I vaguely recall discussions about this sort of thing; a way to bundle an image with a vm in the days before Apple finally copied the RISC OS application structure. Back then - and maybe still now, I wouldn’t know - Windows was able to bind assorted resources into the same file as an executable. At one point in ancient history VisualWorks could do that as a distribution mechanism.

For RISC OS you just need to save a normal file inside the !appdir, for OS X I’m guessing you can save a normal file inside the bundle, for Windows… no idea, for *nix there are probably 700 different ways with 7000 opinions published as to why each one is stupid, or brilliant.
