Hi! I posted this question over on the PM forum but never got a response, so I figured I would try here.
I had tried to put
this Lucina texture meant for Marth over Roy. When I select Roy and choose a stage, it freezes on the loading screen. Other characters work fine. I checked the creator's website, and found the answer in the comment section. Apparently, I have to reduce the file size to 50% because Brawl can only load so much custom data.
Only issue is, I have no idea how to do this. If someone could give me directions on how, or point me to a tutorial, I'd be very appreciative.
