Crash Fixes
Game (PlayStation Only)

- Introduced a temporary solution to prevent crashes caused by looping WAV files.
- If looping audio is added by a Creation, players may experience the looping audio once, but the game should no longer crash.

- Fixed an issue where SSF files were missing from the list of permitted file types when packing archives.
