Decompile Runtime Image?

[jonesgh]

We've lost the source code for a Smalltalk application. All we have is a .icx runtime image. I understand that since Smalltalk is an interpreted language it should be possible to decompile the bytecodes in the runtime image into some form of source code. Is that possible?

My first reaction is that you are out of luck. The packaged ICX is basically the equivalent of a compiled EXE.

Could you possibly decompile parts of it from the ICX? Maybe.

Would you ever be able to recover it to a state where you could make changes and then repackage it? No.

You need to find the Smalltalk repository (.DAT file) in which the app was originally created.
