Yub, just need cable and converter box.
And you said RGB to Component cables. Did you mean to say: RGB cable built for the component box? Yes genesis does not need any internal modification, the cables themselves need a few minor parts to get a correct signal. Also Override these boxes actually pull sync from Composite Video NOT the sync line, which makes it even easier for the Duo-R.
So Luc are you getting the RGB to YUV Component Box?
