If you have a load of ROM that can also be paged in, then it might be quite interesting. It would get past the vic being hard coded to see character rom at magic addresses. Obviously you'd want to port 3-in-1 software from the plus 4. You'd lose $00/$01 being able to page in/out the kernal and basic, but you probably want a new set of roms that knows about the extra ram anyway.Received on 2018-05-25 00:00:02
