Repo map
Leaf is split across several repositories in the Utility-Muffin-Research-Kitchen organization. Each is an independent repo with its own build.
| Repo | Role |
|---|---|
| Leaf | Release artifacts (SD install / recovery ZIPs) and cross-repo build orchestration |
| Jawaka | The launcher stack - jawakad daemon + launcher + menu + OSD |
| Catastrophe | Shared C UI toolkit the launcher and apps are built on |
| miniloong-launcher-switcher | The on-device mechanism that boots Leaf on top of stock - boot hook, session supervisor, install/recovery payloads, device defaults |
| mlp1-toolchain | The Buildroot-based Docker image used to cross-compile for the device |
| retroarch-builds | RetroArch fetch/build/packaging |
| Cores-spruce | libretro core builder, forked from spruceOS’s build lane (downstream of libretro-super) |
| leaf-contracts | Public schemas, fixtures, and normative contracts for third-party integrations |
| ScummVM-pak | Buildable reference content pak: adds the ScummVM system and its libretro core |
| leaf-n64-standalone | Standalone Mupen64Plus package for Nintendo 64 on MLP1 |
| Yabasanshiro-standalone | Optional standalone Saturn emulator package for MLP1, including corresponding-source publication |
| ssh-server | The SSH Server app (a .pak) |
| Thing-File | The file-manager app (a .pak) |
| Fugazi | The Fugazi live CRT-shader tuner app (a .pak) |
| CentralScrutinizer | Network file/ROM manager - a web UI served from the device (a bundled app) |
| miniloong-adb-keeper | SD payload used to enable developer access on the device |
| leaf-docs | This documentation site |
How they fit together
Section titled “How they fit together”- Leaf is the dispatcher: it calls each product repo’s own build/package targets and assembles the SD payload. You don’t build product repos individually to ship - you stage from Leaf.
- Jawaka depends on Catastrophe (header-only toolkit).
- retroarch-builds + Cores-spruce produce the RetroArch emulation stack that Leaf stages alongside the launcher.
- leaf-contracts defines the public content-pak interface; ScummVM-pak is the clean-checkout example an outside developer can clone and validate against it.
- leaf-n64-standalone produces the packaged standalone Nintendo 64 emulator that Leaf uses by default on MLP1.
- Yabasanshiro-standalone produces Leaf’s optional faster Saturn emulator; its public source-only release accompanies the runtime shipped by Leaf.
- miniloong-launcher-switcher owns everything device-stock-specific (the boot swap and install/recovery flow).
