Hacking Gamecube Image Archiving

[Kayot]

I've already asked here -> http://gbatemp.net/topic/326546-gamecube-image-archiving/

I figured I may as well ask here too since it's more relevant to DML than to an actual Gamecube.

Is there any effect beyond a smaller 7z regarding wiping the garbage bytes on a Gamecube iso? Would I be wiping audio tracks or anything like that?

It would make no data loss, but not all games work properly compressed, see the DML wiki for that.

Oh, I'm not compressing them via DiscEX. I'm using Gc-tool to wipe the garbage-bytes then compressing the iso with 7z. I'm mainly getting them ready for long term storage, much like my PS1 and GBA games. PS1 games had to turned into bin/cue or mds/mdf to preserve their audio tracks. I just want to make sure I'm not wiping audio tracks and what not. (I had to re-rip thirty or so PS1 games when I messed that one up.) The wiki isn't really clear on that one. It just says that streaming audio games can't be compressed. Hence why I'm a little worried about wiping the data since that may be the reason why. I don't plan to shrink the games if I decide to play them on the Wii.

I was mainly asking in case anyone has already tried it and found out the hard way.

It would make no data loss

I'll assume that means it won't wipe the audio tracks, right?

They is no loss as I said, audio tracks are still in it, you can do it as you want with the tool.

Okay, thank you. I just wanted to make sure since I get way better compression with that garbage data zero'd out.
