- One thng I haven't seen mentioned that I'm curious about. Does
- anyone know if the Falcon has retained the ability the STe has to fine
- scroll the screen? The reason I ask, is that this would mean a lot of
- games would use a memory area greater than a full screen for efficient
- scrolling in the play field. Double buffering these would take up even
- more memoory, but of course the trade offs in speed and smoothness of
- scrolling would be worth it. It's a shame the base model Falcon is one
- meg, as with the graphics capabilities, this will restrict many
- programmers as much as the large number of 520's sold did. I hope enough
- machines get sold that companies will be able to risk releasing 2 meg
- minimum games, as they recently have with one meg only games. Reading
- interviews with programmers in various British magasines, it would seen
- a significant ammount of time is spent trying to make a game fit into
- 520k once it's written. Same as the old single sided disk problem that's
- now a thing of the past.
