I've renamed AutoSave.ep to AutoSave.ep.save and when I launched the emulator I got a MEMORY CLEAR message. Then I got the same checksum values as you.

I prefer not to erase the programs I currently have in my 35s (don't want to enter them again.. ).
Anyway the point here, as was established soon after the launch of the 35s, is that the checksum values on the 35s are not reliable as they depend on the calculator context and not only on the program for which the checksum is provided.
