I heard you kids like meme stages.
All unused stages on the dlc page. Image varies on your /ui/replace/append/stage folder (I will not provide these yet because I'm lazy and I don't have any actually made, steal from the normal stage textures folder for missing ones that exist, and make your own I guess for others?). I will try to make a writeup about this someday (maybe this weekend since I don't really have plans). Special thanks to
@masterspike52 (I hope this tags correctly) for digging up the ancient documentation on adding characters to the dlc page and helping me with this.
edit: download
here put it in your smash folder
edit 2: Only Smash Run Running, Home Run, and Bomb crash the game. (ty
@Ordim3n for testing this)
