I've downloaded some PSP games from torrent sites. Some of them are in 1 file in ISO format. Others are in 20 or so smaller .rar files or other files. What do I do to make all of these smaller files into an ISO file? I've read a few posts about vcdromX and was wondering if this was the best way or if there are other ways. Any information or guide would help a lot and would be greatly appreciated.
