Hm... what would the timespan between the two RESPs be then? 2 cyles?

IIRC yes.

I assume in case you'd loose 2 pixels then, resulting in 14 pixel wide sprites?


You mean JSRing to the exact next extruction? (And then sometime later restore the stack manually, yes?)


Phew... if this all works as I understand, this'd be a very cool thing to do.

Yup. :-)

Didn't you seek for a use of this technique lately? ;-)

Yes, and IIRC remember I have successfully tested this when experimenting with the bunkers in my TomInv demo (10/7/2002: check the outcommented code starting at line 826).

Have fun!
