Just to restate the obvious, this is apparently an incompatibility (or
maybe bug) in VBox.

I don't know why, thus I don't have a direct fix or workaround.

You may wish to explicitly say that "Legacy" is not meant for VBox and
"won't work" (yet?).


On a barely-related topic, I wonder if it's wise to make people
download a 400+ MB .iso again when they already have the first one.

The obvious solution would be to use something like XDelta. Latest
(circa 2016) with premade binaries for Win32 is apparently 3.1.0
(although DJGPP has a much older [2002] port of 1.1.2 under
/current/v2apps/ as XDLT112B.ZIP).

N.B. If really desperate, maybe contact uHexen2 (DJGPP) dude, he
half-ported XDelta3 there, I think.

   (206 kb)

A quick try (on Win7 64-bit) shows that it works correctly, and the
"diff" is "only" 940 kb (less than 1 MB).

Would this be worth suggesting to users? It would certainly save download time.

Of course, this only works if the .iso files are kept relatively
similar. If they are meant to diverge (or that becomes unavoidable in
the future), then it's pointless.
