i think it is about image format, since Pharo adopted one, introduced by Eliot
(6505 or 6504 .. don't remember one) .
And squeak VM does not supports that format.. but if i remember it was
changed lately
and you added pieces to be able to read new format..
If that's true, then i don't see other reasons why it shouldn't work.
