There might indeed be a palette issue, since Neil manages the palette itself.
Or the problem could lie in the use of load_bitmap () that you must have used.
But actually I expect to find it in the turning of the bitmap. In the high color
modes, one pixel uses *more* than one byte. You
can't just turn them around. Weird things will happen. Send me the code and I
will try to find it.
