# Rogue Galaxy: a matching PlayStation 2 decompilation

> Rogue Galaxy reconstructs the NTSC-U PlayStation 2 game's main executable and five overlays as C or C++. Its build extracts remaining library code and data values from the user's disc, then compares all six linked images with the retail files; the author reports byte-identical outputs.
