It’s the JoyBus protocol, super bespoke, super simple! Used for N64, GameCube, and Game Boy Advance.

Check out my RED ModRetro Prototype M64 versus my PURPLE M64... Beautiful! Plus a little Star Fox gameplay straight from the M64! Which color out of the 4 will you pick?

LodgeNet N64 and GameCube controllers working on real Super Nintendo!! Straight wire! 🤯 Ends up that the recently dumped, mysterious SNES dev cart rom with a GameCube controller displayed on screen, is indeed a controller tester rom used to test LodgeNet controllers. I decompiled the rom and discovered that it was bit banging a custom controller protocol over the normal controller’s data and latch pins.

Xibalba 64 is finally here! I'm very happy with how the game turned out! It looks amazing with the M64 on the living room TV, but of course is fully compatible with the original N64.

Banjo-Kazooie, running natively on iOS and iPadOS for the first time. Banjo: Recompiled is the native Banjo-Kazooie port. It is built with N64: Recompiled and uses headers and some functions from banjo.decomp for patches and enhancements. I built BearBirdPad’s iOS/iPadOS layer: UIKit and Metal support, Files setup, touch controls, saves, and input. Not an emulator. No N64 hardware simulation. No streaming from a Mac. The iPad build in this video runs at 60fps, in widescreen, through Metal. iPhone runs fantastic, too. Full touch controls are customizable. Controller, keyboard, and mouse input work. I used Codex 5.6 Sol for the iOS integration. Source below.

The hotel LodgeNet N64 controller now working unmodified on real Nintendo 64 ‘home game system’ with joypadOS. Fully open source, runs on pi pico, inexpensive parts, hot-swappable between SNES, N64 and GameCube LodgeNet controller variants. Convert to USB or native N64/GC console output. Were there millions of these in the wild? Who has one?
