A Real Working Lego NES

September 9, 2020 by Lewin Day 3 Comments

Lego is an entry into the world of engineering for many a youngster, and an enjoyable pursuit for many more. These days, high quality kits are available to make everything from the Tower of Pisa to Nintendo’s venerated NES console. [TronicsFix] picked up the latter set, and decided it needed to be fully functional.

Consisting of 2646 pieces, the official Lego NES is a faithful recreation of the original, albeit at approximately 80% of the size. After building the kit to spec, [TronicsFix] noted that there was no way a cartridge would fit in the slot.

Given this failing, a ground-up rebuild was in order. Starting with the internals from an original NES, [TronicsFix] set about building an appropriately sized base and working from there. Supports were built to mount the various components, with the controller ports being particularly well done, and the video output and power switches being a little more tricky. The many cosmetic pieces from the official kit came in handy here, giving the final product the aesthetic touches it needed to fit the bill.

The final result is an authentic, functional NES in a LEGO case. [TronicsFix] demonstrates as such, showing the console playing Super Mario 3. Nintendo consoles remain a favorite amongst modders; some going so far as to build fire-breathing creations. Video after the break.

WiiBoy Color Is Exactly What It Sounds Like

September 2, 2020 by Lewin Day 16 Comments

Anyone can go out and buy a handheld console, and if you want to be the cool kid on the school bus, you can always ask your parents to take you out to get one. But if you want real street cred that lasts through your adult years, you’ve gotta put something together yourself. [GingerOfMods] has done just that with the Wiiboy Color.

Yes, it’s another home-console-turned-portable, and it’s perfomed with exquisite execution. The Wii motherboard is cut and sliced to the absolute bare minimum, as the aim was to build the entire system to the rough form factor of the original Game Boy Color. Custom PCBs were then used to link the chopped ‘board to peripherals, such as the USB drive used to load games and the circuitry from a Gamecube controller. The screen is a beautiful looking 3.5″ IPS LCD, running at 480p and originally intended for use as an automotive backup camera. Battery life is around 2-3 hours, with a USB-C port included for easy charging. More details are included on the forum build log.

It’s a tidy build, and the 3D printed case, Switch joysticks and DS Lite buttons give it a near-production quality finish. [GingerOfMods] intends to build more for commissions, though expect a hefty price tag given the labor and custom work involved. We’ve seen other portable Wiis before too, like this tightly-packed Kapton-heavy build. Video after the break.

Retro Game Bow Tie

August 4, 2020 by Orlando Hoilett 4 Comments

[Greg] loves hacking his bow ties. Back in high school, he added some bright RGB LEDs to the bow tie he wore to prom and even won the male best-dressed award. Recently he decided to try another bow tie hack, this time giving his tie some retro arcade game feels.

He decided to use an ATtiny85 and to experiment doing some more lower-level programming to refresh his skills. He wrote all his libraries from scratch which really helped him learn a lot about the ATtiny in the process. This also helped him make sure his code was as efficient as possible since he had quite a bit of memory constraints using the ATtiny85 (only 512 bytes of RAM).

He designed the body of the bow tie with wood. He fit all the electronics inside the body while allowing the ATtiny to protrude out of the body giving his bow tie some wanted hacker aesthetic. Of course, he needed to access the toggle switch to play the game, so he made a slot for that as well.

Nice addition to the electronics bow tie collection on Hackaday. Really aesthetic design if you ask us. And you know how much we love retro games.

Remote Code Execution On The N64

July 6, 2020 by Lewin Day 4 Comments

Some like to garden in their spare time, while others prefer to smoke cigars or fold complicated origami figurines. Security researcher ~~[grifter]~~ [CTurt] seems to enjoy cracking consoles instead, and had a go at exploiting the Nintendo 64 over an obscure modem interface.

The 1990s were a wild time, where games shipped in cartridges. This format opened up crazy possibilities to add additional hardware to the cartridge itself. Perhaps most famously, Nintendo packed in the SuperFX chip to enable 3D graphics on the Super Nintendo. Later on, the N64 game Morita Shogi 64 shipped with an entire telephone modem in the cartridge itself. The resulting exploit is therefore dubbed “shogihax”.

Armed with a dodgy GameShark and a decompiler, [CTurt] set to work. Through careful parsing of the code, they were able to find a suitable overflow bug in the game when using the modem. Unlike more pedestrian savegame hacks, this not only allowed for the execution of arbitrary code but also the modem interface means that it’s possible to continually stream more data to the console on an ad-hoc basis.

It’s a great hack that takes advantage of a relatively accessible cartridge, rather than relying on more obscure hardware such as the N64DD modem or other rarities. We’ve seen other N64 homebrew hacks before, too. Video after the break.

Thanks to [grifter] for the tip!

Finding A Secret Message From A Gaming Legend

July 4, 2020 by Tom Nardi 6 Comments

Satoru Iwata is perhaps best remembered for leading Nintendo through the development of the DS and Wii, two wildly successful systems which undeniably helped bring gaming to a wider and more mainstream audience. But decades before becoming the company’s President in 2002, he got his start in the industry as a developer working on many early console and computer games. [Robin Harbron] recently decided to dig into one of the Iwata’s earliest projects, Star Battle for the VIC-20.

Finding the message was easy, if you knew were to look.

It’s been known for some time that Iwata, then just 22 years old, had hidden his name and a message in the game’s source code. But [Robin] wondered if there was more to the story. Looking at the text in memory, he noticed the lines were actually null-terminated. Realizing the message was likely intended to get printed on the screen at one point during the game’s development, he started hunting for a way to trigger the nearly 40 year old Easter Egg.

As it turns out, it’s hidden behind a single flag in the code. Just change it from 0 to 1, and the game will display Iwata’s long-hidden credit screen. That proved the message was originally intended to be visible to players, but it still didn’t explain how they were supposed to trigger it during normal game play.

That’s where things really get interesting. As [Robin] gives us a guided tour through Star Battle’s inner workings, he explains that Iwata originally intended the player to hit a special combination of keys to tick over the Easter Egg’s enable flag. All of the code is still there in the commercial release of the game, but it’s been disabled. As Iwata’s life was tragically cut short in 2015 due to complications from cancer, we’ll perhaps never know the reason he commented out the code in question before the game was released. But at least we can now finally see this hidden message from one of gaming’s true luminaries.

Last time we heard from [Robin], he’d uncovered a secret C64 program hidden on a vinyl record. With his track record so far, we can’t wait to see what he digs into next. Continue reading “Finding A Secret Message From A Gaming Legend” →

No, The Nintendo Leak Won’t Help Emulator Developers, And Here’s Why

May 21, 2020 by Erin Pinheiro 34 Comments

If you haven’t heard from other websites yet, earlier this year a leak of various Nintendo intellectual properties surfaced on the Internet. This included prototype software dating back to the Game Boy, as well as Verilog files for systems up to the Nintendo 64, GameCube and Wii. This leak seems to have originated from a breach in the BroadOn servers, a small hardware company Nintendo had contracted to make, among other things, the China-only iQue Player.

So, that’s the gist of it out of the way, but what does it all mean? What is the iQue Player? Surely now that a company’s goodies are out in the open, enthusiasts can make use of it and improve their projects, right? Well, no. A lot of things prevent that, and there’s more than enough precedent for it that, to the emulation scene, this was just another Tuesday.

Teardown: Generation NEX

May 11, 2020 by Tom Nardi 13 Comments

Today if you wanted a little gadget to sit on your shelf and let you play classic games from the early console era, you’d likely reach for the Raspberry Pi. With slick emulator front-ends like RetroPie and DIY kits available on Amazon, you don’t even need to be a technical wizard or veteran penguin wrangler to set it up. If you can follow an online tutorial, you can easily cram the last few decades of gaming into a cheap and convenient package.

But things were a bit different back in 2005. There weren’t a lot of options for playing old games on the big screen, and what was out there tended to be less than ideal. You could hack an original Xbox or gut an old laptop to make an emulation box that could comfortably blend in with your DVD player, but that wasn’t exactly in everyone’s wheelhouse. Besides, what if you had the original cartridges and just wanted to play them on a slightly more modern system?

I’m willing to bet whoever wrote this owns a katana.

Enter Messiah, and their Generation NEX console. As you might have gathered from their ever-so-humble name, Messiah claimed their re-imagined version of the Nintendo Entertainment System would “Bring Gaming Back to Life” by playing the original cartridges with enhanced audio and visual clarity. It also featured integrated support for wireless controllers, which at the time was only just becoming the standard on contemporary consoles. According to the manufacturer, the Generation NEX used custom hardware based on the “NES algorithm” that offered nearly 100% game compatibility.

Unfortunately, the system was a complete bomb. Despite Messiah’s claims, the Generation NEX ended up being yet another “NES-on-a-chip” (NOAC) clone, and a pretty poor one at that. Reviewers at the time reported compatibility issues with many popular titles, despite the fact that they were listed as working on Messiah’s website. The touted audio and video improvements were nowhere to be found, and in fact many users claimed the original NES looked and sounded better in side-by-side comparisons.

It didn’t matter how slick the console looked or how convenient the wireless controllers were; if the games themselves didn’t play well, the system was doomed. Predictably the company folded not long after, leaving owners stuck with the over-priced and under-performing consoles. Realistically, most of them ended up in landfills. Today we’ll take a look inside a relatively rare survivor and see just what nostalgic gamers got for their money in 2005.
