You’ve probably seen a few of these miniature arcade games online or in big box retailers: for $20 USD or so you get scaled-down version of a classic arcade cabinet, perfect for a desk toy or to throw up on a shelf as part of your gaming collection. Like any good Hackaday reader, you were probably curious about what makes them tick. Thanks to [wrongbaud], we don’t have to wonder anymore.
Over the course of several blog posts, [wrongbaud] walks readers through the hardware and software used in a few of these miniature games. For example, the Rampage cabinet is using a so-called “NES on a Chip” along with a SPI flash chip to hold the ROM, while Mortal Kombat is using a Genesis emulation solution and parallel flash. It wouldn’t be interesting if they didn’t throw you a few curves now and again, right?
But these are more than simple teardowns. Once [wrongbaud] gives an overview of the hardware, the next step is reading the respective flash storage and trying to make sense of the dumped data. These sort of games generally reuse the hardware among a number of titles, so by isolating where the game ROM is and replacing it, they can be made to play other games without hardware modification. Here, this capability is demonstrated by replacing the ROM data for Rampage with Yoshi’s Cookie. Naturally it’s one of those things that’s easier said than done, but it’s an interesting proof of concept.
The Mortal Kombat cabinet is a newer addition to the collection, so [wrongbaud] hasn’t progressed quite as far with that one. The parallel flash chip has been dumped with the help of an ESP32 and a MCP23017 I/O expander, and some Genesis ROM headers are identifiable in the data, but there’s still some sifting to be done before the firmware structure can be fully understood.
Even if you’re not in the market for a diminutive arcade experience, the information that [wrongbaud] has collected here is really phenomenal. From understanding protocols such as I2C and SPI to navigating firmware dumps with a hex editor, these posts are an invaluable resource for anyone looking to get started with reverse engineering.
In this day and age of cheap and easy emulation, it’s more tempting than ever to undertake a home arcade cabinet build. If you want to show off, it’s got to have a light show to really pull the crowds in. To make that easier, [Patricio] put together a software package by the name of LEDSpicer.
The project came about when [Patricio] was working on his Linux-based MAME cabinet, and realised there were limited software options to control his Ultimarc LED board. As the existing solutions lacked features, it was time to get coding.
LEDSpicer runs on Linux only, and requires compilation, but that’s not a huge hurdle for the average MAME fanatic. It comes with a wide variety of animations, as well as tools for creating attract modes and managing LEDs during gameplay. There are even audio-reactive modes available for your gaming pleasure. It’s open source too, so it’s easy to tinker with if there’s something you’d like to add yourself.
It’s a great package that should help many arcade builders out there. LEDs can be used to great effect on a cabinet build; this marquee is a particularly good example. Video after the break.

Upon announcement of the Arcade1up replica arcade cabinets earlier this year, many laid in waiting for the day they could see a teardown. A four foot tall cab with an LCD outputting the proper 4:3 aspect ratio and the simple construction of IKEA furniture certainly seemed appealing. In theory, it wouldn’t take long to customize such a piece of hardware provided the internals lent themselves to that sort of thing. Now that the cabinets are on store shelves, [ETA Prime] made a tutorial video on his method for upgrading the Arcade1up cabinet with a Raspberry Pi calling the shots.
The entirety of the mod is solder-free and uses plenty of readily available parts from your favorite online reseller. The brains of the operation is a Raspberry Pi 3 Model B+ running Emulation Station. The Arcade1up Street Fighter 2 cabinet’s less than stellar audio receives an upgrade in a 2x20W car audio amp, while the middling joysticks are swapped out for some more robust Sanwa-clone ball tops.
Since there is no “select/coin” button natively, [ETA Prime] added some and in the process replaced them all with beefier LED-lit 30mm buttons. The replacement joysticks and buttons were all part of a kit, so they plug-in conveniently to a plug and play USB encoder. To adapt the 17″ LCD’s output over LVDS, [ETA Prime] elected to go with an LCD controller board that outputs DVI, VGA, or HDMI. Luckily the Arcade1up cabinet’s 12V power supply could be reused to power the LCD controller board and in the process bring down the overall cost of the upgrade.
While this Arcade1up cabinet mod won’t solve the whole “bats versus ball tops” argument, it does provide a template to build on. The tutorial video is below and the list of parts used can be found in the YouTube description.

An arcade cabinet is one of those things that every gamer wants at home, but few ever get. Getting a real arcade cabinet is usually expensive, and building one yourself is no small feat. There are kits you can get now which help the process along, generally taking the form of pre-cut cabinet parts, but with them comes the quiet shame of kit-building. What if your friends found out you used a kit instead of designing it yourself? The drama is almost too much to think about.
That’s how [Bogdan Berg] felt about it, at least. Not content with just getting a pre-cut cabinet kit from eBay, he decided to design and build his own bartop arcade machine in just one week: fast enough for him to fit the whole thing into his Christmas vacation. We don’t know what Christmas was like for his friends and family this year with him toiling away on this beautiful build the whole time, but we can confidently say his Christmas was awesome.
He designed the cabinet in Fusion 360, working around the limitation that the laser cutter he had access to had a work area of 24 inches by 18 inches. Some interesting design choices were made here, including going with a tab and slot construction method. While [Bogdan] admits that this aesthetic isn’t always popular, he liked how sturdy it makes the final product.
He was originally going to use plywood for the cabinet, but owing to the fact that he couldn’t find any pieces that weren’t warped locally, he switched over to MDF. Using MDF did mean he had to seal all the cut pieces with shellac before painting, but in the end he’s happy with the final lacquer paint job; even if it did take more work and materials than he anticipated.
The hardware is pretty much the standard for DIY arcades these days: a 17 inch LCD monitor he had laying around is used for the display, a two player joystick and button kit from Amazon provides the user interface, and emulation is provided by a Raspberry Pi 3 running RetroPie. A recessed door in the rear allows him to get into the machine will still maintaining a finished look on the backside.
While the size of them may vary wildly, DIY arcade cabinets are always a popular project. Whether shamelessly emblazoned with our logo or playing host to glorious LED lighting, it seems like the design of these cabinets provide as much entertainment as the games they play.

Most of us would probably like to have an arcade cabinet at home, but it’s hard to justify the space they take up. Sure it’s an awesome conversation starter when friends are over, and you might even play it regularly, but at some point you’ll look over at the corner and realize there’s probably something more practical you could be doing with that particular section of the room.
Perhaps the solution is to just make a smaller one. You could do one at half scale, or even desktop sized. But why stop there? Why not make one so small that you could put the thing in a drawer when you don’t need it? While it might be more of an academic experiment than a practical entertainment device, [RedPixel] has managed to create just such an easily concealable arcade cabinet out of a Pi Zero and laser cut wood. At only 83 mm high, this may well be the smallest functional arcade cabinet ever made (at least for now).
All of the cabinet parts were drawn in Inkscape and cut out of 3 mm plywood. The buttons and joystick are wired directly to the Pi Zero’s GPIO pins and configured with Adafruit-retrogame. The display is a SPI ILI9163, which [RedPixel] previously documented on his site.
The Pi is running the ever-popular RetroPie, which allows this tiny arcade cabinet to emulate 1000’s of console and arcade games, assuming you can deal with the controls anyway. While [RedPixel] has uploaded a video of his lilliputian cabinet running an emulator, there’s no video of him actually playing the thing. While we don’t doubt that it functions as advertised, gameplay on such a tiny array of inputs must be very difficult.
This may be the smallest functional arcade cabinet to date, but it isn’t without challengers. We’ve covered a number of very impressive builds that manage to invoke the look and feel of a hulking coin-up despite fitting neatly on your desk.

Like many of us, [Alex] spent a large part of his childhood feeding coin after coin into one arcade game or another. Galaga is one of his all-time favorites, and he has wanted to build a Galaga cabinet for a long time. Once his workshop was ready for the job, it was time to cross it off the list.
The cabinet is built to 4/5 scale. This is a great size because he gets the stability and feel of a full-size machine, but it’s much easier to move it around. As you might expect, there’s Pi in the cabinet. The display is an old TV that [Alex] found in a Dumpster. And although it works great, it would go into standby instead of powering off along with everything else. To get around this, [Alex] built an automatic remote control with an IR LED and an Arduino Diecimila. After a five-second wait, it sends the power-on code to the TV and switches the input. The TV is supposed to be in portrait mode for Galaga, but this proved to be a challenge. Changing the orientation at the Pi level resulted in poor performance and choppy sound, so he changed it at the game execution level.
We are continually impressed by the diversity of [Alex]’s builds and the care that goes into them. Who could forget his beautiful sidewalk graffiti machine or the time he showed us how to photograph stuff that’s not there? Make the jump to see a brief demonstration followed by a two-part build video.

Everyone’s got an unused or even quasi-broken tablet lying around these days. [sairuk] has three kids, and somehow ended up with three broken tablets in short order. We’re not saying that correlation implies causality…
The digitizers were shattered, and since they were relatively cheap tablets to begin with, [sairuk] started thinking what could be done with a tablet that doesn’t have touch sensing anymore. He tried making an e-book reader for his kids, but somehow the idea of a MAME “cablet” (get it?) won out in the end. We’re not surprised: simple woodworking, gaming, and electronic hacking. What’s not to love?
This writeup goes into a lot more detail, so check that out too. He and his sons built up cardboard prototypes first (we love cardboard!) and then transferred their plans over to wood for the final “rough cut”. A PS1 controller reads out the joystick and buttons, and a PS1 -> USB adapter plus a USB-OTG cable connects that to the tablet. They also removed the batteries and built in a permanent power supply. Everything is simple and cheap, but the results are still impressive. Although they claim their build isn’t finished to the utmost, it looks pretty darn good to us.
We’re all frackers, so it’s satisfying to see a “junk” tablet put to good use. We’re wondering what [sairuk] is going to do with his other two tablets — we’ve got a suggestion for what he should do if he had twenty kids.
