well technically 1 one of these tutorials the extension doesn't exist anymore, and one of them is just how to make it pixelated which is already what I did in this game with the help of the Worst 30 Year Old Man that is drunk on the internet aka Niven Hedinger but besides that in my new upcoming project aka party incident full game, I use this shader https://samgrady.itch.io/coppercube-psx-shader which seems good rn but thanks for the help! also no I am not going to switch to unity any time soon because that engine is just too complex for me, god bless you windy!.
