the second will have really bad picture because it converts 480i (RCA signal) to 1080p.
first one is quite fine. wii have component output (480p) so this thing will just only upscale the picture.
I own wii2hdmi, it's not bad :)
So I'd make a arcade cabinet based on Raspberry PI.
Install a linux distribution and tons of emulators (metal slug !).
Not too big LCD screen + raspberry pi + 2 x (joystick and buttons connected to rasp. pi via dual strike) + nice speakers.
My dream :rolleyes:
