Hey all, thanks for your help. Finally managed to get it worked out. But i have to admit I've gone both of your suggestions (except I didn't downgrade my device's fw) and also even I tried some other videos from that dude. I'm really amazed that you could solve your issue. The links and stuff that he's talking about is all either missing or outdated and not reliable at all. Normally I never check out youtube for such cases but it kinda helped me to figure out what I was missing.
Turns out yeah it was sigpathes. I was using Hekate and it was messing up at something I suppose. So this time I went for a clean installs from their own github repo of Atmo. And sigpatches from HarukoNX again from github repo. Turns out everything worked fine. Also the tesla overlay was working terrible with hekate and I was assuming that how it's supposed to work. In fact with vanilla atmo, it's fluid as nintento's native UI! Everything runs smoothly. Even some cheats weren't working on Hekate now all of them work (and the games as well)
I bet I messed up at something and got baned because of the wonky settings of it :/
One thing about the switch homebrew scene I noticed, there's like a great tension from developers. Which I can relate. Answering the same question over and over might be extremely overwhelming. I mean no one is forcing them to do such thing. -Except atmo- most of the documentation of the scene is terrible and explains literally nothing. so why are they salty tho xD Just my two cents. Don't get me wrong, not complaining at all.
After all, this is like paying the price for being cheap lol.
