==Known Issues==
<!-- Mention any known issues relating to the game. Use the issue and PR template if necessary. If no notable issues are present, mention "There are no reported issues with this title." -->
===Freezes/softlocks===
The game is very unstable and will frequently crash within seconds even when using SPU LLVM & Accurate Xfloat Off.

===No audio===
When using anything other than SPU LLVM Recompiler and Accurate Xfloat OFF, the game will have no/some sound only.
