Hi, I have recent purchased a 800XL (PAL) and paired it with a SIO2SD external drive, all appears to work fine, expect on a lot of games I'm getting a corrupted sprite, and I'm not sure why, would anyone be able to shed light on what may be causing this? Configuration, software, PAL/NTSC issue, RAM or Antic failure? Note that some games appear to run perfectly. Also passes memory tests fine.
I apologize for the poor photos, but you can see the corrupted missile or sprite running vertically down the display, these will follow the player or enemies.
Any help would be appreciated.
