Can I get a xbox emulator to work ?.

Today I was messing around, and I decided to see if I could get a xbox emulator to work on any of our machines. I tried my Girlfriends desktop, and all three laptops. Could I get it to load any games or run, and how did it turn out. We have older machines so it was interesting to see one run the emulator and start the game. She has a dell Optiplex desktop with a graphics card installed with Nvidia graphics and sound. She also has a old Latitude e6500 much like mine but with internal graphics. I have both my dell Latitude e6500 with nvidia mobile graphics, and the HP probook with nvidia graphics. Only the probook is a i3 and everything else are core 2 duo machines. Only two machines are being shown because midnight is a jerk and he kept walking on 2 of the laptops so I put them up.
