Technical notes

Lutro is a Lua game framework for libretro implementing a subset of the LÖVE (Love2D) API. Runs .lutro/.lua games. Written for libretro, no standalone upstream.

retro_load_game() calls lutro_load(info->path) to load the game directory or archive (libretro.c:216). The core exposes love.filesystem.getAppdataDirectory to games as the system_dir (filesystem.c:296) but does not load any files from it itself. No BIOS, firmware, or system files required.

No BIOS or firmware files required. Generated on 2026-03-25T14:56:43Z
