Yes, but please note that the obvious solution (loading all the stuff into
memory and then moving the part that should go into RAM2) is wrong, because
BANK is overwritten when the whole file is loaded.
As far as I remember, the Atari is able to have separate chunks in an
executable file, where each chunk has it's own header, and is loaded to a
different address. The last one of these headers has a special marker. If so,
the solution would be to slightly modify the standard startup script. Just
include both headers (place the second header into a segment named HEADER2 or
similar). Then change the linker config so that each one of the RAM1 and RAM2
memory areas has its own header.
Maybe one of the Atari guys can comment on this in more detail (or correct me
if I got this wrong).
Regards
Uz
