Thanks, i did notice, and was going to fix. It may be worth adding that tip to forum help!
It is possible the line count isn't exact. if the PAL frames are identical, does it matter? It should be possible to set the value at rasterend (currently 56) to get the exact line count. Then to make screen bigger/smaller change in steps of 16.
This version doesnt call any kernal IRQ services (keyboard, time etc). It would be possible to add these, by examining the kernal code to find the routines. Adding code to call these after "fast1:" label should work.
I wanted to make a simple general purpose program to demonstrate the principal. Just feel free to adapt/improve!
