So, when I inserted custom music with AddmusicK for overworld, there seems to be no problem.
But when I press the P-switch, then this happens...
Weird thing is, when I restored my hack to previous state,(before I added another custom music.) this problem didn't happen at all.
Is because custom music have some problem or something...?
Anyway, can anyone help me, please?
Edit : I just solved the problem by import data to new file!
