there are 2 different formats for the LZ77 ive seen used for the wii stuff. the first byte is either 0x10 or 0x11. IIRC, banners and stuff are the 0x10 type with a 4 byte magic word added to the beginning.
you can find code to compress banners ( ie the 0x10 format ) in many different banner tools. smash bros brawl uses the 0x11 format when it compresses snapshots/replays/levels to save on the SD card. you can find in the source code for smash stack the code which i wrote based on some c# code i found online to compress data in this format. my code is c++ using the Qt framework, and here is the code which i based it off of http://code.google.com/p/puyotools/source/...on/onz.cs?r=111
