Image format 6521 is the 32-bit Spur image format used in Squeak 5.0.
A Spur VM is required to run this image. Tim's latest Scratch work is
updated to the 6521 Spur image format, so an interpreter VM can no longer
be used to run these images.

Squeak 4.6 and earlier will work with the interpreter VM, and I expect that
an older Scratch image should work also, although I do not know exactly when
Scratch moved to Spur 6521.
