Wind noise wasn't too bad; I've heard worse on radio programmes on the BBC, so I certainly can't complain. One question about the playstation emulator, does it retain it's 5:4 screen ratio when fullscreened on a widescreen display like the Pyra has? I think that's the first time I've seen PCSX running so thanks for that!
Edit: Yes, the screen looks plenty bright for outdoor use at least on max brightness. You were connected to your phone via bluetooth or by wifi sharing?
