I have a Pre-prod special edition cart update to the latest v1.05.
I am using it on a VGA modified 2600.
While playing games I have a some issues
1) screen is offset to the right (and in some games I also get a number of horizontal black lines) [see attached]
2) many games start and play perfectly (i.e. Donkey Kong) but for many others I cannot play. No sound or the joystick does not respond (i.e Activision Decathlon)
3) during a game the screen will go black for a couple of seconds and then reappear. This happens every 15
Any ideas / comments?
