The GBA Console You Never Knew You Wanted

June 13, 2025 by Tyler August 9 Comments

Do you like Nintendo games? How about handhelds? Do you prefer the now-venerable Game Boy Advance (GBA) to more modern platforms, but wish your aging eyes could enjoy its content on a large CRT instead of a dinky LCD? If you answered yes to all those questions, you are exactly the type of person [GouldFish on Games] made this custom console for, and you should probably be friends.

The external appearance of this hack is slick: a 3D printed console with the contours of the GBA in that iconic purple, but with a cartridge bay door like an NES and a SNES controller port. It’s the GBA console Nintendo never made, sitting next to a period-appropriate CRT. Playing GBA game on a CRT with an SNES controller is already hacky; what makes it really hacky is the guts are yet another Nintendo system — the DS Lite.

Why a DS Lite? Two reasons: one, it is cheaper to get a busted DS Lite than an old GBA mainboard. Two, as we covered before, the DS Lite can do composite-out with a relatively cheap add-on board. [GouldFish] really is hacking on the shoulders of giants, and they acknowledge it in the video. Aside from the composite-out board, he also makes use of community knowledge on how to make the DS Lite boot without screens or batteries.

Should you be interested in putting your own version of this console together, [GouldFish] was kind enough to share the STLs for the 3D printed enclosure, as well as the Gerber files for the custom PCB that interfaces with the SNES controller port.

We featured a CRT mod for an original Game Boy before, but this seems a lot more practical, if a lot less portable. [GouldFish] has no shortage of old titles and newer homebrew to chose from for this console, but they could always use more. We once featured a primer on how to get into the GBA homebrew scene, if you want to make a game.

This Retro Game Console Puts Vacuum Fluorescent Display To Good Use

March 7, 2023 by Dan Maloney 4 Comments

Small in size, low-resolution, blocky segments, and a limited color palette — all characteristics of the typical vacuum fluorescent display, any of which would seem to disqualify them as the display of choice for a lot of applications. But this is Hackaday, and we don’t really pay much attention to what we’re supposed to do, but rather to what’s fun and cool to do. So when we see something like a VFD game console, we just have to sit up and take notice.

In a lot of ways, the design of [Simon Boak]’s Arduino-based VFD console is driven by his choice of display. The Noritake Itron GU20X8-301 VFD is a “tricolor” display with eight rows of 20 rectangular pixels. Each pixel is composed of six short linear segments, with alternating red and blue colors. Turning on either set of segments yields one of the two base colors, while turning on both yields a sorta-kinda whitish color, if you squint a bit.

[Simon] chose a two-piece design for his console, with a separate controller and display. The controller holds the Arduino Nano and all the controls, plus a piezo buzzer for fun. The display case connects to the controller with a ribbon cable and holds the VFD power supply and driver. To celebrate the retro look of the VFD, both cases are decked out with woodgrain side panels. [Simon] chose appropriately blocky games for the console, like Snake, Conway’s Game of Life, and the venerable snow demo. We’d imagine Pong would be a good choice too, as well as perhaps Tetris if the display were flipped on its side.

We really like the look of this console, and we appreciate putting an otherwise obsolete display to use in a creative way. If you want to learn a little more about these displays, check out this love letter to the VFD.

DIY GameTank Game Console Gets Upgraded Cartridge

January 5, 2023 by Tom Nardi 2 Comments

Over the summer, you might recall seeing a homebrew 6502 game console called the GameTank grace these pages. The product of [Clyde Shaffer], the system was impressively complete, very well documented, and even had a budding library of games.

Recently, [Clyde] took to the r/electronics subreddit to show off the latest improvement to the GameTank: a revised removable cartridge. The biggest change this time around is the addition of 32 KB of battery-backed SRAM that gives games (or any other software that might be on the cartridge) some persistent storage to work with.

The GameTank Is The Latest And Greatest 8-bit Game Console

August 2, 2022 by Robin Kearey 15 Comments

The NES, Atari 2600, the Apple II, the Commodore 64 and the TurboGrafx-16 are just some of the many game consoles and home computers built around the 6502 CPU. And while the 6502 has been pretty much obsolete since the mid-’90s, that hasn’t stopped hackers from building new systems with it in the 21st century. Today we can even show you an entirely new 6502-based game console: the GameTank, designed and built by [Clyde Shaffer].

The GameTank was designed to be easy to build by anyone, and is therefore largely constructed from DIP chips that can be bought new at any component distributor. The main CPU is a WD65C02 running at 3.5 MHz, assisted by a 6522 I/O controller and 32 kB of RAM. Composite video is generated by a clever circuit made out of discrete logic chips. The video card comes with DMA for fast transfers and even includes a blitter, which enables it to move images around the screen quickly without loading the CPU.

For the controllers, [Clyde] decided to go for the more-or-less industry standard DE-9 connector gamepads as used on the Sega Genesis and various Atari consoles. He also made his own controller, a 3D printed one with four directional buttons, three action buttons and a start button. The buttons are implemented with Cherry MX Clear switches — an unusual choice for a gamepad perhaps, but they’re apparently very comfortable for long gaming sessions.

The console itself is also housed in a printed enclosure with a design reminiscent of the Nintendo 64. Game cartridges are inserted at the top and contain an EEPROM chip that can be written with a special programmer. The cartridge port also brings out several internal signals and can therefore be used as an expansion port, similar to the way Super NES cartridges could accommodate enhancement chips.

Games currently available include Tetris, the office-themed platformer Cubicle Knight, a Zelda-style adventure named Accursed Fiend, and a remake of the classic viral animation Bad Apple. [Clyde] provides a comprehensive stack of tools and example code and invites anyone interested to help develop more software for the platform. There’s also a hardware-accurate emulator, which is not only useful if you’re writing new code for the system but also if you simply want to try out the existing games in your browser.

Rolling your own 6502 system is great fun, and we’ve seen several examples over the years: some are built with huge bundles of wire, some are come with a clever programming language, some are so tiny they fit on your wrist, and some are simply beautifully made.

Giving A Console Controller Mouse-Like Precision Aim

September 4, 2021 by Danie Conradie 23 Comments

Controller vs keyboard and mouse is one of the never-ending battles in the world of gaming, with diehard proponents on both sides of the fence. [Tech Yesterday] has been working to create a controller that’s the best of both worlds. His latest Mouse Pro Controller V5 features an inverted mouse riding on ball bearings.

Mouse Pro Controller V1-3‘s main focus was to create the largest possible moving surface for an optical thumb mouse for precision aiming. However, [Tech Yesterday] found that one’s thumb doesn’t work well for traversing a large flat surface, but works better with a concave surface. On V4 he flipped the optical sensor around, embedding it in the controller, with a small circular “mouse pad” attached to his thumb. The concave surface was made from the diffuser of a large LED light bulb. It had slightly too much friction for [Tech Yesterday]’s liking, so he embedded an array of small ball bearings in the surface using magnets.

While this “thumb mouse” has excellent precision, it can be a bit slow when you need to make large movements, like when performing 360° no scopes for the clips. For these situations, [Tech Yesterday] embedded a thumb stick on the back of the controller to allow for fast sideways movements using his middle fingers.

[Tech Yesterday] is already working on V6, but feels close to the limit of his skills. If you are interested in working with him, be sure to get in touch! Modding controllers for fun and performance are great, but for gamers with prosthetic fingers it’s a requirement.

Consoles, Consoles On The Wall, Can Alexa Help Me Play Them All?

August 27, 2021 by Tom Nardi 2 Comments

If you’ve got a collection of classic game consoles, finding the space to set them all up can be a challenge. But the bigger problem is figuring out how to hook them all up to a TV that, at best, might only have two or three inputs. [odelot] recently wrote in to tell us how he solved both problems with his voice-controlled wall of gaming history.

To mount the systems to the wall, [odelot] designed and printed angled brackets that attach to specially shaped pieces of 3 mm MDF. They do a pretty good job of holding the systems at a visually interesting angle while making themselves scarce, with only the notoriously slick-bottomed Wii needing some extra clips on the front to keep it from sliding off. He also printed up a series of blocks and pipes, no doubt a reference to Mario Bros., to hold the power and video cables for each system.

As to connecting them all up to his TV, [odelot] picked up an eight-device Extron VGA switch that features a serial port for remote control. After getting all the systems adapted over to the appropriate video standard, he then wired an ESP8266 to the switch and wrote some code that ties it into Amazon’s Alexa voice assistant.

By just saying the name of the system he wants to play, the microcontroller will flick the switch over to the appropriate input and turn on a ring of blue LEDs under the appropriate shelf to signify which console has been selected. There’s even an array of solid state relays that will eventually control the mains power going to each system, though [odelot] hasn’t fully implemented it yet. Currently the electronics for this project live on a fairly packed breadboard, but it looks like he’s in the early stages of designing a proper PCB to clean it all up.

Not content to simply control a commercial A/V switch? In the past we’ve seen truly dedicated console collectors design their own custom switches from the ground up, complete with a display to show the currently selected system’s logo.

Giant Nintendo Switch Is Actually Playable

April 5, 2021 by Zach Zeman 6 Comments

The Nintendo Switch has been a hugely successful console for the century-old former playing card manufacturer. At least part of that success has come from its portability, of which [Michael Pick] has probably lost a bit with his 65-pound giant Nintendo Switch built for St. Jude’s Children’s Hospital. (Video, embedded below.) What he’s lost in portability has been more than made up in coolness-factor, though, and we’re sure the kids will appreciate that they can still play the monster gaming machine.

From its plywood body to the 3D-printed buttons, the supersized build looks solid. Docked inside the left Joy-Con is the actual console powering its big brother. Perhaps the biggest surprise, however, is that tiny (well, normal-sized) Joy-Cons are also hidden inside. These are manipulated via servos for the buttons and a direct pass-through setup for the joysticks to control games on the Switch.

While the Joy-Cons are unmodified and completely removable, [Michael] does recognize this isn’t necessarily the ideal solution. But he was certain it was a hack he could make work in the time he had, so he went for it. He’s looked into the controller emulation possible with Teensys and would probably use that solution for any giant Switch projects in the future. Of course, with this build, players can still pair regular Joy-Cons and pro controllers for more practical gaming.

Most Nintendo mods we see attempt to make the console smaller, not larger, so this is an eye-catching change of pace. Unfortunately, we don’t get to see the colossal console in action after it was installed, only some stills of hospital staff wheeling it in the front doors. But we can imagine that the children’s smiles are at least as big as ours were when we saw it.
