Ripping Question

[Moloch]

Ok, just ####ted ripping and I have a quick question. The info I'm using says that when the game rips it'll rip into at least two files, a trackxx.iso.gz and a trackxx.raw.gz, is this always the case? I've just done the ripping part on two different games, (VF3tb and Wacky Races) and they both came out with just the first trackxx.iso.gz file. Is that ok, or do I have a problem on my end to try and figure out and correct. Also what's the best way for unzipping the files? I used winzip and it extracts but tells me there garbage at the end, normal or is there a better way?
