If you want to prevent DS from complaining about needing a C3 disc for docked worlds, then all that you need to do is open "machine.cfg" from your DS folder with a text editor and modify "Game Name" "Docking Station" to have anything besides "Docking Station". (e.g. "Game Name" "Docked" or "Game Name" "Exodus") Possible Problems: Please understand that by doing this, "gnam" will not report "Docking Station" and thus anything that depends on this may not work properly. Ron's House falls into this category.
