About

A VR port of SpaghettiKart, the native PC port of Mario Kart 64. The game is not emulated and not shown on a virtual screen: the renderer draws every frame twice, once per eye, so the karts, tracks and item boxes have real depth around you.

Head tracking is applied to the game's own chase camera, so you can look around while the game keeps driving its line. The HUD, the lap times and the menus sit on a panel that stays fixed in the room instead of following your head.

Features

True per-eye stereo 3D with head tracking, rendered at the headset's full resolution
HUD, minimap and menus on a panel fixed in the room, with adjustable distance and size
Sky drawn as a dome around the camera, so it stays put when you look around
Objects and track pieces stay visible when you turn your head away from the driving line
Motion controllers mapped to the N64 pad, remappable in SpaghettiKart's controller menu
Adjustable world scale, HUD width and render resolution

Manual

Installation

Generate mk64.o2r and spaghetti.o2r from your ROM with SpaghettiKart on a PC: put the ROM in the source folder as baserom.us.z64 and build the ExtractAssets target.
Enable developer mode on your headset.
Download the APK below and sideload it with SideQuest or adb install -r SpaghettiKart-VR-0.2.0-beta1.apk. SideQuest is a Quest tool, so on PICO use adb or whichever sideloader you already use.
Copy the game data onto the headset: adb push mk64.o2r spaghetti.o2r /sdcard/Android/data/dev.spaghettikart.vr/files/
Launch it from Library → Unknown Sources on Quest, or from your library on PICO.

Good to know

This is the first beta. Tested on Quest 3; the PICO build is untested, so please open an issue on GitHub if it does not start or the controllers do nothing.
PICO needs PICO OS 5.9.0 or newer: only from that version does the PICO runtime work with the generic Khronos OpenXR loader the port uses.
Split-screen multiplayer is disabled in VR, so only single player can be selected.
The VR settings (world scale, HUD width, panel distance, render resolution) are in spaghettify.cfg.json on the headset; there is no in-headset settings menu yet.

Controller mapping

N64	Touch
Control stick	Left stick
A (accelerate)	Right trigger or A
B (brake)	B
R (hop, drift)	Right grip
Z (item)	Left trigger
L	Left grip
C-down / C-left	X / Y
C-up / C-right	Right stick up / right
Start (pause)	Left menu button

Hold the Meta button (PICO: the PICO button) to recenter the view and the menu panel. Everything is remappable in SpaghettiKart's controller menu, and Bluetooth gamepads work too.

Download

Install from your browser

Over USB, for Meta Quest and PICO: installs the app and copies your own game files to the right place. No SideQuest, no adb. USB install works in Chrome or Edge on a PC, Mac or Android phone. No PC? Open this page in the Meta Quest Browser on your headset and install it right there.

The installer needs JavaScript. Use the manual download below.

First time? Before you start

Turn on developer mode. Quest: Meta Horizon app on your phone → Devices → your headset → Headset settings → Developer mode. PICO: Settings → General → About → tap Software version 7 times, then Settings → Developer → turn on USB debugging.
Connect the headset to this computer with a USB cable that carries data (not a charge-only cable).
Close SideQuest and Meta Quest Developer Hub. If you use adb, run adb kill-server first: only one program can talk to the headset at a time.
Windows: if the headset doesn't show up in the list, install the Meta Quest ADB driver.
After pressing Connect, put on the headset and allow USB debugging for this computer.
