I doubt it... according to the docs, you can create V6 files (they're
included "for completeness") for the extended memory model, etc. but I
don't think you can actually include graphics. The character-mode ZIP
won't display them, anyway (now if someone'd like to do a svgalib port to
Linux, :).
: or even better - is there a way to call C functions from within Inform code?
I doubt it as well, since the Z-machine format is infinitely portable and
machine code is not.
