This Wii Has An Apple M1 Inside

November 9, 2022 by Navarre Bartz 8 Comments

The conveniently tiny logic board of the M1 Mac mini has lead to it giving the Mini ITX format a run for its money in case mods. The latest example of this is [Luke Miani]’s M1 Wii. (Youtube via 9to5Mac)

[Miani] chose the Wii as a new enclosure for this Mac mini given its similar form factor and the convenient set of doors in the top to maintain access to the computer’s I/O, something he wasn’t able to do with one of his previous M1 casemods. The completed build is a great stealth way to have a Mac mini in your entertainment center. [Miani] even spends the last several minutes of the video showing the M1 Wii running Wii, GameCube, and PS2 games to really bring it full circle.

A Microsoft Surface power brick was spliced into the original Wii power cable since the Wii PSU didn’t have enough wattage to supply the Mac mini without significant throttling. On the inside, the power runs through a buck converter before making its way to the logic board. While the Mini’s original fan was too big to fit inside the Wii enclosure, a small 12V fan was able to keep performance similar to OEM and much higher than running the M1 fanless without a heat spreader.

How Those NES DIP Chips Were Reduced To QFNs

November 7, 2022 by Jenny List 26 Comments

The world of console modding leads us to some extremely impressive projects, and a recent one we featured of note was a portable NES produced by [Redherring32]. It was special because the original NES custom DIP chips had been sanded down to something like a surface-mount QFN package. Back when our colleague [Arya] wrote up the project there wasn’t much information, but since then the full details have been put up in a GitHub repository. Perhaps of most interest, it includes a full tutorial for the chip-sanding process.

To take irreplaceable classic chips and sand them down must take some guts, but the premise is a sound enough one. Inside a DIP package is a chip carrier and a web of contact strips that go to the pins, this process simply sands away the epoxy to expose those strips for new contacts. The result can then be reflowed as would happen with any QFN, and used in a new, smaller NES.

Along the way this provides a fascinating insight into DIP construction that most of us never see. If any of you have ever managed to fatigue a pin off a DIP, you’ll also no doubt be thinking how the technique could be used to reattach a conductor.

Luigi’s Mansion First Person Mod Brings Spooky New Perspective

October 28, 2022 by Drew Littrell 2 Comments

The Nintendo GameCube in many ways defied expectations. It was purple, it had buttons shaped like beans, and it didn’t launch with a Mario game. What we got instead was the horror-adjacent ghost adventure game starring Mario’s brother — Luigi’s Mansion. The game was a graphical showpiece for the time, however, the camera angles were all fixed like an early Resident Evil game. Not satisfied with playing within those bounds, modder [Sky Bluigi] created a first person camera patch for the game that finally let players see why Luigi was so freaked out all the time.

The patch dubbed Luigi’s Mansion FPO (First Person Optimized) does a lot to drive home the game’s child-friendly, spooky aesthetic. Along with the ability to explore environments with a new lens, it provides the ability to turn the flashlight on and off manually if you want. Though the most impressive part of Luigi’s Mansion FPO is that it runs on real hardware. All that’s needed to play the mod is clean image of the North American release of Luigi’s Mansion and a .xdelta patching utility like Delta Patcher. GameCube games can be ripped directly to a USB thumb drive using a soft-modded Nintendo Wii console running Clean Rip or similar backup tool.

Luigi’s Mansion FPO actually provides a collection of patches that offer revised controls and increased field of view depending on which patch is used. The original game had inverted controls for aiming Luigi’s ghost vacuum, so the “Invert C-Stick Controls” patch will install a more modern aiming scheme where up on the right stick will aim upwards and vice versa. The “Better FOV” pulls the camera a little further back from where Luigi’s head would be while the original aiming scheme is retained. Though no matter which patch you decide to go with, a mod like this is always a good excuse to revisit a cult classic.

Nintendo Switch Stock Dock Imperfect? Mill Your Own!

October 4, 2022 by Arya Voronova 3 Comments

Despite the seat of honor it enjoys in literally millions of households, the official Nintendo Switch Dock is certainly far from perfect. For one, it’s not milled out of a hefty block of aluminum. A less apparent but no less important issue is that the ports are positioned kind of awkward – [Kevin] from Modified believes that the USB ports should be facing the front side, while the HDMI, Ethernet, and charging inputs should be on the backside — a reasonable position. He set out to fix both of these problems at the same time, and tells us the CNC-heavy rebuild story in a short but captivating video.

The original dock consists of two PCBs, and these two boards are the only thing [Kevin] didn’t redesign from scratch. As they’re connected with a flexible cable, he could freely rotate and thus completely reposition the ports-equipped board without soldering. He added some standoffs to secure this board to the case, and after 3D printing a few iterations for test-fitting, the milling went on for all of us to marvel at.

The resulting dock is pretty, functional, and even has some extra features — for instance, the “i” in the embossed Nintendo logo lights up when the dock is in use. In no small part due to the Nintendo logo, we don’t expect this one to grace store shelves, but we hope that it provides inspiration to other makers to do their builds. If you like this rebuild and crave more, whether you’re looking for inspiration, CNC work insights, or pretty milling videos, [Kevin]’s milled Xbox case project is an excellent “Watch next” choice.

Making A Handheld NES By Turning DIP Chips Into…QFN?

October 2, 2022 by Arya Voronova 51 Comments

You can achieve a lot with a Dremel. For instance, apparently you can slim the original NES down into the hand-held form-factor. Both the CPU and the PPU (Picture Processing Unit) are 40-pin DIP chips, which makes NES minification a bit tricky. [Redherring32] wasn’t one to be stopped by this, however, and turned these DIP chips into QFN-style-mounted dies (Nitter) using little more than a Dremel cutting wheel. Why? To bring his TinyTendo handheld game console project to fruition, of course.

DIP chip contacts go out from the die using a web of metal pins called the leadframe. [Redherring32] cuts into that leadframe and leaves only the useful part of the chip on, with the leadframe pieces remaining as QFN-like contact pads. Then, the chip is mounted onto a tailored footprint on the TinyTendo PCB, connected to all the other components that are, thankfully, possible to acquire in SMD form nowadays.

This trick works consistently, and we’re no doubt going to see the TinyTendo being released as a standalone project soon. Just a year ago, we saw [Redherring32] cut into these chips, and wondered what the purpose could’ve been. Now, we know: it’s a logical continuation of his OpenTendo project, a mainboard reverse-engineering and redesign of the original NES, an effort no doubt appreciated by many a NES enthusiast out there. Usually, people don’t cut the actual chips down to a small size – instead, they cut into the mainboards in a practice called ‘trimming’, and this practice has brought us many miniature original-hardware-based game console builds over these years.

ConnectedNES Brings Twitter Into Super Mario Bros World

October 2, 2022 by Arya Voronova 6 Comments

Back in 2016, artist and video game historian [Rachel Weil (HXLNT)] was hanging out with her friend and hacking on console stuff, as friends do. [Rachel] was galvanized by the idea of having an iconic game like Super Mario Bros be interrupted by push notifications, and set out to bring a Twitter feed to her NES gaming experience. What she ended up with is ConnectedNES — a charming combination of a custom Twitter modem and a hacked Super Mario Bros ROM, creating a social media experience you have to see for yourself.

The technical side is as immaculate as the visuals. Data is transferred to the NES through the controller port using a Particle Photon that’s emulating a NES controller, and everything is encased in an adorable shell made out of yarn needlework.

The Photon currently taps into the Twitter feed through a proxy server run locally, and listens for tweets with specific keywords, relaying them to the ROM through mimicking controller port inputs. The ROM, now bearing the name Social Media Bros, went through some careful assembly trimming work. In particular, [Rachel] had to sacrifice Green Mario to the bit bucket gods.

Playing this game has to be quite the experience. Thankfully, source code for everything — the proxy server, the Photon firmware and the NES ROM — is on GitHub for all of us NES enthusiasts to hack at. If simply reading the feed is not enough, you can send tweets from your NES as well.

The NES Gets Its Own OS

September 28, 2022 by Bryan Cockfield 20 Comments

Until recently, most video game systems didn’t need their own operating systems in order to play games. Especially in the cartridge era — the games themselves simply ran directly on the hardware and didn’t require the middleman of an operating system for any of the functionality of the consoles. There were exceptions for computers that doubled as home computers such as the Commodore, but systems like the NES never had their own dedicated OS. At least, until [Inkbox] designed and built the NES-OS.

The operating system does not have any command line, instead going directly for a graphical user interface. There are two programs that make up the operating system. The first is a settings application which allows the user to make various changes to the appearance and behavior of the OS, and the second is a word processor with support for the Japanese “Family Keyboard” accessory. The memory on the NES is limited, and since the OS loads entirely into RAM there’s only enough leftover space for eight total files. Those files themselves are limited to 832 bytes, which is one screen’s worth of text without scrolling.

While it might seem limited to those of us living in the modern era, the OS makes nearly complete use of the available processing power and memory of this 1980s system that was best known for Super Mario Bros. and Duck Hunt. It’s an impressive build for such a small package, and really dives into a lot of the hardware and limitations when building software for these systems. If you need more functionality than that, we’d recommend installing Linux on the NES Classic instead.
