I got my hands on a program (on the PS2 itself) that can read the HDD file system and copy the files to/from USB data storage. The PS2 modding/homebrew community finally has someone that cracked it. As such I have ripped all the directory structure, except a few files that wouldn't copy but aren't DAT files anyway, they're file system and application files. I am now providing it in the hopes that someone out there will have the ability and interest to decipher the data formats and make mods available like PC users have had for years.

These are the files as of the March 22nd 2010 version update. The application to transfer them between a PC and PS2 is also included, though you need means to run PS2 homebrew to use it.
If anyone can give the info or files to Japanese modding communities, all the better, as they have more PS2 users, and I bet there's at least one OCD enough to put a dent in it.
