Random gaming things:

Your monkey in Super Monkey Ball 2 is supposed to make a different sound than normal when passing through a warp goal, but due to a bug, this only happens during the replay.

It turns out that the variable for "how many stages you're advancing" is only updated after the sound effect plays. This is how it's supposed to sound: https://is.a.qute.dog/media/ELzQgBpMj2UemjI-gvY
