[Larsim] worked out the timing necessary to read button and joystick data from an N64 controller using an ATtiny85 microcontroller. The project was spawned when he found this pair of controllers in the dumpster. We often intercept great stuff bound for the landfill, especially on Hippie Christmas when all the student switch apartments at the same time.
Instead of cracking the controllers open and patching directly to the buttons, [Larsim] looked up the pinout of the connector and patched into the serial data wire. In true hacker fashion, he used two 5V linear regulators and a diode in series to step his voltage source down to close to 3.6V, as he didn’t have a variable regulator on hand. It does sound like this causes noise which can result if false readings, but that can be fixed with the next parts order.
The controller waits for a polling signal before echoing back a response in which button data is embedded. This process is extremely quick, and without a crystal on hand, the chip needs to be configured to use its internal PLL to ramp the R/C oscillator up to 16Mhz. With the chip now running fast enough, an external interrupt reads the serial response from the controller, and the code reacts based on that input.
It seems the biggest reason these N64 controllers hit the trash can is because the analog joystick wears out. If you’ve got mad skills you can replace it with a different type.
Although Hack A Day is no stranger to console conversions, this portable N64 build is worthy of note. The article itself is in Spanish, but for those that don’t speak the language, the steps and components necessary are well documented in pictures. There’s even a video of the finished product after the break.
What is especially interesting about this project is the professional looking build quality of the finished product. One might think it’s a custom injection molding job or possibly 3D printed, but everything is done with only glue, filler, and paint. A controller and console is hacked up to provide the raw materials for this build. An expansion pack is even attached to this console for good measure.
Power is provided by a 6800mA battery, and the console features a generous 7 inch display. A good wiring schematic is also provided in this article, so maybe it will inspire other quality console hacking in the future. Continue reading “A Professional Looking N64 Portable Build”
[David] recently wrote us to share the portable Nintendo 64 he constructed with the help of the friendly people over at the ModdedbyBacteria forums. We are no strangers to N64 portables, as you may have noticed, but this one was just too good to pass up.
Sheathed in a metallic blue case, this console is an instant standout among the other portable N64 mods we have seen. As you would expect, he trimmed down an N64 console board and some various controller bits in order to fit them into the case, finishing it off with a 5″ PSOne display panel. A small fan protrudes out of the back side of the device, which seemed out of place at first. However, it not only keeps the console cool, but it can serve as a bit of a “kickstand” as well, if the console is placed on a flat surface. [David] also added a dongle for the bottom of the console, which allows him to use an external N64 controller if he so desires.
To be honest, one of our favorite features is that the game cartridges do not stick up from the back of the case when inserted. He included just enough room to allow the game to be completely hidden while playing. Nice job!

As gaming consoles age the controllers will inevitably show some wear, and sadly may give out all together. [Kyle] couldn’t bear to watch his Nintendo 64 controller bite the dust so he replaced the thumb stick with one from a PlayStation. This is a bigger job than you might imagine because the two parts are fundamentally different. The original N64 stick uses a rotary encoder to output data to the control chip, while the PlayStation stick is an analog device. [Kyle’s] solution was to read the analog values using a PIC, but lower in the thread you can read about another user who pulled off a similar hack using an AVR. Both convert the signals into the rotary encoder format that the N64 chip is listening for. From the looks of the clip embedded after the break, this couldn’t work any better!

Like many people [Kyle] loves the Nintendo 64 and decided he wanted a portable version of his beloved console so he could play games while on the move. One year, two PSOne screens, and three N64 consoles later, his vision is complete. A Game Boy Advance travel case was gutted and used to house the console, hence the “N64 Advance” moniker. Like many others, his project uses a PSOne screen for the display, and a Li-Poly battery pack that provides up to 3.5 hours of playing time. He made sure to include other members of the Nintendo family in his build by adding a pair DS Lite speakers to the mix.
This build also includes some nice “extras” such as having the N64 RAM expansion pack built-in, headphone and A/V out ports (with a screen kill-switch for TV use), and an external controller port that can be used by either the first or second player. Be sure to check out the video of his build after the jump.

Are you hardcore enough to build your own 32-bit ARM powered gaming console AND use point-to-point soldering to accomplish this? [Craig Bishop] did just that when building his GameSphere console project. First thing’s first, click through the jump and watch the game play video. He wrote that game in the C language in less than a day which in itself is quite remarkable. On the hardware side of things he’s got an interesting mix; an Ateml AT91R40008 chip drives this system with PIC 18F4682 for VGA signal generation and a PIC 18F2685 to interface with the N64 controller. We like what he’s done so far and would love to see this end up in its own game cabinet. Continue reading “32-bit ARM7 gaming rig”
We love a beautiful and successful N64 portable mod, (In case that fact wasn’t already obvious). And today we would like to add [cndowning’s] Nimbus N64 to our list of favorites.
The base is made from vacuum formed plastic while the buttons come from a modified superpad and the screen is a Zenith 5inch. We couldn’t find word on battery life or weight, but for those that like a hunt, or have other questions, the build logs are available. Follow the jump for a video of the Nimbus in action.
