Maybe I could leave the command code check out to gain space. But I
think there must be at least one other location to patch: ProDOS needs
to KNOW that it can now use 640 blocks. The FORMAT routine needs to
format more tracks and to use 160 tracks I also need to make it seek
to half-tracks.


It shouldn't be so hard to do 512.

Are you supposed to be able to write half tracks?  I always thought
that the half track copy protection worked by not using the neighboring
tracks.
