- vidarh 3y agoYou bank switch then. A common use would be to e.g. be able to use the ROM to load code into the RAM under the ROM and then bank switch, but also e.g. for extensions where you might want to first copy the ROM into the underlying ROM, and then patch whatever changes you wanted into before bank switching.
