I don't think that asm progs will be impossible, it'll just be like
programming for a multisync, or different resolution screens on a computer
- there'll be a global or 2 somewhere that you can read that'll tell you
whether or not you're on a 92/92+, or what size the screen is. Then you
just have to make 2 sets of graphics. Include an installer that works the
same way as an installer for ppc/68k, and it can automatically choose the
right graphics. The development time shouldn't be much longer, if you
develop the images for the highest resolution possible and sample down, the
touchup shouldn't be too hard. The only problem that I can see with a
smaller screen is a smaller menu, but I imagine that it'll be handled in
the same way as a long custom menu on the 92.
