Despite the fact that art.dat was 9MB, only 3MB of resources were extracted.
This is where .eco files come in.
.eco files are Encrypto! files, a propitary encrypter used by the people who made the game (Retro64)
How do I know this? Because Water Bugs had the encrypto.exe file inside it's animations folder.
By experimenting with it, Encrypto! converts .XML files into .eco files, which allow the game to load data in the encrypted art.dat file. The best part is that there are not only encrypted and decrypted versions of waterlevel1.XML but a batch file actually gives the encryption key for decrypting it!

We're *this* close to decoding Water/Cosmic Bugs.
I know it has been several years, but it would be of great value and interest to me to know more about Encrypto! and the possibility of DECRYPTING .eco files given a game's encryption key.
I am currently modding Spongebob Squarepants: Obstacle Odyssey, made also by Retro64 and it also uses .eco files. It would be very helpful to me to be able to turn those .eco files back into XML.
