A Handheld Replica Sound Voltex Game

November 11, 2024 by Lewin Day No comments

Sound Voltex is a music game from Konami; in fact, it’s a whole series of arcade games! [Luke] is a big fan, so decided to build a hardware handheld to play the Unnamed Sound Voltex Clone. No—Voltex is not a typo, that’s the name.

If you’re unfamiliar, the Unnamed SDVX Clone is basically a community-built game that’s inspired by the original Konami titles. [Luke] decided to build a handheld console for playing the game, which is more akin to the arcade experience versus playing it on a desktop computer.

[Luke’s] build relies on a Raspberry Pi 4B, which donates its considerable processing power and buckets of RAM to the project. The Pi was installed into a 3D-printed case with a battery pack, touchscreen, and speakers, along with multiple arcade buttons and rotary encoders for controlling the game. Booting the Pi and clicking the icon on the desktop starts up the Unnamed Sound Voltex Clone. The game itself will be fairly familiar to any rhythm game player, though it’s a tough more sophisticated than Audiosurf. [Luke] demonstrates the gameplay on YouTube, and the finished project looks great.

We always love seeing handheld hacks, from PlayStations that never were to retro DIY creations. Video after the break.

Inside An Arcade Joystick

November 9, 2024 by Al Williams 6 Comments

If you ever played an arcade game and wondered what was inside that joystick you were gripping, [Big Clive] can save you some trouble. He picked up a cheap replacement joystick, which, as you might expect, has a bunch of microswitches. However, as you can see in the video below, there are some surprising features that make sense when you think about it.

For one, there are plates you can put on the bottom to limit the joystick’s travel depending on the game. That is, some games only want the stick to move up and down or left and right. The knobs are quite nice, and [Clive] mentions the size and thread of the knob with the idea you could use them in different applications. You can also buy replacement knobs if you don’t want to get the whole assembly.

The mechanics are rugged but straightforward. The circuit board is surprisingly stylish but also simple. Still interesting to see what’s inside one of these, even though the schematic is extremely simple.

If you need an excuse to use one of these, how about an arcade table? If you aren’t a woodworker, grab a 3D printer instead.

Here’s Code For That AI-Generated Minecraft Clone

November 9, 2024 by Donald Papp 19 Comments

A little while ago Oasis was showcased on social media, billing itself as the world’s first playable “AI video game” that responds to complex user input in real-time. Code is available on GitHub for a down-scaled local version if you’d like to take a look. There’s a bit more detail and background in the accompanying project write-up, which talks about both the potential as well as the numerous limitations.

We suspect the focus on supporting complex user input (such as mouse look and an item inventory) is what the creators feel distinguishes it meaningfully from AI-generated DOOM. The latter was a concept that demonstrated AI image generators could (kinda) function as real-time game engines.

Image generators are, in a sense, prediction machines. The idea is that by providing a trained model with a short history of what just happened plus the user’s input as context, it can generate a pretty usable prediction of what should happen next, and do it quickly enough to be interactive. Run that in a loop, and you get some pretty impressive clips to put on social media.

It is a neat idea, and we certainly applaud the creativity of bending an image generator to this kind of application, but we can’t help but really notice the limitations. Sit and stare at something, or walk through dark or repetitive areas, and the system loses its grip and things rapidly go in a downward spiral we can only describe as “dreamily broken”.

It may be more a demonstration of a concept than a properly functioning game, but it’s still a very clever way to leverage image generation technology. Although, if you’d prefer AI to keep the game itself untouched take a look at neural networks trained to use the DOOM level creator tools.

IPod Clickwheel Games Preservation Project

The iPod once reigned supreme in the realm of portable music. Hackers are now working on preserving one of its less lauded functions — gaming. [via Ars Technica]

The run of 54 titles from 2006-2009 may not have made the iPod a handheld gaming success, but many still have fond memories of playing games on the devices. Unfortunately, Apple’s Fairplay DRM has made it nearly impossible to get those games back unless you happened to backup your library since those games can’t be downloaded again and are tied to both the account and iTunes installation that originally purchased the game.

Beth Deck Is A Framework-Powered Gaming Handheld

November 3, 2024 by Navarre Bartz 22 Comments

DIY gaming handhelds have long been the purview of the advanced hacker, with custom enclosures and fiddly soldering making it a project not for the faint of heart. [Beth Le] now brings us a custom handheld for the beginner that can be assembled in 15 minutes and doesn’t require any soldering.

These claims might seem suspicious at first, but the fact that the build is powered by a Framework mainboard makes the dream seem attainable. Using an 8″ touchscreen and a rehoused mobile device controller, the 3D printed enclosure turns the PCB and battery into an interesting alternative to a Steam Deck.

[Beth] recommends waiting for the forthcoming revision 2 to make your own as she is working on refining the model. She also suggests printing in PC or PETG since PLA is too brittle and ABS warping can be an issue for tolerances with the pogo pins. In any case, this is definitely a project to keep your eye on if you enjoy gaming on the go.

As you know, we love Framework around here and the Cambrian Explosion of high-powered custom builds it’s enabled. This isn’t the first time we’ve seen a Framework-Powered handheld either. If you’re looking for a different form factor, we’ve also seen portable all-in-ones, keyboard PCs, and slabtops too.

The Phantom PSP: Crafting The Handheld Sony Never Sold

November 2, 2024 by Heidi Ulrich 7 Comments

In the world of retro gaming, some legends never die – especially the ‘phantom’ PSP, Sony’s mythical handheld that never saw the light of day. While that elusive device remains a dream, hacker and gaming wizard [Kyle Brinkerhoff] built his own – and Macho Nacho made a video about it. His creation, which also goes by the name ‘Playstation Zero’, isn’t just another handheld emulator; it’s a powerful, custom-built system that revives the classics and plays them on a portable device that feels like the future.

Driven by a hunger for the ultimate gaming experience, [Kyle] set out to blend modern tech with retro gaming magic. He started with the Raspberry Pi, loading it up with emulation software for all the iconic systems—from NES and SNES to the Sega Genesis and Game Boy. But [Kyle] didn’t just slap on an off-the-shelf emulator; he dived into the code himself, optimizing and tweaking for lightning-fast responsiveness, so each game plays like it’s running on the original hardware. That’s hacking in true form: pushing the limits of software and hardware until they work exactly the way you want them to. Best of all: he published it all open source for others to use.

In the spirit of the Geneboy—a handheld Sega Genesis built by [Downing] and featured on Hackaday back in 2012—[Kyle]’s device pairs handheld emulation with the consoles all nineties kids wanted for Christmas. To capture the tactile thrill of vintage gaming, [Kyle] went a step further by designing and 3D-printing a custom controller layout that mimics the feel of the original systems. If watching someone neatly soldering a pcb sounds relaxing to you, don’t skip the middle part of his video. Although this little beast is packed with all bells and whistles you’d expect to see on a Raspberry Pi, it does lack one serious thing: battery life. But, [Kyle] is open about that, and hopes to improve on that in a future version.

If you want to see the full build, check out the video below. Or, immediately dive into [Kyle]’s Github, order the cute Takara shell, and get started!

DIY Laser Tag Project Does It In Style

October 26, 2024 by Donald Papp 21 Comments

This DIY lasertag project designed by [Nii], which he brought to Tokyo Maker Faire back in September, is a treasure trove. It’s all in Japanese and you’ll need to visit X (formerly Twitter) to see it, but the images do a fine job of getting the essentials across and your favorite translator tool will do a fair job of the rest.

There’s a whole lot to admire in this project. The swing-out transparent OLED display is super slick, the electronics are housed on a single PCB, the back half of the grip is in fact a portable USB power bank that slots directly in to provide power, and there’s a really smart use of a short RGB LED strip for effects.

The optical elements show some inspired design, as well. An infrared LED points forward, and with the help of a lens, focuses the beam tightly enough to make aiming meaningful. For detecting hits, the top of the pistol conceals a custom-made reflector that directs any IR downward into a receiver, making it omnidirectional in terms of hit sensing but only needing a single sensor.

Want to know more? Check out [Nii]’s earlier prototypes on his website. It’s clear this has been in the works for a while, so if you like seeing how a project develops, you’re in for a treat.

As for the choice of transparent OLED displays? They are certainly cool, and we remember how wild it looks to have several stacked together.
