I found this This SSS has the PW expansion, all I have to do is change the icons and change the background image. The CUSTOM stages works again with this. I hope this helps you.

Hey does anyone know if this works with PW's stage expansion? Every time I try to add in my MiscData[80] with my custom icons and such, it freezes every time in Brawl before the SSS screen appears.
Does anyone knows why is this happen? Does anyone have this that works with PW's stage expansion?
If you don't mind sharing me that file please, I'd appreciate it, but I'd like to know why it won't work in the first place thought. Thanks!
