please refer to plus4encyclopedia/500249 for free addresses. for example at $fdd0 the ROM banking register will conflict with your proposed solution. Perhaps you should use a 128 byte long window from $fe00-$fe7f and do a NeoRAM (implemented in SideKick) compatible solution so the (although very few) existing software using that can run on your hardware too.
