RuneScape GBA Controller Is A Nostalgic Mash-Up

September 2, 2019 by 4 Comments

For gamers, the early 2000s certainly stand out as a memorable era. The dawn of the 21st century ushered in the sixth generation of home video game consoles, with Sony, Nintendo, and Microsoft all releasing their systems within a few years of each other. Nintendo also released their Game Boy Advance at around the same time, representing a minor revolution for mobile gaming. On the PC front, a free-to-play MMORPG called RuneScape was redefining people’s expectations of browser-based software.

Now, thanks to modern technology and the expert guidance of [TiKevin83], these varied bits of video game history can be used in conjunction for maximum rose-tinting effect. Using homebrew software on the GameCube and a healthy collection of wires and adapters, the GBA can be used as a controller for your adventures through the realm of Gielinor. After nearly two decades, the dreams of gamers everywhere have come true.

Well, that might be a stretch. In fact, we’d wager that nobody in human history has ever looked at the GBA and thought it would be a particularly good controller for an MMORPG. Watching the video after the break, it’s not hard to see why. Using the handheld system’s digital pad to control the mouse in RuneScape looks to be precisely as clunky as you’d imagine. But of course, that’s hardly the point.

So how is it accomplished? A homebrew tool for the GameCube’s “Game Boy Player” accessory allows the GBA, when connected to the console via the appropriate adapter cable, to mimic a standard controller. Once the GBA is running in this mode, it can then be connected to the computer using a Wii U to USB adapter. Finally, the program JoyToKey is used to map the GBA’s buttons to mouse and keyboard input for “Old School” RuneScape.

If you’d like to do something similar but aren’t quite committed enough to collect up all the Nintendo-branded ephemera this method requires, you may be interested in this DIY adapter that allows the venerable GBA to be used as a standard Bluetooth controller.

NES Gets A Slick Acrylic Casemod

August 25, 2019 by 9 Comments

Those alive during the 1990s will remember the clear or “crystal” versions of various home consoles. Made with the usual injection molding processes, they usually came out somewhere closer to a smoky translucency and didn’t reveal much of the insides. [BitHead1000] likes to do things right though, and has busted out an awesome acrylic case mod for his NES.

The build starts with the disassembly of the original console, naturally, and the RF shielding is discarded in order to provide an unobstructed view of the internals. The acrylic case is then built up piece by piece, using the original case as a template. Flame polishing is used to treat the edges, and everything is stuck together using what appears to be acrylic cement. For a nice finishing touch, the cartridge door gets a frosted Nintendo logo, thanks to some careful work in the sandblasting booth.

The final product looks stunning, and the transparent case lends itself excellently to edge-lighting thanks to a few LEDs. We’ve seen [BitHead1000’s] work before, with the stunning flamethrowing N64 build. Video after the break.

Adding A Co-Processor To Help SNES Games With Slowdown

August 18, 2019 by 3 Comments

The Super Nintendo port of Gradius III is notable for being close to the arcade original, with its large, bright and colorful graphics. However, due to the limitation of the console’s hardware, the port is also well known for having constant slowdowns during gameplay, particularly during later sections. [Vitor] hacked away at the game and made a patched version of the ROM use a co-processor to eliminate those issues.

The slowdown seen here in Gradius is not uncommon to SNES players, many games of that era suffer from it when several sprites appear on the screen at once. This is partially due to the aging CPU Nintendo chose, supposedly in order to maintain NES backwards compatibility before the idea got scrapped. Unable to complete its tasks by the time the next frame needs to be shown, the hardware skips frames to let the processor catch up before it can continue. This is perceived as the aforementioned slowdown.

Around the later stage of the SNES’s life, games started using additional chips inside the cartridges in order to enhance the console’s performance. One of them is the SA1, which is a co-processor with the same core as the main CPU, only with a higher clock rate. By using it, games had more time to run through the logic and graphics manipulation before the next frame. What [Vitor] did was port those parts of Gradius III to the SA1, essentially making it just like any other enhanced cartridge from back in the day.

Unlike previous efforts we’ve seen to overclock the SNES by giving it a longer blanking time, this method works perfectly on real unmodified hardware. You can see the results of his efforts after the break, particularly around stage 2 where several bubbles fill the screen on the second video.

Perfecting A Bluetooth N64 Controller

August 17, 2019 by 1 Comment

Love it or hate it, the Nintendo 64 controller doesn’t seem to be going anywhere. Dedicated fans are still looking for ways to use the unique trilobed controller with modern systems, and they won’t be satisfied until they perfectly replicate the original experience. [Shyri Villar] has been working on perfecting a blend of original and modern hardware that looks very promising.

The project started when [Shyri] found that you could take the internals from a modern third party Bluetooth N64 controller made by 8BitDo and put them into the original controller’s case. This would give you the original buttons back, and overall a more authentic weight and feel. Unfortunately, this usually means dumping the original N64 joystick for the 8BitDo’s.

What [Shyri] wanted to do was install the 8BitDo PCB into an original N64 controller, but adapt Nintendo’s joystick to communicate with it. Unfortunately, since the original joystick used optical encoders and the 8BitDo version uses potentiometers, there’s something of a language gap.

To bridge the divide, both the X and Y dimensions of the joystick get their own PIC12F675 microcontroller and X9C103S digital potentiometer. The microcontrollers read the X and Y values from the original joystick’s encoders, and use the digital potentiometers to provide the 8BitDo with the expected analog input. Right now the electronics are held on two scraps of perfboard tucked into the side “wings” of the controller, but hopefully we’ll see a custom PCB in the future.

If you’re more interested in going back in time with your trusty N64 controller, then you might be interested in learning more about how one hacker managed to hook it up to the MSX.

Fire Breathing N64 Puts Blast Processing In The Shade

August 15, 2019 by 10 Comments

Consoles over the years have innovated, bringing new features and experiences with each subsequent generation. Rumble, motion controls and more recently VR have all come to the fore as companies vie for supremacy in the marketplace. Nobody’s really had the guts to tackle fire, though. Until now.

The case and spinning logo alone would have made the front page; the fire is simply next level. Our parents were always telling us to sit further from the TV… and now we know why.

The build is based on the Nintendo 64. The motherboard is removed from the original case, and fitted to a sheet metal enclosure of impressive craftsmanship. This allows the fitment of the machine’s party piece — twin jets of flame, triggered by an extra button on the controller. There’s also a spinning N64 logo built into the front of the case, backlit in a foreboding red — hinting to the player that this is no regular console.

The console is capable of shooting flames up to 4 feet long, and if you have to ask why, you’re likely on the wrong website. We’d love to see the jets triggered by rumble, ideally on a per player basis — making bouts of Mario Kart and Smash Brothers more perilous than ever.

As it turns out, fire’s also a great way to visualise sound waves. Video after the break.

Overclocking In An SNES Emulator

August 14, 2019 by 12 Comments

The bsnes emulator has a new overclocking mode to eliminate slowdowns in SNES games while keeping the gameplay speed accurate. We’re emulating old SNES hardware on modern machines that are vastly more powerful. Eliminating slowdowns should be trivial, right? For an emulator such as bsnes, which is written to achieve essentially pixel-perfect accuracy when emulating, the problem is decidedly non-trivial. Stick around to learn why.

The Not Quite USB-C Of Nintendo Switch Accessories

August 4, 2019 by 10 Comments

Historically gaming consoles are sold at little-to-no profit in order to entice customers with a low up-front price. The real profits roll in afterwards from sales of games and accessories. Seeking a slice of the latter, aftermarket accessory makers jump in with reverse-engineered compatible products at varying levels of “compatible”.

When the Nintendo Switch was released with a standard USB-C port for accessories, we had hoped those days of hit-or-miss reverse engineering were over, but reality fell short. Redditor [VECTORDRIVER] summarized a few parts of this story where Nintendo deviated from spec, and accessory makers still got things wrong.

Officially, Nintendo declared the Switch USB-C compliant. But as we’ve recently covered, USB-C is a big and complicated beast. Determined to find the root of their issues, confused consumers banded together on the internet to gather anecdotal evidence and speculate. One theory is that Nintendo’s official dock deviated from official USB-C dimensions in pursuit of a specific tactile feel; namely reducing tolerance on proper USB-C pin alignment and compensating with an internal mechanism. With Nintendo playing fast and loose with the specs, it makes developing properly functioning aftermarket accessories all the more difficult.

But that’s not the only way a company can slip up with their aftermarket dock. A teardown revealed Nyko didn’t use a dedicated chip to manage USB power delivery, choosing instead to implement it in software running on ATmega8. We can speculate on why (parts cost? time to market?) but more importantly we can read the actual voltage on its output pins which are too high. Every use becomes a risky game of “will this Switch tolerate above-spec voltage today?” We expect that as USB-C becomes more common, it would soon be cheapest and easiest to use a dedicated chip, eliminating the work of an independent implementation and risk of doing it wrong.

These are fairly typical early teething problems for a new complex technology on their road to ubiquity. Early USB keyboard and mice didn’t always work, and certain combination of early PCI-Express cards and motherboards caused damage. Hopefully USB-C problems — and memories of them — will fade in time as well.
