+[Skippable Cutscenes]
+author=Souzooka
+description=Press the START or X Button to skip cutscenes.
+// NOTE: This works by setting the cutscene length to 0, which is only checked every second or so.
+
+// Set up a call site to a code cave slightly above the cutscene length check
+// at this point in the code we know a cutscene is running,
+// and this code runs unconditonally every frame at that point
