Anyway, I am deciding on what to put in the SSE stage slots for the P:M version. There are 5 Brawl- stages that aren't also in P:M. 1337m is already in my P:M pack, so I could add Yoshi's Island -, New Pork City -, Frozen Pokemon Stadium 2 and Lavaville. That still leaves 3 SSE stage slots, but maybe I could put in Summit, Rumble Falls (Brawl), and Hanenbow.
Thank you for all of your hard work libertyernie. I'm working on a custom build of my own that acts as a "classic expansion pack" for the characters (all Smash versions and other versions each character took in other games). I'm not sure if I'll have the time to complete it, but it's a fun project (people, feel free to steal this idea and share!).
I had a question concerning the stage limit that is forcing you to be selective. At this time is there no code that allows for even more stages than what the expansion pack already contains?
