] On the other hand, maybe it's better to use a ON INTERVAL command. I'm not
] sure how it works, but if it's interrupt driven it might be faster than
] checking S#2 bit 6. Besides, I don't even know you CAN read S#2 in BASIC
] since the interrupt routine always expects S#0!
You can read S#2 in BASIC with VDP(-2). But ON INTERVAL is indeed the
preferred solution to synchronise graphical updates with the vertical
retrace. And if plain BASIC is too slow, there still is KUN-BASIC to speed it
up significant.
