-A enables AGA screen modes, which effectively also enables DblNTSC
which doesn't exist on OCS.

The default screen modes for the console are 640x400 for NTSC and
640x512 for PAL. Which means that a PAL or NTSC interlace screen mode
is selected automatically, unless you have an AGA machine and -A is
given. In the latter case DblPAL or DblNTSC is selected.
