...played around with it a bit more and here is what I'm seeing - I CAN write to patch 000-499 but I can't write to 500-999. Is that right? Seems to contradict what the manual says - I was thinking I could save to patches 000-004, 010-014, 020-024, etc, etc all the way up to 999 but it looks like I can write to a different range. Did I just misread the manual?
