DIY NES controller makes no changes to the design

diy-nes-controller

We like this project for its sheer simplicity. After all, recreating the hardware in the controller for a modern gaming system is next to impossible. [Guillermo A. Amaral B.] had a bunch of parts sitting around and decided to try his hand at recreating an original Nintendo Entertainment System controller. If you're not familiar with the electronics inside this brand of retro gaming hardware … [Read more...]

Stuffing an NES into an FPGA

megaman_fpga

When the developer of the µTorrent torrent client and the ScummVM  LucasArts adventure game interpreter gets bored, something cool is bound to happen. Luckily for us, [Ludde] was a bit listless over Christmas, and with more time than energy to burn, implemented a Nintendo Entertainment System on an FPGA dev board. The NES was powered by a Ricoh 2A03 CPU, a chip nearly identical to the 6502 … [Read more...]

Dead NES controller used as a Makey Makey shield

makey-makey-nes-controller

[Guillermo Amaral's] NES controller was in great shape. Well, except for the fact that it didn't work. Upon closer inspection it seems the shift register -- which is the only IC on these ancient peripherals -- had given up the ghost. But he made it usable again by making the NES controller into a MaKey MaKey shield. You should remember the MaKey MaKey. It's a little board that lets you create … [Read more...]

The smallest NES controller ever

NES

A few months ago, [Ben] saw a video of the world's largest NES controller. "I bet I could make the smallest," he thought in a strange game of one-upmanship. Now [Ben] has the smallest fully functional NES compatible controller, a feat of engineering that can only end in very, very sore thumbs. The old NES controller is a very simple device: eight buttons are connected directly to a 4021 … [Read more...]

Emulators 101: how to write a program that functions like an NES CPU

how-to-write-an-NES-emulator

We'd bet everyone reading this article has played a game on an emulator at some time or another. And you may have a base idea of how those emulators work. But we'd wager the vast majority of you are clueless about the actual implementation of game emulators (we know we are). But that has all changed after seeing this demonstration of how [Bisqwit] wrote his own NES emulator. The description … [Read more...]

Adding Famicom audio channles to an NES without messing up the console

CastlevaniaIIImod

[Callan Brown] wrote in to show us a really interesting NES audio hack. [Callen] decided that he wanted the full Castlevania III audio experience, which (without modifications) can only be had through the original Japanese Famicom console. [Callen] weighed a few adapter options, and instead decided to come up with his own. The issue is that the Japanese Famicom and the American NES actually … [Read more...]

NES light gun gets a burning laser upgrade

burning-laser-nes-zapper

The Nintendo Light Gun makes a perfect burning laser. Of course it's been gutted to make this happen. Nonetheless, the retro look can't be beat, and the gun form factor is just what you need in a laser weapon. This will literally burn your eye out of your head, so [Justin] and his buddies over a North Street Labs are all wearing protective goggles designed for this laser's wavelength. But they … [Read more...]
