yep they exist. but I don't need to solely focus on them. and this entire thread seems to be people saying that fact over and over again. (as you just did as well)
is there some kind of meme I missed or something? I'm confused as to why there's so much hostility in the comments.
I run totk exclusively on my steam deck (I liked the fact that load times were faster on steam deck than original switch)
you will need to find a stable version of yuzu that will work on it and you should be able to get about 30fps fairly consistently with performance mods. (there is a totk optimizer you can run that has a steam deck setting built in. very convenient)
bg3 I highly recommend trying to get the native steam deck version for it. cause it runs much better.
I use microsd cards to move files around. so if you have those I recommend them.
