I can only say : that will be BIG
the connector of the xbox and ps2 are largely the same
(I know it's a shitty image, but it's just that you see the connectors)
The yellow one (video) i connectod to my tv-in ,
the red and white one i had an adapter for, so it would come to only 1 connector.
Plugged that into the audio-in.
Hope this helps and that i wasn't to chaotic
