The Raspberry Pi is a fantastic little low-powered device that can do all sorts of things, and we've certainly seen our share of video game related projects for it. This one, from Instructables user Zaqq, takes it above and beyond, and turns the Pi into a completely portable retro game centre.
Like our own all-in-one retro game console, Zaqq's project uses RetroPie to get all the emulators set up and working on the Raspberry Pi. From there, the machine gets stuffed into a briefcase with a cheap screen, hooked up to a battery pack, and then mounted with pick and pluck foam. Its ends up looking great, and it's functional to boot. We've seen a similar setup before, but Zaqq's guide on Instructables is a bit more clear, and the end result is much cleaner-looking.
