Nintendo Wields DMCA Ax On Fan Games

September 7, 2016 by Jenny List 61 Comments

In a move that may sadden many but should surprise nobody, Nintendo of America has issued a DMCA takedown notice for 562 fan-created games created in homage to Nintendo originals and hosted on the popular Game Jolt site. Games affected include Mario, Zelda, and Pokémon based creations among others, and Game Jolt have responded, as they are required to, by locking the pages of the games in question. They state that they believe their users and developers should have the right to know what content has been removed from their site and why the action has been taken, so they have begun posting any notices they receive in their GitHub repository.

It is likely that this action won’t be appreciated within our community, however it’s important to note that while there are numerous examples of DMCA abuse this is not one of them. Nintendo are completely within their rights over the matter, if you use any of the copyrighted Nintendo properties outside the safe harbor of fair use then you will put yourself legitimately in their sights.

Something that is difficult to escape though is a feeling that DMCA takedowns on fan-created games are rather a low-hanging fruit. An easy way for corporate legal executives to be seen to be doing something by their bosses, though against a relatively defenseless target and without really tackling the problem.

To illustrate this, take a walk through a shopping mall, motorway service station, or street market almost anywhere in the world, and it’s very likely that you will pass significant numbers of counterfeit toys and games copying major franchises including those of Nintendo. A lot of these dollar store and vending machine specials are so hilariously awful that their fakeness must be obvious to even the most out-of-touch purchaser, but their ready availability speaks volumes. Unlike the fan-created games which are free, people are buying these toys in huge numbers with money that never reaches Nintendo, and also unlike the fan-created games there’s not a Nintendo lawyer in sight. Corporate end-of-year bonuses are delivered on the numbers of violations dealt with, and those come easiest by piling up the simple cases rather than chasing the difficult ones that are costing the company real sales.

We’ve covered many DMCA stories over the years, and some of them have been pretty shocking. Questions over its use in the Volkswagen emissions scandal, or keeping John Deere tractor servicing in the hands of dealers. Let’s hope that the EFF and Bunnie Huang’s efforts pay off and dismantle section 1201, one of the most nonsensical parts of the law.

NES Light Gun Fires Awesome Laser Effect

August 31, 2016 by Gerrit Coetzee 26 Comments

[Seb Lee-Delisle]’s NES lightgun gave us pause as the effect is so cool we couldn’t quite figure out how he was doing it at first. When he pulls the trigger there erupts the beam of light Sci Fi has trained us to expect, then it explodes in a precision sunburst of laserlight at the other end as smoke gently trails from the end of the barrel. This is a masterpiece of hardware and trickery.

The gun itself is a gutted Nintendo accessory. It looks like gun’s added bits consist of two LED strips, a laser module (cleverly centered with two round heatsinks), a vape module from an e-cigarette, a tiny blower, and a Teensy. When he pulls the trigger a cascade happens: green light runs down the side using the LEDs and the vape module forms a cloud of smoke in a burst pushed by the motor. Finally the laser fires as the LEDs finish their travel, creating the illusion.

More impressively, a camera, computer, and 4W Laser are waiting and watching. When they see the gun fire they estimate its position and angle. Then they draw a laser sunburst on the wall where the laser hits. Very cool! [Seb] is well known for doing incredible things with high-powered lasers. He gave a fantastic talk on his work during the Hackaday Belgrade conference in April. Check that out after the break.

So what does he have planned for this laser zapper? Laser Duck Hunt anyone? He has a show in a month called Hacked On Classics where this build will be featured as part of the Brighton Digital Festival.

Tricking Duck Hunt To See A Modern LCD TV As CRT

August 30, 2016 by Jenny List 47 Comments

A must-have peripheral for games consoles of the 1980s and 1990s was the light gun. A lens and photo cell mounted in a gun-like plastic case, the console could calculate where on the screen it was pointing when its trigger was pressed by flashing the screen white and sensing the timing at which the on-screen flying spot triggered the photo cell.

Unfortunately light gun games hail from the era of CRT TVs, they do not work with modern LCDs as my colleague [Will Sweatman] eloquently illustrated late last year. Whereas a CRT displayed the dot on its screen in perfect synchronization with the console output, an LCD captures a whole frame, processes it and displays it in one go. All timing is lost, and the console can no longer sense position.

[Charlie] has attacked this problem with some more recent technology and a bit of lateral thinking, and has successfully brought light gun games back to life. He senses where the gun is pointing using a Wiimote with its sensor bar on top of the TV through a Raspberry Pi, and feeds the positional information to an Arduino. He then takes the video signal from the console and strips out its sync pulses which also go to the Arduino. Knowing both position and timing, the Arduino can then flash a white LED stuck to the end of the light gun barrel at the exact moment that part of the CRT would have been lit up, and as far as the game is concerned it has received the input it is expecting.

He explains the timing problem and his solution in the video below the break. He then shows us gameplay on a wide variety of consoles from the era using the device. More information and his code can be found on his GitHub repository.

Open Source SNES To USB Converter Lets You Emulate Legally

August 28, 2016 by Gerrit Coetzee 59 Comments

[Andrew Milkovich] was inspired build his own Super Nintendo cartridge reader based on a device we covered an eternity (in internet years) ago. The device mounts a real cartridge as a USB mass storage device, allowing you to play your games using an emulator directly from the cart.

This uses a Teensy++ 2.0 at its core. [Andrew] had to desolder the EEPROM pins from the SNES cartridge and reverse engineer the pinouts himself, but the end result was a device that could successfully read the cartridge without erasing it, no small accomplishment. The finished cartridge reader is build on some protoboard and we’d like to complement [Andrew] on his jumper routing on the underside of that board.

Of course, the experience of any console is just not the same without the original controller. So [Andrew] went a step further and made his own SNES controller to USB converter. This had the venerable Atmel ATmega328 at its core, and can be used separate from the cartridge reader if desired.

HoloLens NES Emulator For Augmented Retro Gaming

August 24, 2016 by Moritz Walter 5 Comments

[Andrew Peterson] was looking for a way to indulge in his retro gaming passions in a more contemporary manner. His 3D NES emulator “N3S” for Windows brings Nintendo classics to the HoloLens, turning pixels into voxels, and Super Mario into an augmented reality gingerbread man.

To run NES games on the HoloLens, [Andrew’s] emulator uses the Nestopia libretro core. Since AR glasses cry for an augmentation of the game itself, the N3S re-emulates the NES’ picture processing unit (PPU), allowing it to interpret a Nintendo game’s graphics in a 3D space. [Andrew] also put together a comprehensive explanation of how the original Nintendo PPU works, and how he re-implemented it for the HoloLens.

The current version of the N3S PPU emulator automatically generates voxels by simply extruding the original pattern data from the game’s ROM, but [Andrew] is thinking about more features. Users could sculpt their own 3D versions of the original graphic elements in an inbuilt editor, and model sets could then be made available in an online database. From there, players would just download 3D mods for their favorite games and play them on the HoloLens.

According to [Andrew], the emulator reaches the limits of what the current pre-production version of the HoloLens can render fluently, so the future of this project may depend on future hardware generations. Nevertheless, the HoloLens screen capture [Andrew] recorded makes us crave for more augmented retro gaming. Enjoy the video!

Pokémon Center Charging Station

August 20, 2016 by Jenny List 18 Comments

If you watch Pokémon Go enthusiasts, you may have noticed something of a community spirit among gamers congregating at busy in-game locations. [Spencer Kern] wanted to encourage this, so produced what he describes as a water cooler for Pokémon Go players, a Pokémon-styled charging station with multiple USB ports.

His build centres on a Yeti 400 solar power pack and a large multi-port USB hub, for which he has built a detailed wooden housing in the style of a Pokémon Center from the earlier Nintendo games. The idea is that gamers will congregate and plug in their phones to charge, thus bringing together a real-world social aspect to the game. We can see the attraction to gamers, however we suspect most Hackaday readers would join us in not trusting a strange USB socket and using only a USB cable not equipped with data conductors.

Still, the housing has seen some careful design and attention to detail in its construction. He started with a 3D CAD model from which he created a set of 2D templates to print on paper and from which to cut the wood. As many of his dimensions as possible were taken from common wood stock to save machining time, and the structure was assembled using wood glue before being sanded and filled. Finally, the intricate parts such as the Pokémon logo were 3D printed, and spray painted. The result is a pretty good real-world replica of the Pokémon Center that you’d recognise if you were a player of the original games, and he reports it was a hit with gamers in his local park.

We’ve covered quite a few Pokémon Go hacks recently, but many of them have had a less physical and more virtual basis. We did see a real-world Pokémon-catching Pokéball though, and of course there was also the automated Pokémon egg incubator.

Thanks [Genki] for the tip.

Creating Unbeatable Videogame AI

August 16, 2016 by Brian Benchoff 21 Comments

Super Smash Bros. Melee is a multiplayer fighting game released for the Nintendo GameCube in 2001. For the last decade and a half, it has become one of the premier fighting game eSports, and it is the reason Nintendo still makes a GameCube controller for the Wii U. Smash Melee has an intense following, and for years the idea of an AI that could beat top-tier players at Melee was inconceivable – the game was just far too complex, the strategies too demanding, and the tactics too hard.

[Dan] a.k.a. [AltF4] wasn’t satisfied that a computer couldn’t beat players at Melee, and a few years ago started work on the first Melee AI that could beat any human player. He just released Smashbot at this year’s DEF CON, and while the AI is limited, no human can beat this AI.
