Sorry for not responding earlier, but I did delete Roy's result screen portraits, and...
It still freezes! Ugh.
Maybe it has something to do with the Result Screen itself (it's the Peach's Castle one from Mewtwo2000), but I wouldn't think that would be whats causing the freezing since it only affects Ike. Plus I wouldn't know where to look in the STGRESULT.pac .
This exact thing happens on mine too...I have a custom stage result screen but that's it. But it only seems to be Ike that freezes and only if the game is left on the results screen for a certain amount of time.
Hmm... that's strange. Mine doesn't freeze after a few minutes, it freezes for me right after a match. It doesn't even show a black screen or anything, it freezes after the announcer says "Game Set!", and the pauses. Sometimes it makes that beep, sometimes it doesn't.
