Both our 1084S's can display PAL. But AMOS like checks the line
frequency. It will only display NTSC from our 2 A500s. My A3000
has a jumper to declare PAL/NTSC. With this set to PAL AMOS will
display a PAL screen (but I don't think it likes to.)
A 224 line screen will generally fit on an NTSC monitor (or TV).
So we can all compomise :)
I found myself checking for the maximum lines, and then placing the
little scorebox screen, high score screen, current standing, etc., in
a different area, after requesting the screenmode parameters.
I keep the actual playing field a bit smaller than an NTSC screen,
and try to fill in around it with scorecards or something for PAL
users.
IMHO, it just doesn't matter as far as gameplay goes. And Sprites
can only look *so big*.
An AMOS limitation, I'm afraid.
