you got any additional info on this you would like to share, like how to get the additonal characters to work i e neptune man, etc. any secrets, movies whatever. i mean there is very little offered atleast to people who only speak english that is.
I can answer your question about neptuneman. If you want to put in characters that aren't showing up in game, you need to replace a character you dont use or dont like with the character you want. To do this you need to copy the name of the character that you want to replace and paste that as the name of the character you want in the game. For example: If you don't Teapack man just copy his name(the player file in the folder) and paste it on Neptunemans file. Now teapack man will be replaced by neptuneman.
