I worked on new torps awhile ago and skwasjer told me the torpedo types were hardcoded (I had made new nodes with the mk 28,31 and 35 in the . dat and all the corresponding ids and stuff .sim .zon) in the game and while it is possible to transform existing types you can't add new types, at least the types appearing in the .sim are allways the same : hard coded list in sh4
