I wanted such a LDP model, just for being more flexible while capturing. I would rather buy 2 LDP models, then going your adviced route. Going such a long signal route, would degrade the material for sure. There are PAL LD-games outthere, at least SailorSat´s Dragons Lair is in PAL, for example.
Anyway, there is no interest in captured dumps, so this discussion is pointless.
