Question about Gameshadow

Gameshadow allows me to find the patches that I need for both my games and my components (found ATI drivers). If anyone is familiar with it do you know why on some of my games it shows unsupported version. For instance it says that on The Movies ( I also have the expansion), WildLife Zoo, Caesar 4, and the Godfather and next to it it says unsupported version and not highlighted. These games arent digital downloads and were bought at gamestop.


System specs: Windows XP SP2, E6300 C2D, Liteon x16 DVDRW DL w/ Lightscribe, Gigabyte 956p-DS3, Soundblaster XFI Xm edition, Saphire x1900xtx, 4GB Corsair XMS2 ddr2-675 RAM total, VX922 Viewsonic 19" LCD monitor, 2.1 Klipsch speakers, 2x WD Caviar 250GB SATAII 16mb hard drives, 2 huge internal fans not including intels stock fan, and cable modem connection. This is just a gaming system.
