Case study

atolm: a matching decompilation of Panzer Dragoon Saga

atolm reconstructs selected Panzer Dragoon Saga program segments as C source and compares compiled bytes with originals extracted from the user's USA Disc 1. Its research identifies the Hitachi SHC compiler family and documents differences between the available Release31 compiler and the likely original build. The author reports byte-matched units while tracking attempted and unattempted code separately.
