4:3 is squashed pp isn't. On the Switch screen at least.
From my limited understanding all pp does is make the pixel a perfect square, making the image look as the developer intended. 4:3 gives a horizontal stretch to the image which I am not a fan of even though it's a more accurate representation of how it used to look. I only play this stuff handheld. I've only played alttp through it and it looks perfect to me. Not tried any others yet.
Watch the digital foundry video on it. You should be using 4:3 to see the graphics as the developers intended (you can see this yourself as circles are squashed in pixel perfect). Pixel perfect is only for CRT TVs which will distort the square pixels to 4:3.
Cheers Kreeeee, how are you pal?
Few more questions:
1) Download games or buy physical copies?
2) Any free games available? (worthwhile free games).
3) I need 2 more pads for 4 player mode, any particular ones you guys recommend? Maybe some sort of adult sized controller for when I get time to play on my own??
I'm great thanks, how are you keeping?
1) Physical is almost always cheaper for new games, and you can make use of the second hand market. Storage is also an issue even with my 512GB SD card.
2) Paladins is a fantastic free game and lots of people recommend Warframe, Fortnight, and there are a few mobas. There are some great demos such as Dragon Quest 11.
3) Get a pro controller, and an 8bitdo adapter to use your Xbox One (newer Bluetooth controllers only) or PS4 controller.
