Offscreen in which direction? right-left wraparound should be quite good (e.g. Super Bomberman 5 title screen uses sprites wrap for the leftmost character and it's fine with current code)
up-down wraparound is otoh not that good: I noticed it when I fixed the Sim City problem, but my first attempts to improve it were breaking some other games...

I plan to do some more experiments after 0.138 is out (to avoid further regressions before the full release)

EDIT: and good luck with NSS! the menus have always been a mystery to me (and Reip too, iirc)
