These types of projects were not so uncommon 10 or so years ago when those consoles were cheap and plentiful. Back then you couldn't go on ebay and buy a color touchscreen TFT LCD for $5 plus an arduino knockoff to control it for another $5, and just download software software libraries and bang out some working code in a morning. Using a 16x2 character LCD was still fashionable, but you could get a monochrome 128x64 character LCD with piss poor contrast for $40 or so if you wanted. And of course you had to figure out the datasheet and write the software libraries yourself because that was new stuff; you couldn't just borrow code from other people's hobby projects because there were none (at least none that used the same LCD controller as your module had).
