I agree with Siggi
MORE BOREDOM PLEASE
Have I got this right, You are executing code from WITHIN THE DISPLAY FILE????
I never cease to be amazed at some of the things I see in this forum

Re: While i was bored...
Kind of, excuting code from within the D_FILE,
there are 2 CALL nnnn instructions 1 in the first 3 bytes of the D_file, that jumps to my code so i can manipulate what actually gets displayed and when... the other call is after the scroller on row/line 10 that switches the D_FILE pointer back to my first D_FILE for the blob things...
then there are LD A,(HL) and RET Z instructions either side of the smooth sideways moving ZX81 at the top, these instructions are used to ab-normally shift (by 2 pixels per extra cycle) where the ZX81 is displayed.
thats about it really.
the CALL nnnn, JP nnnn trick is used by a few other programs.

This works great on a vanilla Zeddy + ZXpand, not managed with the other one though.
Great stuff mate.
