Well, my friends and I did some tests and here are the sad results:
What we had:
My Xbox (Modded).
My Neighbor's (Modded and EvoX installed).
My Cousin's (Non-Modded).
My Brother's (Modded and also V1.1).
Game:
Moto GP (DVDR)
Moto GP (on HDD)
Moto GP (retail)
STRATEGY:
Test each Xbox with Moto GP DVDR, on HDD, and retail version (retail version was only version working on unmodded obviously). Each test was only 5 minutes apart (just incase the servers were too flooded with people).
Well, sad to admit it...but here are the results:
The only combination that worked was the Moto GP (retail), on Xbox (non modded).
We did this test this morning and I later did the tests this evening with the same results.
This sucks
I hope it's fixed
P.S. - We took my brother's Matrix mod out and it still didn't work even after that. That just boggles my mind.
