I built a 64bit VM a few years ago and converted one of my images. I had some success but I don't remember the issues I had run into with the image conversion.

Curious: what would you do if you could have a huge image?
Good question. The original Squeak 64-bit image is about five years old now, and does not seem to have attracted much interest of a practical nature:
http://squeakvm.org/squeak64/dist3/Squeak64-3.8g-6548.image.tar.gz
An updated version of this image, suitable for use on current Squeak VMs, is here:
http://squeakvm.org/squeak64/sq64-dtl.zip
You do need to build your own VM to use this image. There is nothing exotic about it, you just have to click the "64-bit image" checkbox on VMMaker to activate the 64-bit object memory version.
John McIntosh with support from ESUG is planning to do new work for a Mac VM, including 64-bit object memory support. Hopefully this will encourage new interest in the topic.
Help needed: Currently there is no way to convert new images (Squeak trunk, Cuis, Pharo, etc) into 64-bit format. If anyone has some expertise with SystemTracer, it would be good to get this working.
