Dogg I'm sorry but I am not prying apart my old janky ass Galaxy S4 and sticking it in a Mad Catz controller chassis so I can play the bing bing wahoo. I get what you're saying, I like little DIY projects, but there's just so much that can go wrong. All it takes is for one doofus to stab a battery with a screwdriver, he blows himself to kingdom come, and the whole project's dead in the water. I figure if it were really viable, we'd see more homemade game console kits for things like Raspberry Pis. Those do exist, but they're more, like, designed around getting an understanding on how you'd assemble a prototype game system rather than one you'd actually want to use day-to-day. I'm sure there's a lot more that can go wrong that I can't think of at the moment, but I'm just not feeling this idea.
