I don't mean to clutter up the thread, but I've had 0 problems with winrar. Does everything I need it to. Other than it's own format, what would I need to use it for?
Its own format, and it handles everything else.
7zip files "CAN" compress amazingly well. Ive seen 700 cd images, down to under 100 megs. I might still have one sitting here.
Yup Ikaragu dreamcast image. 17 megs compressed. 811 megs uncompressed.

I don't know if this exactly applies to Dreamcast games, but I've seen my fair share of PS2 games that could be compressed to roughly 1/4th the original size of the ISO. Sometimes PS2 games would have dummy data--which I believe was done to make it easier for the laser to read the data.
I have used 7-zip in the past, but for a very small percentage of archives would not uncompress. In my experience, WinRAR has never failed me.

Yep, theres a good chunk of dummy data, but its not 17 megs of real file and 773 of dummy data.
I found the archive, its actually a RAR that was done with 7zip. oh well.

my thought exactly
just tried extracting crysis and 7zip failed at 100mb, installed winrar 3.00 and all is dandy
winrar FTW

Completely correct. Ikaruga is approx. ~19.68 megabytes by itself.
