- Created emulator-specific lua_game_emulator.cpp using filesystem instead of FatFS - Created lua_game_loader_emulator.cpp to scan games/lua_examples directory - Updated CMakeLists.txt to include Lua 5.4 engine and bindings - Updated to SFML 3.0 API compatibility (event handling, sprite initialization) - Updated Game class to use public members for Lua bindings - Updated GameLauncher to use std::function for lambda captures - Added continuous 60 FPS rendering for smooth display - Emulator now loads and runs all three example Lua games
