- When you shrink the screen size in the way we do now, by simply drawing to
- a smaller area, wouldn't it be possible to switch graphics mode on the fly?
-
- What I mean is:
- - Use a monochrome mode while the top part of the screen is displayed.
- - Change to TC mode by HBL interrupt just before the 'play area' is reached.
- - Switch back to monochrome by another HBL interrupt to display the bottom.
-
- That should save lots of bandwidth with a small window, and would be
- possible to combine with the suggestions above if needed.

- Jaguar DOOM uses something similar to 160x200 IIRC, and it looks very nice.
- Running BAD MOOD with a width of 320 will always be pretty slow on an
- unaccelerated Falcon, so the window size will have to be decreased somehow.
- Whether a small window is better than more blockiness is a matter of
- preferences, I think.

- I think it's a good idea.

- Please, do that.
