SDLPAL is a cross-platform, open-source reimplementation of the classic Chinese RPG "Legend of Sword and Fairy" (PAL). The engine loads original game data (provided separately by the user) and reproduces the full game experience including battle systems, map exploration, menu interactions, script-driven events, and cutscenes. It is built as a monolithic C/C++ application using SDL for input, video, and audio, with optional OpenGL rendering and GLSL shader support. The codebase includes a comprehensive platform abstraction layer supporting Windows (desktop and UWP), Linux, macOS, Android, iOS, 3DS, Wii, Emscripten (web), and libretro. Audio is handled through a modular player interface that can use native MIDI, software synthesis (TiMidity, OPL emulation via MAME/DOSBox/Nuked cores), or compressed codecs (MP3 via libmad, Ogg Vorbis, Opus). The project is actively maintained, with recent commits and multiple CI workflows. While the core game logic is tightly coupled to PAL's data formats, many individual subsystems (configuration, audio players, OPL emulation wrappers, binary I/O, resamplers, font loaders, and decompression routines) are cleanly abstracted and could be reused in other projects with minimal adaptation.
