If you are trying to make an iso, then after cdi ripping the image (I may be wrong) but you should run isofix to fix the lba; this will produce 3 files an ip.bin (name bootfile.bin) header.iso and fixed.iso. You can delete the header.iso. Hope that helps.

EDIT I just re read your last post you can't run any dreacast emulators just yet they aren't made for commercial games. With the exception of Icarus which isn't available.
