Currently the colourram address space wraps around at 32kb. This means that if you access memory at $ff88000 you will really be accessing $ff80000 instead.
Memory access to $ff88000 should be treated as unassigned memory access, if there is no memory mapped there (the possible 64kb colour ram model).
