Seems some new VC games now have talk about "enabling Interlace mode with component cables" in their descriptions, some were even updated for it (I redownloaded Cv4 because it said there's a new version). I suppose that means they can do prog scan now since the other way around makes little sense. When was that added?
Yes, I plugged my Wii back in and bought a points card. Now grabbing Story of Thor, Zelda LttP and a third game for up to 800 points I still have to decide upon (tending towards Wonderboy or Dragon's Curse, those are from the same series, right?).
