Cores-spruce

Build bot for libretro cores targeting spruceOS handheld devices. Builds 32-bit (armhf) and 64-bit (arm64) cores using libretro-super.

Supported devices

Arch	Devices
arm64	Trimui Brick, Smart Pro, Smart Pro S, Miyoo Flip
armhf	Miyoo Mini/Mini+, Miyoo A30

How it works

• Two Docker images (cached on the toolchains release) provide cross-compilation environments
• Each core has its own GitHub Actions workflow — trigger individually or use Build All Cores to build everything in parallel
• Output: one zip per core containing cores/ (armhf), cores64/ (arm64), and a .info metadata file
• Built cores are uploaded to the beta-{branch} release

Usage

1. Build Docker images (only needed once, or after Dockerfile changes): run Build Docker Images
2. Build one core: run Build <corename> from Actions
3. Build all cores: run Build All Cores from Actions

TODO: cores not yet buildable

These cores are shipped by spruceOS but can't be built from libretro-super and need custom build processes:

• mkxp-z — hyphen in name breaks libretro-super's bash variable parsing
• mupen64plus — removed from libretro-super (replaced by mupen64plus_next)
• km_flycast_xtreme — KMFDManic/morpheuscast_xtreme fork uses bare as for ARM64 assembly, not cross-compile friendly
• km_ludicrousn64_2k22_xtreme_amped — KMFDManic fork has broken aarch64 dynarec source and missing includes
