MiSTer For Mortals: Meet The Multisystem 2

May 19, 2025 by Heidi Ulrich 19 Comments

If you’ve ever squinted at a DE10-Nano wondering where the fun part begins, you’re not alone. This review of the Mr. MultiSystem 2 by [Lee] lifts the veil on a surprisingly noob-friendly FPGA console that finally gets the MiSTer experience out of the tinker cave and into the living room. Developed by Heber, the same UK wizards behind the original MultiSystem, this follow-up console dares to blend flexibility with simplicity. No stack required.

It comes in two varieties, to be precise: with, or without analog ports. The analog edition features a 10-layer PCB with both HDMI and native RGB out, Meanwell PSU support, internal USB headers, and even space for an OLED or NFC reader. The latter can be used to “load” physical cards cartridge-style, which is just ridiculously charming. Even the 3D-printed enclosure is open-source and customisable – drill it, print it, or just colour it neon green. And for once, you don’t need to be a soldering wizard to use the thing. The FPGA is integrated in the mainboard. No RAM modules, no USB hub spaghetti. Just add some ROMs (legally, of course), and you’re off.

Despite its plug-and-play aspirations, there are some quirks – for example, the usual display inconsistencies and that eternal jungle of controller mappings. But hey, if that’s the price for versatility, it’s one you’d gladly pay. And if you ever get stuck, the MiSTer crowd will eat your question and spit out 12 solutions. It remains 100% compatible with the MiSTer software, but allows some additional future features, should developers wish to support them.

Want to learn more? This could be your entrance to the MiSTer scene without having to first earn a master’s in embedded systems. Will this become an alternative to the Taki Udon announced Playstation inspired all-in-one FPGA console? Check the video here and let us know in the comments.

Work, Eat, Sleep, Repeat: Become A Human Tamagotchi

May 12, 2025 by Heidi Ulrich 10 Comments

When [Terence Grover] set out to build a Tamagotchi-inspired simulator, he didn’t just add a few modern tweaks. He ditched the entire concept and rebuilt it from the ground up. Forget cute wide-eyed blobby animals and pixel-poop. This Raspberry Pi-powered project ditches nostalgia in favour of brutal realism: inflation, burnout, capitalism, and the occasional existential crisis. Think Sims meets cyberpunk, rendered charmingly in Python on a low-res RGB LED matrix.

Instead of hunger and poop meters, this dystopian pet juggles Maslow’s hierarchy: hunger, rest, safety, social life, esteem, and money. Players make real-life-inspired decisions like working, socialising, and going into education – each affecting the stats in logical (and often unfair) ways. No free lunch here: food requires money, money requires mind-numbing labour, and labour tanks your rest. You can even die of overwork à la Amazon warehouse. The UI and animation logic are all hand-coded, and there’s a working buzzer, pixel-perfect sprite movement, and even mini-games to simulate job repetition.

It’s equal parts social commentary and pixel art fever dream. While we have covered Tamagotchi recreations some time ago, this one makes you the needy survivor. Want your own dystopia in 64×32? Head over to [Terence Grover]’s Github and fork the full open source code. We’ll be watching. The Tamagotchi certainly is.

Let The Wookie Win With This DIY Holochess Table

May 8, 2025 by Tyler August 9 Comments

If you have seen Star Wars, you know what is being referenced here. Holochess appeared as a diversion built into the Millennium Falcon in the very first movie, way back in 1977. While not quite as iconic a use of simulated holograms as tiny Princess Leia begging for hope, it evidently struck a chord with [Maker Mac70], given the impressive effort he’s evidently gone through to re-create the game table from the film.

The key component of this unit is a plate from Japanese firm ASKA3D that scatters light from displays inside the table in just such a way that the diverging rays are focused at a point above its surface, creating the illusion of an image hovering in space. Or in this case, hovering at the surface of a acrylic chessboard. Granted, this technique only works from one viewing angle, and so is not a perfect recreation of a sci-fi holoprojector. But from the right angle, it looks really good, as you can see in the video below.

There are actually six SPI displays, driven by an Arduino GIGA, positioned and angled to project each character in the game. Placing two of the displays on 3D printed gantries allows them to move, allowing two creatures to battle in the center of the table. As [Maker Mac70] admits, this is quite a bit simpler than the Holochess game seen in the film, but it’s quite impressive for real world hardware.

If this all seems a little bit familiar, we covered an earlier floating display by [Maker Mac70] last year. This works on similar principles, but uses more common components which makes the technique more accessible. If chess isn’t your forte, why not a volumetric display that plays DOOM? If you’re interested in real holograms, not Sci-Fi, our own [Maya Posch] did a deep dive you may find interesting. Continue reading “Let The Wookie Win With This DIY Holochess Table” →

AI Brings Play-by-Play Commentary To Pong

May 6, 2025 by Al Williams 6 Comments

While most of us won’t ever play Wimbledon, we can play Pong. But it isn’t the same without the thrill of the sportscaster’s commentary during the game. Thanks to [Parth Parikh] and an LLM, you can now watch Pong matches with commentary during the game. You can see the very cool result in the video below — the game itself starts around the 2:50 mark. Sadly, you don’t get to play. It seems like it wouldn’t be that hard to wire yourself in with a little programming.

The game features multiple AI players and two announcers. There are 15 years of tournaments, including four majors, for a total of 60 events. In the 16th year, the two top players face off in the World Championship Final.

There are several interesting techniques here. For one, each action is logged as an event that generates metrics and is prioritized. If an important game event occurs, commentary pauses to announce that event and then picks back up where it left off.

We really want to see a one- or two-player human version of this. Please tell us if you take on that challenge. Even if you don’t write it, maybe the AI can write it for you.

Restoration Of Six-Player Arcade Game From The Early 90s

April 21, 2025 by Bryan Cockfield 9 Comments

Although the video game crash of the mid-80s caused a major decline in arcades from their peak popularity, the industry didn’t completely die off. In fact, there was a revival that lasted until the 90s with plenty of companies like Capcom, Midway, SEGA, and Konami all competing to get quarters, francs, loonies, yen, and other coins from around the world. During this time, Namco — another game company — built a colossal 28-player prototype shooter game. Eventually, they cut it down to a (still titanic) six-player game that was actually released to the world. [PhilWIP] and his associates are currently restoring one of the few remaining room-sized games that are still surviving.

Restoring An Abandoned Game Boy Kiosk

April 18, 2025 by Maya Posch 8 Comments

Back in the olden days, there existed physical game stores, which in addition to physical games would also have kiosks where you could try out the current game consoles and handhelds. Generally these kiosks held the console, a display and any controllers if needed. After a while these kiosks would get scrapped, with only a very few ending up being rescued and restored. One of the lucky ones is a Game Boy kiosk, which [The Retro Future] managed to snag after it was found in a construction site. Sadly the thing was in a very rough condition, with the particle board especially being mostly destroyed.

These Game Boy kiosks also featured a special Game Boy, which – despite being super rare – also was hunted down. This led to the restoration, which included recovering as much of the original particle board as possible, with a professional furniture restore ([Don]) lending his expertise. This provides a master class in how to patch up damaged particle board, as maligned as this wood-dust-and-glue material is.

The boards were then reassembled more securely than the wood screws used by the person who had found the destroyed kiosk, in a way that allows for easy disassembly if needed. Fortunately most of the plastic pieces were still intact, and the Game Boy grey paint was easily matched. Next was reproducing a missing piece of art work, with fortunately existing versions available as reference. For a few missing metal bits that held the special Game Boy in place another kiosk was used to provide measurements.

After all this, the kiosk was powered back on, and it was like 1990 was back once again, just in time for playing Tetris on a dim, green-and-black screen while hunched half into the kiosk at the game store.

GK STM32 MCU-Based Handheld Game System

April 16, 2025 by Maya Posch 8 Comments

These days even a lowly microcontroller can easily trade blows with – or surpass – desktop systems of yesteryear, so it is little wonder that DIY handheld gaming systems based around an MCU are more capable than ever. A case in point is the GK handheld gaming system by [John Cronin], which uses an MCU from relatively new and very capable STM32H7S7 series, specifically the 225-pin STM32H7S7L8 in TFBGA package with a single Cortex-M7 clocked at 600 MHz and a 2D NeoChrom GPU.

Coupled with this MCU are 128 MB of XSPI (hexa-SPI) SDRAM, a 640×480 color touch screen, gyrometer, WiFi network support and the custom gkOS in the firmware for loading games off an internal SD card. A USB-C port is provided to both access said SD card’s contents and for recharging the internal Li-ion battery.

As can be seen in the demonstration video, it runs a wide variety of games, ranging from DOOM (of course), Quake, as well as Command and Conquer: Red Alert and emulators for many consoles, with the Mednafen project used to emulate Game Boy, Super Nintendo and other systems at 20+ FPS. Although there aren’t a lot of details on how optimized the current firmware is, it seems to be pretty capable already.
