CIAs also have some write-only registers.

Even with extra hardware it isn't that useful because you can't access hard disks (unless you implement HD driver, filesystem handler and everything in your freezer code..). Floppy disks are slow and have limited space. Compression is also relatively slow.

but maybe it is possible to make save file on real Amiga and load it with UAE?
