Xbox 360 Game Compatability

So Today I was doing some compatibility testing with the Xbox 360 console and the original Xbox Games. Interesting Findings.

Here is a list of the games tested, in alphabetical order.

Apex
Crash Bandicoot: The Wrath of Cortex
Crimson Skies
Dead or Alive Beach Volleyball
Enter the Matrix
Fable
Fight Night 2
Genma Onimusha
Halo
Harry Potter and the Prisoner of Azkaban
JetSet Radio Future
Kill*Switch
MVP Baseball 2004
NBA Inside Drive
Need For Speed Underground 2
NHL Hitz 2003
NHL Hitz Pro
Pirates of the Caribbean
Prince of Persia: Warrior Within
Project Gotham Racing
Project Gotham Racing 2
Sega GT 2002
Simpson's Hit and Run
Spy Vs. Spy
Star Wars: Knights of the Old Republic
Star Wars: Knights of the Old Republic II
The Haunted Mansion
The Simpson’s Road Rage (Platinum Edition)
Toe Jam and Earl III
Tom Clancy's Splinter Cell
Tony Hawk's Underground
Tony Hawk's Underground 2
True Crime: Streets of LA

Two games could not be tested.

NFL 2k5
Counter-strike

I could not locate these two discs.

Now, only one of these Worked. Halo. There were a total of five Microsoft Studios Games in the bunch

Crimson Skies
Fable
Halo
Project Gotham Racing
Project Gotham Racing 2

One out five... you would think these would be the most compatible. Only 20% of the games we own are compatible.

Therefore, that is a total of 33 Games. Only 1 of which is actually compatible

Here is the list of games that we own that are supposed to be compatible

Crimson Skies
Fable
Fight Night Round 2
Genma Onimusha
Halo
Kill*Switch
Sega GT 2002
Star Wars: Knights of the Old Republic
Star Wars: Knights of the Old Republic II
The Simpson's Hit and Run
The Simpson’s Road Rage (Platinum Edition)
Tony Hawk's Underground 2

So that is one out of twelve... hmm... 8.3%... that is not good....

Now, I did not check to see if there were updates to any of the games, this was strictly putting them into the xbox 360 and seeing if they would load.

Grand Total of Games that will work straight out of the box. One. So that's one out of 33... 3.03%.... good ratio... yeah, that's it.
