Looks like I'm getting there ... gradually but still some off by one errors.

[ Show youtube player ]

The playfield is currently 288x256, i'll need to hide 16 lines at both the top and bottom of the video to give a playfield size of 288x224.....(ohhh my, I wonder why I chose that playfield size > )

The reason this is so complicated is for performance. The playfield is 21 words wide so on 7 of the 8 available even frames I have to make 3 blits, for the odd frames I'll probably copy the blits to the other buffered screens.

Hopefully, I'll get good performance.
