[comp.sys.amiga] Black Belt video adapter - limitations?

jeh@elmgate.UUCP (Ed Hanway) (01/09/90)

The Black Belt device looks interesting, to say the least, but
it seems like any external devices like this are going to have problems
with the pointer (or any sprite), since there's no way to tell whether
video data is coming from a sprite or a bitmap. This would probably cause
at least two problems:

	1. In the HAM-E mode, the pointer would affect the picture beneath
	   it, much like a menu on a regular HAM screen. This does NOT happen
	   in normal HAM mode.

	2. If you move the pointer up to the first scan line, and obscure some
	   of the magic patterns there, the screen would revert back to
	   medium or high res

And what would happen if you put a menu bar on one of the new mode screens?
The user presses the menu button, and the screen mode changes? (Into high
res -- hmm, this might be a "feature.")

Any comments? Am I all wet?
