This patch fixes the problem where the overworld music doesn't play after certain overworld levels. In fact, it allows you to choose for yourself which levels will disable the music and which will not. No freespace required normally.
Okay the sound issue is gone but now I'v got a couple of problems.
The Yoshi sprite is now GLOBALLY frozen and glitched and you doesn't walk after you've hit the Goal Tape. You'll just freeze in place.
Would not recommend this patch. It needs an Update!
