[Vm-dev] 64bit squeak VM to run 32bit images? Catalina

[Clément Béra]

Is there a tool to convert 32 bits images into 64 bits images?
I know it's possible through the Spur64bootstrap in the VMMaker packager.
But is it possible to do it with the ImageWriter? Is there an easy way to
load the packages and do it?
Sorry I'm not on squeak-dev, maybe I should be.
