# SuperMarioRPGSNESRecomp: an early 65816 static recompilation

> SuperMarioRPGSNESRecomp applies snesrecomp to Super Mario RPG: Legend of the Seven Stars, compiling qualified 65816 code paths to C while other paths run through an interpreter. The shared snesrecomp runner emulates the game's SA-1 coprocessor, and coverage tools collect dispatch misses to guide later regeneration. The author reports a working attract loop and early-game replay, with two qualified ahead-of-time variants.
