Ultimate Game And Watch Has Support For NES

December 9, 2022 by 2 Comments

We’ve talked about feature creep plenty of times around here, and it’s generally regarded as something to be avoided when designing a prototype. It might sound good to have a lot of features in a build, but this often results in more complexity and more difficulty when actually bringing a project to fruition. [Brendan] has had the opposite experience with this custom handheld originally designed for Game and Watch games, though, and he eventually added NES and Game Boy functionality as well.

As this build was originally intended just for Game and Watch games, the screen is about the size of these old games, and while it can easily mimic the monochrome LCD-style video that would have been present on these 80s handhelds, it also has support for color which means that it’s the perfect candidate for emulating other consoles as well. It’s based around a Raspberry Pi Zero 2W and the enclosure is custom printed and painted. Some workarounds for audio had to be figured out, though, since native analog output isn’t supported, but it still has almost every feature for all of these systems.

While we’ve seen plenty of custom portable builds from everything from retro consoles to more modern ones, the Game and Watch catalog is often overlooked. There are a few out there, but in this case we appreciate the feature creep that allowed this build to support Game Boy and NES games as well.

TEGA: Typescript Embedded Game Boy (Macro) Assembler

December 1, 2022 by 2 Comments

[Francis Stokes] has a real love for the original Game Boy, suggesting that owning this machine pushed him along a certain path that many of us would recognize. Developing Game Boy games isn’t particularly difficult from a hardware point of view, as you can easily buy special cartridges that have an SD card slot, allowing custom code. [Francis] had the idea of easy software development by producing a typescript hardware abstraction library, TEGA (or TypeScript Embedded Game Boy Macro Assembler). This provides a safe environment in which to play with the code, which can then be run inside an emulator such as BGB, before being deployed onto actual hardware.

The video embedded below — which we warn you now is a long one — goes into extensive justification and technical explanation of how [Francis] leverages typescript to create lots of nice features to produce safe code, whilst handling many of the Game Boy’s architectural restrictions, as well as the weirdness of the Sharp SM83 processor that powers it. We particularly liked the built-in support for on-the-fly asset compression, since every byte matters in the meager 32 Kb system, it’s nice not to have to think about it all the time! After discussing TEGA, the Game Boy hardware, the ins and outs of a demo game Block Jump, and then how to debug with BGB, we’re pretty confident many of you will be in a strong position to bust out a Game Boy application in the future!

As an aside, we did also stumble upon a new hardware guide provided by Finnish programmer and Game Boy superfan [Joonas Javanainen] which will help frame some of the topics [Francis] was talking about.

You may recall a little while back, the same author targeted the RISC-V using code written in typescript. After all, when you’re comfortable with a tool, you can shape it to do practically anything.

The Game Boy Color Accessory You’ve Been Waiting For

November 30, 2022 by 27 Comments

Sometimes silly projects catch our eye, and we just can’t resist covering them. Over on Hackaday.io, [solderking] realized that there was a glaring omission in the multi-game management hardware for the Game Boy Color. Obviously, it’s too mundane to carry the handheld around with a bunch of games in one’s pocket, and a hardware multi-changer would definitely improve the usability. This convenient, pocket-friendly solution allows you to dock up four cartridges at a time, and with only a little mild inconvenience, spin the whole assembly, lock in a game and load it up. What could be easier?

Constructed from a ridiculous three-tier PCB stack, with a rotating center joint, the assembly is completely passive, with the connections from the selected game cartridge passed down a series of connectors before finally entering the Game Boy via the usual edge connector. The mere fact that this works at all just shows how tolerant (and we guess, slow) older gaming platforms used to be, and just what you can get away with! Still, it’s a fun build, and it does work, which just goes to show that just because you can, then you should.

We’re no strangers to Game Boy hacks. Here’s a useful cartridge to help with developing your first program. If the old platform is just a bit too limited for you, then we’ve got you covered with a hack that wedges an iCE40 FPGA and a Pi Zero inside the case, to give a bit more oomph.

Portable Monitor Extension For Nintendo Switch

November 16, 2022 by 7 Comments

Handheld consoles are always a tradeoff between portability and screen real estate. [Pavlo Khmel] felt that the Nintendo Switch erred too much on the side of portability, and built an extension to embiggen his Switch. (YouTube)

[Khmel] repurposed a Dell XPS 12 LCD panel for the heart of this hack and attached it to an LCD controller board to serve as an external monitor for the Switch. A 3D printed enclosure envelops the screen and also contains a battery, speakers, and a dock for the console. Along the top edges, metal rails let you slide in the official Joy-Cons or any number of third party controllers, even those that require a power connection from the Switch.

Since the Switch sees this as being docked, it allows the console to run faster and at higher resolution than if it were in handheld mode. The extension lasts about 5 hours on battery power, and the Switch inside will still be fully charged if you don’t mind being constrained to its small screen while you charge it’s bigger-screened exoskeleton.

This Wii Has An Apple M1 Inside

November 9, 2022 by 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.

Luigi’s Mansion First Person Mod Brings Spooky New Perspective

October 28, 2022 by 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.

The NES Gets Its Own OS

September 28, 2022 by 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.
