Optimization, my friend, optimization!

How about adding 320 instead of multiplying by it? i.e.

        poke(a+q+xmin, ...)
        q = q + 320

This would be much, much faster. And since write_buff() gets called a lot ...
Also see about stuffing some of your calculations in a lookup table, or
at least sticking predictable values in a table to reduce the amount of
multiplications you have to do. Mults and divs kill execution time.
