I like this guys channel but I have to admit some of his videos are extremely misleading I used Windows 7 as a daily driver on my old laptop for a while before installing Linux on it and I watched Youtube and used Discord just fine.
When it comes to the viewing angle thing, on my regular DSI the screen looks fine from basically every angle you'd be actually playing from when you look at it from the top down it gets a little dark. Don't know about the XL though.
A while back I installed evilnat custom firmware on my ps3 then I forgot about it I wanted to play online recently so I updated my system and now it wont boot to the login screen. Is there anything I can do? I can still get into safe mode.
