The sources of Petari (https://github.com/SMGCommunity/Petari), the Super Mario Galaxy decompilation by the SMGCommunity, at commit 0a5c6608dc3b4c44a9aa68c2535d1793dc565f02, unchanged but for LF line endings: LICENSE (as LICENSE-Petari.txt; CC0 1.0), include/, libs/ and src/. Left out: the game data Petari keeps from the original executable, the error message archive (include/Game/System/ ErrorArchive.hpp) and two tables (src/Game/System/GalaxyID.bcsv and StoryEvent.bcsv); GalaxyQuest's converter takes them from the player's own disc. The port's changes follow in the next commit, so `git diff petari-base -- decomp` shows them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
