N64 Controller Serial Protocol Sniffer

Here is a description of the Nintendo 64 controller protocol, with information I found during development. It includes pictures and capture files that will be very useful if you want to interface with a Nintendo 64 console or controller. I did not figure out the protocol from scratch, I used documentation from other people. Clan crest lineage 2 16x12.

Please check the references at the end of this page. The information here is enough to interface successfully with a Nintendo 64 console or controller, but not with peripherals like Rumble Pak and Memory Pak.

Interfacing with peripherals is more complicated since it requires implementation of new commands and on-the-fly CRC computing. If you need this kind of information, you will be able to find it in the references I mentioned. Electrical specifications: N64 connector pins: VCC is 3.3V.

I don't know the max current this port can provide. DATA is a bidirectional line, connected using a common collector configuration. It means that instead of using 0V and 3.3V for low and high logic level, it uses a 0V and high impedance, so you will need to include a pull-up resistor to be able to read the line.

If you are using a microcontroller, there is a chance you have some I/O pins with built-in pull-up already. Protocol • Line is kept in level high when idle. • Each bit can be detected by a falling edge, and has exactly 4us.

A zero consists in line low for 3us, and high for 1us. A one consists in line low for 1us, and high for 3us.

• Additionally to the usual bits, there are two special stop bits. 'Console stop bit' is line low for 1us, and high for 2us (3us total). 'Controller stop bit' is line low for 2us, and high afterwards (last bit). • When transmitting a byte, most significant bits go first. • A communication frame always starts with the console sending a 1 byte long command. • The basics commands needed for interfacing with the controller or console are the commands 0x00 and 0x01. There is also commands 0x02 and 0x03, but they are related with controller paks reading (not described in this document).
