Me personally, I usually play the original quadrilogy on N2DSXL, I don't like playing Game Boy (Color) (Advance) games on a big screen like the PC. It feels odd to me.
You probably are traversing a very difficult period where everything seems black but these are your feelings talking, trust me. I'm also going through a phase where I said such things and did things I really regret but I managed to get professional help and recover slightly for now. Hopefully...
I played through Super Mario Bros. Remastered. I really enjoyed it! It's been a long while since I played the original Super Mario Bros. game and I had a lot fun! Definitely recommend it!
Mostly on my PC, I kinda lost interest for newer titles so emulation has been my way too go. I'm also to lazy to plug my Wii so I'll play my games on Dolphin.
