NES Classic Edition – Controller Mod

December 29, 2016 by Lewin Day 12 Comments

The Nintendo Classic Mini took the world by storm this year — finally, an NES in a cute, tiny package that isn’t 3D printed and running off a Raspberry Pi! It’s resoundingly popular and the nostalgic set are loving it. But what do you do when you’re two hours deep into a hardcore Metroid session and you realize you need to reboot and reload. Get off the couch? Never!

[gyromatical] had already bought an Emio Edge gamepad for his NES Mini. A little poking around inside revealed some unused pads on the PCB. Further investigation revealed that one pad can be used to wire up a reset button, and two others can be used to create a home switch. Combine this with the turbo features already present on the Emio Edge, and you’ve got a pretty solid upgrade over the stock NES Mini pad. Oftentimes, there’s extra functionality lurking inside products that manufacturers have left inactive for the sake of saving a few dollars on switches & connectors. It’s always worth taking a look inside.

Now, back in 2006, the coolest hack was running Linux on everything — and somebody’s already trying to get Linux on the NES Mini.

Thwomp Drops Brick On Retro Gaming

December 3, 2016 by Rich Hawkes 19 Comments

[Geeksmithing] wanted to respond to a challenge to build a USB hub using cement. Being a fan of Mario Brothers, a fitting homage is to build a retro-gaming console from cement to look just like your favorite Mario-crushing foe. With a Raspberry Pi Zero and a USB hub embedded in it, [Geeksmithing] brought the Mario universe character that’s a large cement block — the Thwomp — to life.

[Geeksmithing] went through five iterations before he arrived at one that worked properly. Initially, he tried using a 3D printed mold; the cement stuck to the plastic ruining the cement on the face. He then switched to using a mold in liquid rubber (after printing out a positive model of the Thwomp to use when creating the mold). But the foam board frame for the mold didn’t hold, so [Geeksmithing] added some wood to stabilize things. Unfortunately, the rubber stuck to both the foam board and the 3D model making it extremely difficult to get the model out.

Next up was regular silicone mold material. He didn’t have enough silicone rubber to cover the model, so he added some wood as filler to raise the level of the liquid. He also flipped the model over so that he’d at least get the face detail. He found some other silicone and used it to fill in the rest of the mold. Despite the different silicone, this mold worked. The duct tape he used to waterproof the Raspberry Pi, however, didn’t. He tried again, this time he used hot glue – a lot of hot glue! – to waterproof the Pi. This cast was better, and he was able to fire up the Pi, but after a couple of games his controller stopped working. He cracked open the cement to look at the Pi and realized that a small hole in the hot glue caused a leak that shorted out the USB port on the Pi. One last time, he thought, this time he used liquid electrical tape to waterproof the Pi.

The final casting worked and after painting, [Geeksmithing] had a finished cement Thwomp console that would play retro games. He missed the deadline for the USB Hub Challenge, but it’s still a great looking console, and his video has a lot of detail about what went wrong (and right) during his builds. There’s a great playlist on YouTube of the other entries in the challenge, check them out along with [Geeksmithing]’s video below!

Learn Some Plastic Techniques With This SNES WiiMote Mod

November 25, 2016 by Gerrit Coetzee 11 Comments

Not all hacks have to be deeply technical. Sometimes a good show of skill is just as impressive. [lyberty5] takes two completely different hunks of plastic and somehow epoxies them into a convincing and, most impressively, reliable chimera.

While the WiiMote’s motion controls certainly caused a lot of wordy debate on the Internet when it was debuted. While everyone and their grandmother who owned a game company rushed out to copy and out-innovate it once they saw Nintendo’s hoard of dragon gold. Most game designers had other thoughts about the concept, mostly that it wouldn’t do for a platformer. So the gamer caught in the middle of it all had to rotate their grip-optimized rectangle 90 degrees and blister their thumbs on tiny buttons to play.

Linux On Your NES Classic Edition

November 13, 2016 by Jenny List 53 Comments

Nintendo look as though they may have something of a hit on their hands with their latest console offering. It’s not the next in the line of high-end consoles with immersive VR or silicon that wouldn’t have looked out of place in last year’s supercomputer, instead it’s an homage to one of their past greats. The NES Classic Edition is a reboot of the 1980s console with the familiar styling albeit a bit smaller, and 30 of the best NES games included.

You do not, however, get an original NES with a 6502 derived processor, and a stack of game cartridges. In the Classic Edition is a modern emulator, running on very modern hardware. We’re told it contains an Allwinner R16 quad-core Cortex A7 SoC, 256Mb of RAM, and 512Mb of Flash. That’s a capable system, and unsurprisingly any hacking potential it may have has attracted some interest. Reddit user [freenesclassic] for example has been investigating its potential as a Linux machine, and has put up a post showing the progress so far. It is known that there is already some form of Linux underpinning the console because Nintendo have released a set of sources as part of their compliance with the terms of the relevant open-source licences. That and the availability of a serial port via pads on the PCB gives hope that a more open distro can be installed on it.

We’re taken through the process of starting the machine up with the serial port connected to a PC, and getting it into the Allwinner FEL mode for low-level flashing work. Then we’re shown the process of loading a custom U-Boot, from which in theory a kernel of your choice can be loaded.

Of course, it’s not quite that simple. There is still some way to go before the device’s Flash can be accessed so for now, all that is possible is to use the RAM, and the current state of play has a kernel panic as it is unable to mount a filesystem. However this is a new piece of hardware in its first few days after launch, so this is very much a work in progress. We are sure that this device will in time be opened up as a fully hackable piece of hardware, and we look forward to covering the interesting things people do with it when that has happened.

If you are interested in the NES Classic, take a look at it on Nintendo’s web site. Meanwhile, here at Hackaday as a quick look at our past stories tagged “nes” shows, we’ve covered a huge number of projects involving the platform in the past.

Thanks [Doc Oct] for the tip.

Crack Mike Tyson’s Punch Out Bang Bang Passwords

November 11, 2016 by Gerrit Coetzee 5 Comments

[Bisqwit] has feelings about games that use exclamation points in his idiosyncratic walkthrough of all the nuances of the passwords in the famous Punch Out Bang Bang.

As he states in his deeply weird (though in no way wrong) channel intro, when he’s not driving a bus or teaching Israeli dance, he works hard to understand the things around him. Naturally, a mysterious phone number shaped set of digits in a favorite game was a secret worth extracting.

The digits can represent every possible state in the game. It uses a pretty simple decoding and encoding scheme, which he walks through. As he says, it all becomes clear when you can see the source code.

After working through all the quirks he is able to arbitrarily generate any state in the game and handle the exceptions (such as Nintendo USA’s phone number). You can see all his code here and try it out for yourself. Video after the break.

We’ve grown to respect [Bisqwit] as the explainer of all things console games. You will like his explanation of how to write a code emulator for an NES CPU.

One Home Made NES To Rule Them All

October 27, 2016 by Jenny List 10 Comments

The Nintendo Entertainment System, or Famicom depending on where in the world you live, is a console that occupies a special place in the hearts of people of a certain age. If you lived in a country that Nintendo didn’t ship its consoles to in the late ’80s and early ’90s though, you might think that it would be an experience that would have passed you by. Eastern Europeans for instance didn’t officially meet Mario for years.

Fortunately for them there was an industry of Chinese and Taiwanese clone makers whose products were readily available in those markets. For the countries without official Nintendo products it is these consoles and their brand names that have achieved cult gaming status rather than the real thing.

In Poland, [phanick] wanted to recreate his youth by building his own clone console (Polish Language, English translation via Google Translate). His chosen target was the Pegasus, the Taiwanese NES clone that was the must-have console for early ’90s Poles.

But he wasn’t just satisfied with building a Pegasus clone. Along the way the project expanded to include support for 72-pin NES cartridges as well as the 60-pin Pegasus ones, and the ability to play both PAL and NTSC games. For this dual-system support he had to include both sets of processor and graphics chip variants, along with logic to switch between them. He goes into some detail on the tribulations of achieving this switch.

The result is a very impressive and well-executed piece of work. The PAL games have a letterbox effect with black bars at top and bottom of the screen, while the NTSC games have slightly washed-out colours. But if you were a gamer of the day you’ll see these as simply part of the genuine experience.

He’s posted a descriptive video which we’ve embedded below the break, but with non-English commentary. It is however still worth watching even without understanding the audio, for its view of the completed board and gameplay.

SNES EPROM Programmer With Arduino

October 23, 2016 by Bryan Cockfield 17 Comments

Most video game manufacturers aren’t too keen on homebrew games, or people trying to get more utility out of a video game system than it was designed to have. While some effort is made to keep people from slapping a modchip on an Xbox or from running an emulator for a Playstation, it’s almost completely impossible to stop some of the hardware hacking that is common on older cartridge-based games. The only limit is usually the cost of an EPROM programmer, but [Robson] has that covered now with his Arduino-based SNES EPROM programmer.

Normally this type of hack involves finding any cartridge for the SNES at the lowest possible value, burning an EPROM with the game that you really want, and then swapping the new programmed memory with the one in the worthless cartridge. Even though most programmers are pricey, it’s actually not that difficult to write bits to this type of memory. [Robson] runs us through all of the steps to get an Arduino set up to program these types of memory, and then puts it all together into a Super Nintendo where it looks exactly like the real thing.

If you don’t have an SNES lying around, it’s possible to perform a similar end-around on a Sega Genesis as well. And, if you’re more youthful than those of us that grew up in the 16-bit era, there’s a pretty decent homebrew community that has sprung up around the Nintendo DS and 3DS, too.

Thanks to [Rafael] for the tip!
