Yeah, I've been meaning to check with the composite output, but honestly, I never bothered to hook it up ("Everything's transcoded to component as it is, why use it another input on the TV for lower quality", I thought when setting it up) and considering the huge pain in the ass that it is to wrest the 1070 out of my rack and get access to the back of it (which basically requires unplugging everything just to get it out all the way) I haven't checked yet. I'll see if there's a way I can easily get into it and check for results shortly.

I suspect that recreating it is going to be a bit of a problem for anyone else. While Ico is generally available it's still an out of print game. The Zelda Collector's Edition, however, was a one-shot promo title and typically sells for around $40-50 if you can find it in shops.
