hey Eric ;-)
anyway, got it open here, found the templates in an old folder - heh the archive works ..
and Intro, mainA, mainB, etc. are selected with
43 7E 00 08 7F
43 7E 00 09 7F
43 7E 00 0A 7F
43 7E 00 0B 7F
43 7E 00 0C 7F
43 7E 00 0D 7F
with F0 at the start, and F7 at the end.
as i recall, this works.
those templates were pretty good for getting into the guts of the box in realtime.
i thought they were in the Files section but apparently not.
