So I know now that it's possible to import music and custom graphics in the ROM. I haven't tried it yet, but by the time the project is almost done, I should be a pro at it.
I established a list of most the notable posters on r21freak and what kind of stages to give them. There are:
+8 people with SPECIAL stages
+4 proud owners of Switch Palaces
+4 Castle people
+2 Fortress people
The stamina players (TCP, Reen, and Monst3rjoe, etc.) will have their own "subworld" (kinda like Vanilla Dome, Valley of Bowser, etc.). Since it's pointless to have a subworld with only 3 levels, filler levels will be filled in with DF or other song references.
