Calling them and asking will be your best bet
They have a wall of cords if you go right downstairs. If you need a composite (yellow, red,white) cable theyll prolly have one (ps1, ps2, and ps3 all use that cord for standard def) but if you need an HDMI cable they should have that too. Take a picture of the cord and show the guy at the counter. However, if youre looking for older cords like that, check out Lost Ark video games. They SPECIALIZE in that kind off odd older videogame stuff.
In the recent past, every time we have shopped at McKay's, they have had replacement A/V cords for the PS3 on-hand and available.
