If I can't repro it with this chip, if you want to mess around with it

to use 16bpp mode as far as what mode you write to the chip, and then
double all the x coordinate values for things like offset, width, and
pitch. You would have to do that to the accelerated routines also.

How much is each line offset when you have the garbled stuff? I

is it a couple pixels, half the total width, something else? And is
it always the same for each line (or can you tell)?

Each ghost is 1/3 of a screen horizontally from the other ghosts. I've
been looking carefully at test patterns to figure out what is going

on.

Since the ghosts are 1/3 of a screen apart and not 1/2...

If this is similar to the old Mach64, for 24-bit you have to use 8-bit mode and
multiply all horizontal values by _3_.
