Created a single page PDF documenting the supported mappings.These are reported to be useful for Super Smash bros Melee and Brawl. Added 4 new button mappings, accessible by holding a C button for each mapping.Support for the Rumble Pack (since 1.5).Implemented new Gamecube commands for better compatibility, eg: GCLinux.Mostly useful to summon some emulator's menu while playing. eg: Sending L+R pressed with a NES controller, and sending CStick towards the right. Implemented button combinations which can affect how unaccessible Gamecube buttons and sticks are reported.Without this, in my opinion, NES games are almost unplayable with an SNES controller. NES mode can be forced on by holding the Start button at power-up.Added a feature to swap the NES A and B buttons.

Source code updates for modern avr-libc.Button combos used to simulate the C-Stick moving towards the right: Modified to send a movement to the left.NES/SNES controller polling frequency increased from 60Hz to 200Hz to reduce latency.Besides, the NES/SNESĪdd ATmega168 support (Build. Only support Gamecube accessory, implementing the adapter via the Not checked recently) in fact Gamecube based. NES/SNES (and other consoles) emulators on Wii are (or were, I have.At the time, I failed to find wiimote extension cables Gamecube connectors are too, but theyĬan be easily obtained from extension cables, which are cheap and easy But I did not take the time to very that because Means that they probably did not have low power consumption in mind NES and SNES controllers were designed to be wired controllers.Need to build a step-up switching voltage regulator. There is no 5 volts in the Wiimote connector. Q: Why did'nt you use the Wiimote accessory connector instead of doing a Gamecube adapter?Ī: I considered it, but I decided that using the Gamecube ports was better. The onlyĭifference is that we have to provide the 3.43 volts pullup resistor. The N64 version uses the same technique to control the controller's data line. I have a cheap wireless controller which drives the bus with 5 volts! Nothing seems Who knows if this could damage the console port? (In fact, Internal pullup or sending a 1 in output mode must not be done since this would Otherwise, I configure it as input-no_pullup.Ěctivating the I acheive this by playing with the Atmega8 pin direction. To 0, it just has to pull the signal to ground. When someone (gamecube or controller) wishes to set the signal On the gamecube side, the data signal is held at 3.43 volts via a pullup resistor If I had powered the MCU with only 3.3 volts, I would have had to useĪn ATmega8L which cannot run at clock rates above 8 mhz.Would have been necessary to use a voltage divider which would have required To preventĮxposing the microcontroller input to voltages higher than it's own, it

The data signal from the controller is at 5 volts when high.

I cannot know for sure what is the voltage threshold for a logic 1. (As I dont have the official controller specifications, It's better to use 5 volts for a logic 1 when driving the controller'sĬLock and Latch pins.

Snes and Nes controllers work at 5 volts.

The microcontroller is powered with 5 volts for three reasons: Here are a few example of what can be done with this circuit: Given the small size of this circuit, it's possible to fit it inside an original controller. Maybe it's a little overkill, but using thisĬhip allowed me to use my Multiuse tiny 1 PCB. Simple conversion circuit without using programmable components. Later, since a friend kept insisting that I should also design a N64 to Gamecube/Wiiīecause of the complexity of the Gamecube's controller protocol, it's not possible to build a I started by doing the NES and SNESĪdapter. Testing my code which I had prepared in advance. To continue enjoying the classics with proper controllers.Īs soon as I got access to a Wii (I still dont have mine), I started Update!: Since the Wii U and new Wii models are built without gamecube ports, I haveĬreated a new project that works via the Wiimote, making it possible Thinking about designing an Snes/Nes controllers to Gamecube adapter which would It would be possible to use Gamecube controllers to play those games, I started The Wii, is in my opinion one of their greatest ideas. Nintendo's idea of implementing support for NES, SNES and N64 games in their new console,
