of the minicomputer game Spacewar! running on dedicated game hardware. The pair would of course go on to found the wildly successful Atari, leaving their first outing with its meager 1500 units almost a footnote in their history.

Unsurprisingly with so relatively few produced, few made it out of the United States, so in the UK there are none to be found. [Arcade Archive] report on a fresh build of a Computer Space cabinet, this time not in fiberglass but via 3D printed plastic.

The build itself is the work of [Richard Horne], and in the video he takes us through the design process before printing the parts and then sticking them all together to make the cabinet. Without a real machine to scan or measure he’s working from photographs of real machines, working out dimensions by reference to other cabinets such as PONG that appear alongside them. The result is about as faithful a model of the cabinet as could be made, and it’s cut into the many pieces required for 3D printing before careful assembly.

This is the first in a series, so keep following them to see a complete and working Computer Space take shape.

Defender Arcade Rebuilt To Settle A Childhood Memory

March 3, 2023 by Arya Voronova 7 Comments

[Jason Winfield] had a nemesis: the Defender arcade machine. Having put quite a number of coins into one during his childhood, he’s since found himself as a seasoned maker, and decided to hold a rematch on his own terms. For this, he’s recreated the machine from scratch, building it around the guts of a Dell laptop, and he tells us the story what it took to build a new Defender in this day and age.

Defender was a peculiar machine — it was in cocktail table format, unlike many other arcade machines of that period. From pictures, he’s redesigned the whole thing in Fusion 360, in a way more desk-friendly format, but just as fancy looking as before.

As for the laptop, gutting it for its mainboard, screen, and speakers was a surprisingly painless procedure — everything booted up first try. A few board-fitted brackets and a swap from a HDD to a USB flashdrive for the OS later, the electronics were ready. As he was redesigning the entire arcade machine anyway, the new design control panel was also trimmed down for ease of use, while preserving the original colorful look.

All in all, an impressive build from [Jason]. After all was set and done, we don’t doubt that he went on to, let’s say, settle some old scores. It’s not the first time we see a desktop-sized arcade cabinet, and you gotta admire the skills making such a machine smaller while sticking to the old-timey aesthetic! Or, perhaps, would you like a cabinet that’s more subtle?
