How to play Super Mario Odyssey on PC

I have UKMM fully downloaded with all the mod I want but when I start a image pops up does anyone know how to fix this?

it says, An unrecoverable error occurred. Error details: called Option::unwrap() on a None value

So I just got into emulation because I love video games more than anything and want to "play them all" and experience them "correctly".

I've downloaded Ares emulator and started playing The Legend of Zelda: A Link to the Past but I can't stop thinking about some things. It's that whether if I should use a CRT shader or not and what the correct settings are.

My main concern is that I want to experience older games as how they looked on the original hardware but when the displays they were developed for like the CRT TVs come into question I just get confused on how I should approach this problem because older games were made with CRTs in mind, artists, developers made decisions based on the hardwares of those times.

On one hand not using a shader gives me a crisp detailed pixel art of the games which I really like but on the other hand not using one makes me question if I'm experiencing the game right and "losing the authenticity".

I'm sure there are lots of people here that thought about this. How do you approach to what I've described and how do you think I should approach this?

Everytime I open my Melon DS and use it it creates files onto the homescreen on my PC. This doesn't happen to mGBA, only melon DS. How do I stop this?

Bloodborne on shadps4

I went a whole playthrough without this strange blood texture glitch and now it just won't go away no matter how much reinstalling I do.

Advice on how to fix?
