I would HIGHLY suggest getting a Pioneer A04 for DVD backups & a 100% Clone CD compatible CD burner for you CD based games. The Pioneer A04 works great for the dvd based games BUT it cannot make a 1:1 copy of the cd based games due to the copy protections on CD based games (DVD games don't have copy protections)...
As lufcfan pointed out..... DEFINATELY get the Messiah or Magic 2 modchip..... They both Direct boot everything......
