This, some people have bad full isos from the start and compress them and of course they are bad compresses, or they have a good iso and compress them with gcisotool and break the alligment becuase that tool doesnt care about the alligment.
Gonna give an example if you google the Naruto: Gekitōu Ninja Taisen! 3(jap only game) your first choice on a famous website gives you a full iso, and yet this full iso is bad, it doesnt match redump and since naturo uses audiostreaming its out of alligment, and it will crash the first time it tryes to play the music, shutting down the console.
This is an example among manny, people should realy make sure their md5s match before anything else and never compress with GCISOTOOL, only with tools that are known to work with 32k alligment.
Doesn't Gamecube ISO Tool support 32k alignment now? It's right there in the options...just got to switch it from its 'default' 'auto' option to '32 KB'...or does GC ISO Tool not work properly in general? I like the interface much better...as well as the extra options. Just wondering.
