Should you happen to have an HP7440A or similar plotter hanging around, you could have a quick game of Flappy Bird — or Plotty Bird as [WesleyAC] calls it. Just be sure you have some blank paper. The whole thing fits in about 200 lines of Rust code and — according to the author — gets to about 20 frames per second.
Watching the thing go, it appears that it draws a random set of pipes and then traces your flight path on the same page in real time.
The Arduboy, as you might have guessed from the name, was designed as a love letter to the Nintendo Game Boy that many a hacker spent their formative years squinting at. While the open source handheld is far smaller than the classic DMG-01, it retains the same general form factor, monochromatic display, and even the iconic red LED to the left of the screen. But one thing it didn’t inherit from the original was the concept of removable game cartridges. That is, until now.
Over the last year, [Mr.Blinky] and a group of dedicated Arduboy owners have been working on adding a removable cartridge to the diminutive handheld. On paper it seemed easy enough, just hang an external SPI flash chip off of the test pads that were already present on the Arduboy PCB, but to turn that idea into a practical cartridge required an immense amount of work and discussion. The thread on the Arduboy community forums covers everything from the ergonomics of the physical cartridge design to the development of a new bootloader that could handle loading multiple games.
The first problem the group had to address was how small the Arduboy is: there’s simply no room in the back to add in a cartridge slot. So a large amount of time is spent proposing different ways of actually getting the theoretical cartridge attached to the system. There was some talk of entirely redesigning the case so it could take the cartridge internally (like the real Game Boy), but this eventually lost out for a less invasive approach that simply replaced the rear of the Arduboy with a 3D printed plate that gave the modders enough room to add a male header along the top edge of the system.
As an added bonus, the cartridge connector doubles as an expansion port for the Arduboy. While perfecting the design, various forum users have chimed in with different gadgets that make use of the new port, from WS2812B LEDs to additional input devices like joysticks or a full QWERTY keyboard. Even if you aren’t interested in expanding the storage space on your Arduboy, being able to plug in new hardware modules certainly opens up some interesting possibilities.
In fact, the project so impressed Arduboy creator [Kevin Bates] that he chimed in on the topic last month to announce he would start looking into integrating the community’s cartridge modification into the production hardware. If all goes well, pretty soon there might be an official upgrade path for those who want to expand what this tiny nostalgia machine is capable of.

It takes a lot of work to build a modern video game. Typically an entire company will spend months (at least) developing the gameplay, selecting or programming an engine, and working out the bugs. This amount of effort isn’t strictly necessary for older video game systems though, and homebrew developers are quite often able to develop entire games singlehandedly for classic systems. In the past it would have taken some special software, programming knowledge, and possibly hardware, but now anyone can build games for the original Game Boy with minimal barriers of entry.
The project is known as GB Studio and allows people to develop homebrew games for the 8-bit handheld system without programming knowledge. Once built, the games can be played on any emulator or even loaded onto a cartridge and played on original hardware if a flash cart is available. Graphics can be created with anything that can create a .png image, and there are also some features that allow the game to be played over a web browser or on a mobile device.
While it seems like the gameplay is limited to RPG-style games, this is still an impressive feat, and highly useful for anyone curious about game development. It could also be an entry into more involved game programming if it makes the code of the games available to the user. It could even lead to things like emulating entire cartridges on the original hardware.

It was foolish to think that the adventure of the Mario Bros. would ever exist outside of the castle walls of the Nintendo Entertainment System. Except for that one time it did. The Hudson Soft company was a close collaborator with Nintendo, and parlayed that favor into being tasked with bringing Super Mario Bros. to platforms beyond the NES. The result of that collaboration would be 1986’s Super Mario Special, a port for the NEC PC-88 line of desktop computers. What ended up on that 5.25″ floppy sounded reminiscent of the Famicom original, but with a grand total of four colors (including black) and not a single scrolling screen in sight; Super Mario Special felt decidedly less than spectacular to play. Those eternally flickering sprites mixed with jarring blank screen transitions would never make it outside of Japan, so for a large swath of the world Mario would remain constrained to a gray plastic cartridge for years to come.
There are no shortage of ways to play Super Mario Bros. these days. Emulation in all of its various official and unofficial forms has taken care of that. Virtually everything with a processor more capable than the NES’s 6502 can play host to the Mushroom Kingdom, however, machines more contemporary with the NES still lacked access to the iconic title.
Enter the 2019 port of Super Mario Bros. for the Commodore 64 by [ZeroPaige]. A culmination of seven years work to port the game onto one of the most prolific computers of the eighties was a clear feat of brilliance and an amazing bit of programming that would have taken 1986 by storm. No pale imitation, this was Mario on the C64. Despite all of the nuance in recreating the jump-and-run model of the original paired with enveloping all eight sound channels of a dual SID chip setup, Nintendo saw fit to stifle the proliferation of this incredible 170 kB of software because they claim it infringes on their copyright.

We’ve seen more projects based on books, TV shows, movies, and video games than we could ever hope to count. Hackers and makers derive inspiration from what they see around them, and it turns out there’s considerable overlap between the folks who sit in their labs building stuff all day and the ones who spend their free time playing games or watching movies. Big surprise, right? But among them, few can match the influence of the Fallout franchise.
As the latest entry in a long line of incredible Fallout-inspired builds, we present the Octoglow VFD by [Michał Słomkowski]. While this build isn’t trying to replicate anything directly from the games, it captures all the hallmarks that make up the game’s distinctive post-apocalyptic chic : antiquated vintage components, exposed internals, and above all, a dirty, industrial look. It’s supposed to look like somebody built the stuff out of parts they found in the trash, primarily because that’s exactly what they would’ve needed to do.
So what is it? Well, that’s a little hard to nail down. Frankly we’d say it’s a little more like art than anything, but it does have some useful functions. Currently it shows the time, date, weather information, and various RSS feeds on its dual vacuum fluorescent displays. There’s also a real-life Geiger-Müller counter onboard, because what says Fallout more than a little radiation?
The build itself is absolutely fascinating, and [Michał] leaves no stone unturned in his comprehensive write-up. Every module of the Octoglow has its own page on his site, and each one is bristling with hardware details, schematics, and firmware documentation. Reading along you’ll run into all sorts of interesting side notes: like how he reverse engineered a wireless temperature sensor with his sound card, or devised his own ten-pin bus to interconnect all the modules.
If the Octoglow doesn’t quite scratch that Vault-Tec itch, there’s plenty more where that came from. How about this replica of the wall terminals from Fallout 4, or this radiation monitor perfect for roaming the wastelands? Don’t forget to bring along this 3D printed Thirst Zapper for protection.
It was about time (Mario Time) that Super Mario Land for the original Game Boy was revisited. The game served as the entry point into the world of portable gaming for millions, and it was an early example of the type of adventure players could expect from a handful of AA batteries. The original Game Boy system itself may have only been able to display four shades of grey, however, that never stopped players of Super Mario Land from imagining what the game would have looked like in stunning color. Now thanks to [toruzz] we no longer have to imagine, because their Super Mario Land DX ROM Hack does just that…and then some.
The Super Mario Land DX ROM hack adheres to the Game Boy Color’s 16-bit color palette, so it actually runs on real hardware. No changes to the gameplay were made and it also runs in the native 10:9 aspect ratio for the Game Boy. According to the patch readme file, it is recommended to use a legally sourced dump of the 1.0 version of Super Mario Land and utilize Lunar IPS to apply the patch. Additionally a CRC check sum is provided to ensure everyone is working from the same starting point.
Super Mario Land was a launch title for the Game Boy in 1989, but there was another handheld game system that released that year as well (the Atari Lynx). The Lynx featured a full color backlit LCD display, so it was not as if handheld game systems of the era were restricted to being monochromatic. Granted the Lynx came with a price tag nearly twice that of the Game Boy, but a transformative ROM hack such as the Super Mario Land DX one can serve almost as an alternate history. An alternate history that we all can experience now be it on a desktop or in true portable form.
To see the Super Mario Land DX ROM Hack in motion, there is the gameplay video from YouTube user Vincent Hernandez below:

In this era of 4K UHD game console graphics and controllers packed full of buttons, triggers, and joysticks, it’s good to occasionally take a step back from the leading edge. Take a breath and remind ourselves that we don’t always need all those pixels and buttons to have some fun. The LedCade is a μ (micro) arcade game cabinet built by [bobricius] for just this kind of minimalist gaming.
Using just three buttons for input and an 8×8 LED matrix for output, the LedCade can nevertheless play ten different games representing classic genres of retro arcade gaming. And in a brilliant implementation of classic hardware hacking humor, a player starts their game by inserting not a monetary coin but a CR2032 coin cell battery.
Behind the screen is a piezo speaker for appropriately vintage game sounds, and an ATmega328 with Arduino code orchestrating the fun. [bobricius] is well practiced at integrating all of these components as a result of developing an earlier project, the single board game console. This time around, the printed circuit board goes beyond being the backbone, the PCB sheet is broken apart and reformed as the enclosure. With classic arcade cabinet proportions, at a far smaller scale.
If single player minimalist gaming isn’t your thing, check out this head-to-head gaming action on 8×8 LED arrays. Or if you prefer your minimalist gaming hardware to be paper-thin, put all the parts on a flexible circuit as the Arduflexboy does.
