- Integrated Lua 5.4 engine (32-bit mode for embedded ARM) - Created LuaGame wrapper class implementing Game interface - Added C++ bindings exposing renderer, game state, and input to Lua - Implemented SD card loader for automatic .lua game discovery - Updated GameLauncher to support std::function for lambda captures - Made Game class members public for Lua bindings access - Added example Lua games: counter, snake, bouncing ball - Included comprehensive API documentation Games can now be written as .lua text files on SD card and loaded without recompilation. Build size: 747KB UF2, Lua VM uses ~50-80KB RAM.
