Yeah, it's kind of a personal thing, isn't it? I can appreciate the composite output, and sometimes Pixel Perfect is too clean (esp. for text), but when I play an actual console I like it to be pixel perfect. When I actually do emulate, I try to muddy it up a bit with CRT/NTSC filters (although this depends heavily on the game). Maybe I just like bending the hardware against its will, lol.

I like seeing everything in new and different lights, so if it were easier with my current setup to switch between composite and SCART, I would, but my retrotink is out of ports lol

I only use S-Video for the n64 because I don't have HDMI modded, and it is kind of a mess visually vs. emulator for obvious reasons (the famous smear filter, and I don't have the Gameshark or whatever to disable it)
