It is NOT the screenpack that's the problem. It's fvcking Mugen. Even with the normal screenpack I get this problem, and that problem is it randomly shuts down sometimes when playing Team Arcade, and only 70-80% of the time my mp3s play.
And I even downloaded a new fvcking mugen and it's still acting up like a b!tch. The only thing I kept of course are the character, sound and stages folders because that's all the data I really needed to transfer, plus the folder of my one other screenpack which I stopped using to see if the problem still persisted, and it did. Fvck (MC style).
It can't be my Mugen, though, since I downloaded another one and scrapped my old one. Could it be the character files...no they work perfectly. The stages...nah. Sound files are ok...nope, Mugen is just gay.
I mean, what is the cause of getting a "Mugen had to close, sorry for the inconvenience" message at random times?
