Heh, yeah those are the original CT posters from the SNES box. I still have the cartridge. Best. Game. Ever!
About the chair, yeah the front is torn up but whatever, it's still comfortable. No need to spend money on another one, I'd rather buy more music.
And as for the shelf brackets... I mounted them high so that I could put another shelf above in the future if I ever wanted to. Plus I was too damned lazy to pull my heavy ass desk way out away from the wall
