The *1 tags files are not used at runtime by the player. The only reason they exist is for input when the player has to rebuild the binary database from scratch. The Hijack webserver also uses the *1 tags though, so it's a good idea to keep them around.

The *0 playlist files are just a series of 32-bit fids in binary form, in empeg byte order (little endian -- thanks Roger).

The database file format is just a catenation of most of the *1 tag fields for each fid, with separators etc.. easy to reverse engineer with a binary hex/ascii viewer/editor.

Cheers
