Not "BadMood specific" :) Anders said, that BadMood developers want to
make the program networkable. So my thoughts were like this:

1) BadMood, to run fast on Falcon, has to run in supervisor, because it
wants to utilize as many CPU power as possible.
2) supervisor stops multitasking.
3) mintnet needs multitasking
4) so, is it currently possible to run games like BadMood networked using
   MiNT-Net?
5) answer: no, its completely impossible.

Hence the idea. But if you all think its more dangerous (because of normal
programmers' lazyness), than advantageous, I can cancel this function.

Besides, if BadMood steals the VBL autovector for itself and exists the
VBL using RTE, it won't multitask anyways.
