You appear to me to be in a reasonable position with CDRWin. The DVD drive will accurately read your CDs and that matters. Your Burner will write Session at Once RAW - that's fine.

So you can copy games with CDRWin.

CloneCD shoud also be OK because with SAO+RAW produces the same result (I believe unless anyone can correct me) as DAO+RAW. So, as Deano says, try it with something you know works.
