i would hate to burst your bubble.. but, WinScreenMode was previously
known as ScrDisplayMode (from memory) proir to palmos 3.5 - you can
change the display depth on any palmos using the WinScreenMode API
as long as it is 3.0+ - the API names were renamed, however, the traps
remained the same (hence, they are compatible)..
this 3.5+ discussion is total crap - 3.5 provided support for 4bpp
via this API, previously, it would only allow you to change into
1 or 2bpp..

if your not targeting 3.5 - just put up a:
"sorry, your device is not supported"
if you cannot change into color/4bpp as required.. you dont need
to put 1bpp bitmaps if you dont intend to run your application in
1bpp - you can check the display abilities and os version prior
to running your EventLoop..
burning, on my website (www.ardiri.com) shows you how to do this,
it requires a color device running 3.5+ in order to run. :)
