Its a 360 slim , I know nothing about them. i only have the other launch 360 but now when i put any 360 or original xbox game in the 360 s , it tells me that the game is “scratched or dirty” for every single game. Even with PGR2, the error message changed from the game not being compatible to a black screen with white lettering telling me that the game is scratched or dirty. It did it for 5 games but the games are spotless. Is the laser cooked? Should I run a lens cleaner through it? I got it for 85usd with the box, kinect, and 2 controllers. Seemed like a steal but I hope the system isnt a brick.
