Flip-top GameCube Portable

March 14, 2010 by Mike Szczys 27 Comments

Here’s another home console made into a portable. [Techknott] built this shiny GameCube handheld. You may remember him from his work on a portable Dreamcast and the wireless Xbox 360 interface. This time around he’s mirrored the finish; a good idea in concept but even his demo images are already plagued by smudges. But if you can keep your digits on the plastic buttons this makes for an eye-catching design. One part that we love is the flip-top screen that hides the optical drive. This is a much better solution than the exposed lens we saw on [Hailrazer’s] GC portable. As always, video after the break.

Arduino To Nintendo DS Interface

February 5, 2010 by Mike Szczys 15 Comments

[Hounjini] was poking around at the Game Boy Advanced bus of his Nintendo DS lite and figured out how to use it to connect an Arduino to the DS. For testing he’s soldered an IDC plug to the cartridge cover pin interface but this only requires four connections. The Arduino can both send and receive data from the DS lite as shown in the example videos after the break. The data access is made possible by making the Arduino look like a controller that the DS is happy to talk to.

Repair Or Improve Your NES

January 26, 2010 by Mike Szczys 20 Comments

There’s a warm place in our hearts for the original Nintendo Entertainment System. It’s too bad we don’t have that hardware sitting around anymore. But if you do there’s a chance it needs some TLC and there’s always room for a blue LED mod. [Raph] has a wonderful collection of NES hardware repairs and hacks that you should take a look at. These include replacing the power supply, fixing the cartridge connector, monkeying with the CIC chip, adding a reset button on the controller, converting the audio from mono to stereo, and yes, swapping in a blue LED. Oh, and as a side note, [Raph] gets a bit of extra hacker ‘cred for including “coded manually using VIM” at the bottom of his page. Classic.

Gorgeous Portable N64 Built To Order

January 25, 2010 by Mike Szczys 59 Comments

[Hailrazer] is at it again with a new portable N64 build. He’s done the impossible by improving upon his last design. The LCD screen is now mounted flush for a cleaner and smaller case. The controls draw from a lot of different sources; a gamecube stick for durability, a 3rd party N64 controller for buttons, and a PlayStation controller for the shoulder buttons that serve as L, R, and Z (either hand). There is a breakout box that allows two controllers to be plugged in. Combine this with the TV out feature and it acts as a console or a handheld. His in depth demonstration is embedded after the break.

The build log (linked above) details every part of the hack so that you can try to do this yourself. The relocation of the expansion slot requires patience and solid soldering skills. The case work is an art in itself. We speculate that this commission comes somewhere close to $1000 but it’s hard to put a price on quality craftsmanship. We’ve seen smaller, but these features and finished look can’t be beat.

NES Console To Cartridge Security In Depth

January 20, 2010 by Mike Szczys 45 Comments

[Segher] has reverse engineered the hardware and command set for the NES CIC chips. These chips make up the security hardware that validates a cartridge to make sure it has been licensed by Nintendo. Only after authentication will the console’s CIC chip stop reseting the hardware at 1 Hz. The was no hardware information available for these chips (go figure) so [Segher] had to do some sleuthing with the tools at hand which include some rom dumps from the chip pairs. He was nice enough to share his findings with us. We’re betting they’re not of much use to you but we found it an interesting read.

NES RAM Replacement

January 4, 2010 by Devlin Thyne 24 Comments

[Spatula Tzar] Turned on her NES one day to find it no longer working. Off went the case and out came the oscilloscope. After probing around for a bit, she found that one of the RAM chips was very hot. She hot aired off the bad chip implementing an “Impenetrable Aluminum Heat Shield of Science” to protect the rest of the components. In the chip’s place she soldered a wide DIP socket for which the NES engineers had thoughtfully left a place. Then, using a 128Mbit SRAM SOIC, she soldered it to 0.100″ headers to fit in the socket. As the original chip was only 16Mbit, unused address lines are tied high or low. The console is now fully functional again. Also checkout the comments on Oldschool NES ‘repair’ how-to.

[ZodTTD] has released a Nintendo 64 emulator for iPhone. It is available (for a price) at the Cydia store and can be installed on jailbroken iPhones. The video shows Wii Remote support as a control interface that uses both buttons and the accelerometer, an addition since we last looked at his work. There is no word about nunchuck functionality, a must if you’re going to try to 100% Mario64.
