Well i've got REALbasic for the macintosh (www.realbasic.com) and i can compile for windows (demo mode only for me since i've got the standard version and dont wanna upgrade to pro ($300 -> Aust $600 )). I've also got zlib and the docs and sources on how to use it in REALbasic. So ill see what i can come up with

If i do ever manage to uncompress/deflate the format ill create a prog and release the step for doing it

Cheers,
Matrix
