Sorry, I don't understand.  Those macros are evaluated at compile-time
against version defines coming from your SDL headers.  It doesn't do
anything at runtime.

320x240, not 32x200?

Only difference that Hatari has in flags is that it sets SDL_HWSURFACE flag
for fullscreen. In both fullscreen & windows mode it sets SDL_HWPALETTE.

First you can test by starting Hatari in non-fullscreen, second you could
try with your tester.

I guess SDL_HWPALETTE is relevant only for 8-bit more, so it would seem
a bit strange if that's the problem...

You cannot specify the flags on the command line currently.

You can change the flags manually in	src/screen.c::Screen_SetResolution().

Actually, I started to think that the joystick thing could be quite
inconvenient for the user.  He would need to use Hatari options dialog
to switch to normal joystick after he's handled the key press.

Wikipedia didn't say whether the device has X server:

If it has, wouldn't it be more convenient & easier just to launch something
like xvkbd with Hatari (like some people do with other emulators on N8x0)?
