Knulli CFW is a fork of the open-source and completely free retro-gaming distribution batocera that can be copied to an SD card with the aim of improving many of the emulation handhelds on the market that usually ship with incomplete and often non GPL compliant software. It supports many emulators and game engines out of the box.

Platform-specific build configuration. This is where to include special patches/configuration files needed to have particular components work on a particular platform. It is instead encouraged to apply patches at the location of the package itself, but this may not always be possible.buildroot
Buildroot, the tool used to create the final compiled images. For newcomers, you can safely ignore this folder. Compilation instructions can be found on the wiki.configs
Build flags, which define what components will be built with your image depending on your chose architecture. If you're trying to port Batocera to a new architecture (device, platform, new bit mode, etc.) this is the file you'll need to edit. More information on the build configuration section on the buildroot compiling page.package
The "meat and potatoes" of Batocera. This is where the majority of emulator data, config generators, core packages, system utilities, etc. all go into. This is the friendliest place to start dev-work for new devs, as most of it is handled by Python and Makefile.scripts
Various miscellanous scripts that handle aspects external to Batocera, such as the report data sent to the compatibility page or info about the Bezel Project.A cheatsheet of notable files/folders can be found on the wiki.
