I was playing halo2 campaign on my 360 and I noticed that some images get burned into the screen. I snapped pictures of the arbiter's silhouette, burned into the left side of the screen. One of those bigger forerunner robots also got burned into the screen.

Oh yeah...and the overlay...don't forget the overlays of maps on some maps. Usually I see overlays on Lockout. I've seen ghosts of Zanzibar and Headlong when I'm on Lockout, whether I've played those two recently or not. I just had my 360 repaired (it kept freezing). The freezing problem is gone, but I still get the mist disappearance on Lockout and I just noticed an overlay of Headlong while on Lockout the other day, although not quite as noticeable as it was before. I'm sure it's an emulator problem and not one that has anything to do with a processor or hard drive problem because I still notice the differences LordNewt mentioned, like the water being deeper. Maybe they will find a way to correct the emulator eventually. It's really not bothersome, just an interesting graphical enhancement and/or abnormality.
