Question about Yaz0 decompression...

**ShizZy** · April 21st, 2005, 01:12

My main question - are multiple files compressed within a single szs/rel file? I wrote up a decompressor for practice, and it's doing something right, but obviouselly not everything - for it's spitting out wrong data. I'll attach the source. Help appreciated.

btw... Can't just copy thakis', that'd be cheating

Nevermind, think I got it...

I'm looking forward to what you are writing :-) szs files contain multiple files (as do .arc files), but rel files are quite uninteresting (they are exectuable files).

thakis, your rarcdumper seems to crash when ever I try to use it. (dragging a rarc file ontop of the icon). the rarc was decompressed from a wind waker rel file, (with my decompressor), but I compared the bytes and it exports exactly the same as yours.

Okay, I followed the directions, and did it via the dos prompt. Same deal. Is it something to do with the REL files? Do I have to do some mods to get it to work with them as well? Have you tried it with Wind Waker?

As mentioned above: .rel files are yaz0-compressed ".exe" files. They cannot be read by rarcdump. deyaz0 a szs file (mario) or take a look at the .arc files that are shipwith zelda: if they start with "Yaz0", decompress them and give the uncompressed file to rarcdump, if they start with "RARC", you can give them to rarcdump immediately.
