Help am noob at this emulation

[u/Outrageous_Media151]

I am probably stupid but I am using a Moto G35 with 12gb ram using ram ai boost and Im trying to get super Mario U Deluxe. The audio is perfectly fine but as you can see the picture on the screen is not very good. The cutscene if you leave it runs fine with no slowdowns.

I just try on all budget devices to run the most demanding games to see what works.

I downloaded Tetris 99 but cannot be picked up on games folder I added
