you might want to move the stack out of the $f800-$fbff area before you
overwrite it, or use $f600 instead :)
also make sure you're copying the right direction (unless you changed to
using $ca00 one of the buffer planes?)
maybe:
	ld hl,$f200
	ld de,$fc00
	call buffer1
;	ld hl,$f600 isn't needed because $f200+$0400=$f600
	ld de,$ca00
buffer1:
	ld bc,$0400
	ldir
	ret
