A Nintendo 64 console with modern hardware internals

N64 Mini PC Conversion Includes All The Trimmings

November 18, 2021 by Chris Wilkinson 8 Comments

We’ve seen quite a few retro gaming consoles physically modded to house modern emulation hardware, but the NUC-64 by [RetroModder] stands out as one of the most impressive Nintendo 64 guttings that we’ve seen to date.

Observed from the front, the NUC-64 almost resembles a stock Nintendo console. The project’s name is printed across the vestigial cartridge slot, and two suspiciously modern wireless networking antennas can be seen poking out from the back. The console’s modifications are fully revealed when looking at it from the rear – gone is the power brick socket, which now houses the I/O for the replacement motherboard. A custom 3D printed I/O shield keeps everything looking neat and tidy.

Internally, the new hardware is no slouch. The Intel NUC is a small-form-factor PC, and this miniature battlestation sports an 1.6GHz Intel N3700 Pentium processor, 4GB of DDR3 RAM, WiFi/Bluetooth connectivity and an M.2 SSD. This hardware runs circles around the original Nintendo 64, and is more than capable of emulating games from that system.

Most total conversions would call it a day here, however [RetroModder] has taken it a step further by producing a custom PCB that neatly ties together the console’s front I/O. Most importantly, two Mayflash N64-to-USB converters means that your favorite 1990s games can be enjoyed with the original controllers. The original power LED and reset switch are present, as is the sliding power switch which retains its original purpose, thanks to a simple 555 circuit that sends the expected power-on and power-off signals to the motherboard with each slide of the power switch. Additionally, a system of 3D printed mounts and brackets keeps everything secure inside the case.

All the build details can be found here. The NUC-64 follows on from last month’s GamecubePC. The build quality and attention to detail makes this conversion rather special, and it’s clear that a lot of care and planning was taken to pull this off. Hopefully the original N64 hardware can be repurposed as well, perhaps as a new portable console?

Video Gaming Like It’s 1983: New Game Cartridges From Atari

November 18, 2021 by Jenny List 19 Comments

If you remember anything from 1983, it’s likely to be some of the year’s popular culture highlights, maybe Return of the Jedi, or Michael Jackson’s Thriller. For anyone connected with the video gaming industry though, it’s likely that year will stick in the mind for a completely different reason, as the year of the infamous Great Video Games Crash. Overcapacity in the console market coupled with a slew of low quality titles caused sales to crash and a number of companies to go out of business, and the console gaming world would only recover later in the decade with the arrival of the Japanese 8-bit consoles from Nintendo and Sega. You might expect Atari to shy away from such a painful period of their history, but instead they are embracing it as part of their 50th anniversary and launching three never-released titles on cartridges for their 8-bit 2600 console.

The three games, Yars’ Return, Aquaventure, and Saboteur, are all unreleased titles from back in the day that never saw publication because of the crash, and are being released as limited edition specials through AtariXP, a new venture that the company says will offer “previously unreleased titles from Atari’s expansive library, rare-and-hard-to-find Atari IP physical media, and improved versions of classic games“. It’s fairly obviously an exercise in satisfying the collector’s market rather than one of video game publishing, but it will be interesting to see what emerges. In particular we hope someone will tear down one of these cartridges; will they find a set of old-school EPROMs inside or an EPROM emulator sporting a microcontroller and other 2020s trickery?

This is not of course the first time we’ve reported on collectable 2600 cartridges, but these ones haven’t spent 30 years in a landfill site.

Cramming A DS Inside A Gameboy

November 16, 2021 by Matthew Carlson 4 Comments

Many holiday recipes and console hacks share a common theme: cramming a thing inside another thing. Whether it’s turducken or a Nintendo DS inside a Gameboy, the result is always unexpected. The chassis for this mod is a humble Gameboy color with a Gameboy SP screen tackled on the top to serve as the secondary display. Unfortunately, this mod lost touch screen functionality, limiting some of the games you can play.

[TheRetroFuture] received the custom handheld from [GameboyCustom], which was somewhat damaged in shipping. The original screw mounts had to be removed and the case glued back together to fit the DS motherboard. So for [TheRetroFuture] to get inside to start troubleshooting involved a razor blade and patience. Testing various points and swapping components got [TheRetroFuture] closer to the root problems. The fix ended up being a few wires that came loose during shipping. Finally, after reseating a display connection and some careful soldering, it booted and started playing games.

Overall, it’s pretty impressive to see Mario Kart DS running on both screens on the tiny handheld. But you might be asking, why? Why shove one handheld inside another handheld? Sometimes it’s to gain new functionality like this Raspberry Pi inside a PSP body. Sometimes, it’s just because we can. Video after the break.

Stardew Valley Preferences Bot Is A Gift To The Player

November 14, 2021 by Kristina Panos 1 Comment

It seems like most narrative games have some kind of drudgery built in. You know, some tedious and repetitious task that you absolutely must do if you want to succeed. In Stardew Valley, that thing is gift giving, which earns you friendship points just like in real life. More important than the giving itself is that each villager has preferences — things they love, like, and hate to receive as gifts. It’s a lot to remember, and most people don’t bother trying and just look it up in the wiki. Well, except for Abigail, who seems to like certain gemstones so much that she must be eating them. She’s hard to forget.

[kutluhan_aktar]’s villager gift preferences bot is a fun and fantastic use of OpenCV. This bot uses a LattePanda Alpha 864s, which is a single-board computer with an Arduino Leonardo built in. It works using template matching, which is basically a game of Where’s Waldo? for computers.

Given a screenshot of each villager in various positions, the LattePanda recognizes them among a given game scene, then does a lookup of their birthday and preferences which the Leonardo prints on a 3.5″ LCD screen. At the same time, it alerts the player with a buzz and big green LED. Be sure to check it out in action after the break.

In Animal Crossing, the drudgery amounts to pressing the A button while catching shooting stars. That’s not a huge problem for a Teensy.

Arcade Machine Pack And Play

November 14, 2021 by Matthew Carlson 3 Comments

There’s something about the large imposing wooden box of an arcade machine that lends a confident presence to a room. The problem with a tall and heavy box is that it takes up quite a bit of space and readily draws the eye. So [Alexandre Chappel] set out to avoid that and build an arcade machine that could hide in plain sight.

Extra points awarded for neat wiring on the inside.

The idea is a wooden box hung on the wall that folds up when not in use. [Alex] starts with Baltic birch plywood cut into the panels. Next, he applies edge banding (a thin veneer with some glue on the backside) so that all the exposed edges look like natural wood. Next, a screen hole is routed into the face frame, allowing an LCD monitor to sit snuggly in. A combination of pocket holes and biscuits allows [Alex] to assemble everything with no visible screws or fasteners.

With the help of a 3D printer, he quickly fabricated a locking mechanism to keep the front panel attached when it folds up. The hinge is also 3D printed. The typical Raspberry Pi 4 powers this particular machine. Two french cleats hold the box onto the wall, and once the system is on the wall, we have to say it looks incredible.

If you’re looking for a smaller but more traditional arcade cabinet, why not take a look at this arcade cabinet for toddlers? Or, if you loved the solid wood look of the hidden arcade, this full-sized solid oak cabinet would be something you would enjoy. Video after the break.

Children playing a zombie shooting game on a big screen

Halloween Game Lets You Shoot Zombies With A Laser-Powered Crossbow

November 12, 2021 by Robin Kearey 1 Comment

Suppose you were looking for all the essential elements to make a great Halloween-themed shooting game. Zombies? Check. Giant “lasers”? Check. Crossbows shooting forks? We’ve got you covered. Check out “Fork The Zombies“, which was set up by [piles.of.spam] to entertain the neighborhood kids this Halloween.

The game is played on a big screen, which shows a horde of angry zombies marching toward the player, who has to shoot as many as possible before they reach the front of the screen. The weapon provided is a crossbow; when the trigger is pulled, a fork is launched and hopefully skewers one of the ghouls. The game was written using an open-source engine called Urho3D, which takes care of all the hard-core 3D and physics work, allowing the user to focus on designing the gameplay and visuals.

To give the game a bit more of a physical feel, [piles.of.spam] made an actual crossbow for the player to wield. Its handle was cut from a scrap piece of wood, using a band saw for the general shape and a CNC machine for the delicate cut-outs that hold a laser pointer, an ESP32 and a microswitch-based trigger. The laser shines onto the game screen, while the ESP32 sends out a data packet over WiFi when the trigger is pulled.

The location of the shot is tracked using a clever trick: a webcam is pointed at the screen, with a red color filter in front. This way, it only sees the red laser dot moving across the screen. The resulting image is processed using the Python OpenCV library, which provides functions to convert the relative motion of the pointer on the screen to an absolute position along the playing field.

The computing hardware consists of a pair of Jetson Nano boards, which sport quad-core ARM A57 CPUs as well as powerful graphics hardware to generate the game’s visuals. The end result is impressive, especially given the fact that all of this was designed and built in just three weeks. It was apparently a great hit with its intended audience, as visitors queued to try their hand at shooting the hungry zombies.

Laser pointers are an obvious tool for creating shooting games: we’ve seen ones with a single round target, a set of shapes set up around you, and even metal cans that fall over and stand up again. But if you need to protect yourself in case of an actual zombie apocalypse, a slingshot that shoots knives might be more useful.

LEDBOY Is A Retro-Modern Handheld Game

November 11, 2021 by Zoe Skyforest 3 Comments

Back in the 1970s, there were a few LED-based games on the market that were quickly superseded by the rise of LCDs and other fancier technologies. However, [grossofabian] wanted to recreate that classic style of game but with more modern hardware. The result is the LEDBOY, a colorful handheld game built in tribute to that era.

The handheld is based around the ATtiny 1614 microcontroller, driving a 10×10 array of NeoPixel Nano 2427 LEDs, named for their small 2.4 mm x 2.7 mm form factor. They’re RGB, too, so there’s lots of wonderful colors to play with.

Wrapped up in a neat enclosure with a rechargeable 130 mAh lithium-ion battery and some simple tactile buttons, it’s a tidy little handheld game console. Add in the CH340C chip for USB to serial duties, and it’s easy to program with the Arduino IDE, too.

Code is available on Github for those keen to take a closer look. Amusingly, the project bears a striking resemblance to a similarly-named build we featured just under 12 years ago. Time is a flat circle, and the video, my friends, is after the break.
