So I ordered the RetroTink 5x Pro and everything works great on it. Deinterlacing, scanlines, you name it. Am a little confused about all the resolutions on my 1440p monitor but thats fine for now =)
Anywho, I started to play some Wii and Gamecube games and I noticed something. First of all, kind of dithering in the Wii-menu. Like small flickers sort of? And then I fired up Wind waker only to be met by horrible vertical lines on the screen. Here it is :

Nothing like that on the PS2.
If there is anything to note Im playing the PS2 with Motion adaptive interlacing and retrogamingcables.co.uk’s PackaPunchcables. And with the Wii Im just using the original component-cables. Might be a cable issue?
Anyway, would like some help! Thanks in advance =)
