Not neccessarily. If the boot disc you downloaded boots w/o problems, yes you can play burned/imports(If you are using NTSC jap) by swapping discs but will need teh top open when you swap and keeping the spin button down firmly. The bootdisc should tell when to swap discs. If the boot disc does not boot then buy a real boot disc.(maybe from a local import game store or from here http://www.ps2cover.com/breakerprousa.html )
