Arduino USB Host Controller Driver
The source code for the Xbox 360 USB driver is available on my github here https://github.com/Ryzee119/n360/tree/master/n360_USB_driver
Custom N64 ROM
To assist in development on my n360 PCB design I wrote a custom Nintendo 64 ROM that reports all the button presses, analog stick outputs, what peripheral the console thinks is installed, some basic Controller Pak read/write checks and the ability to toggle the Rumblepak.
This will only work on real Nintendo 64 hardware or cycle accurate Nintendo 64 emulators (Such as cen64). To get this on real hardware you will require a flash cart (Such as an Everdrive64).
One generous and inventive user has developed a 3D printable mount that allows the Xbox 360 wireless Receiver’s bare circuit board to be mounted internally. He even has mounted a button and LED indicator on the front of his Nintendo 64!, alternatively the sync button could easily be accessed through a hole in the top shell instead of routing wires to the front of the console. He has kindly offered the 3D files for anyone to download: Receiver Holder.zip (Thank you Rich)
