# TH11: byte-exact source reconstruction of Subterranean Animism

> TH11 reconstructs source for the original Japanese 1.00a executable of Touhou 11: Subterranean Animism. It records function boundaries and origins, compiles maintained C and C++ with a pinned VC9 toolchain, and compares complete generated code and relocations with the target.
