A KallistiOS port to GameCube is underway, led by darc.
This page exists to serve as a general reference for KallistiOS GameCube related information until a better page can be created.
Wii support is planned as well, but GameCube is the current priority. Wii U support is not planned at this time, as it would likely require significant core KallistiOS changes.
Purpose/Goals
- Born as a personal side project by darc to play with a non-Dreamcast embedded target and to learn more about low-level hardware programming, kernel programming, and KallistiOS low-level internals
- Restore KallistiOS to a multi-arch project. KallistiOS 1.x was originally multi-arch (dc/ps2/gba) before all non-Dreamcast targets were removed with the KallistiOS 2.x release due to lack of progress and interest. GameCube/Wii pairs well with the Dreamcast. The additional targets help keep the kernel architecture robust and provide more testing capabilities.
- Facilitate cross-platform homebrew games and allow easier development of GameCube/Wii ports of Dreamcast homebrew. While console-specific code will still be required, a unified KallistiOS core will reduce porting burden, and higher level, platform-independent KallistiOS APIs can be created for many components. OpenGL or SDL implementations can ease porting burden as well. This can help expand both the Dreamcast and GameCube/Wii homebrew dev scenes.
- For those concerned about the legality of libogc, KallistiOS serves as an alternative, as it does not use devkitPro/libogc.
Status
- Toolchain builder: Currently in PR (thanks pcercuei)
- Changes needed to general KOS: few left, currently pending (thanks quzar)
- GameCube arch: Not upstreamed yet (in progress by darc)
- Working: Most of core KOS kernel (interrupts/threads/etc.), USB Gecko for debug output, basic pad reading, external framebuffer for video output
- Upstreaming of core arch code expected soon(TM)
News
- Announcement 4/28/2025
- Doom port demonstration 6/21/2025
Running homebrew
Most accessible methods for running homebrew (non-exhaustive):
- FlippyDrive: ODE + real disc drive combo, solderless, USD$50+ kit
- CubeODE: Replaces disc drive with ODE via SD slot, solderless, about USD$50
- PicoBoot: Overrides BIOS with gekkoboot homebrew bootloader, easy soldering required, DIY and very cheap
- PicoLoader: Emulates a disc drive to boot a main homebrew app then re-enables real disc drive, solderless, DIY and very cheap
- XenoGC: Allows disc drive to boot homebrew from DVD-R, requires moderate soldering, cheap
- Action Replay: Requires rare Action Replay disc to load files from SD card reader
- Save exploits
