I adjusted the size/position of the screen in kawa-x and U64-X which seems to have had an effect on a backup game I played straight afterwards. I noticed in this game that the screen was off center to the left leaving a gap down the right. I rebooted the xbox but this didn't help.
Prior to this the game was displayed perfectly, a few emus/roms have been installed and another backup game removed from the hd since. The only other thing I did was to delete the save I had for it and start a new game (dash is hacked to allow access to original msdash).
If anyone can shed any light on this problem then I would be very grateful. I don't see how adjusting the size/position of the screen in kawa-x could have any effect on the screen in a backup, but I can't think of anything else that would have caused this.
Might it help if I deleted and re-installed the backup in question?
