# Champions: Return to Arms: PS2 code research and native recompilation

> Champions: Return to Arms research maps the US PS2 game's executable, symbols, level scripts, file formats and online behavior. Its tools disassemble and compare original functions, then translate a player-supplied executable to C++ for a native runtime and Godot host; the author maintains an address-based findings ledger.
