Build your own arcade
All those hours spent pumping loose change into Defender, only to die three seconds later. Now THAT was the way to spend your youth. Desperately heaving change into Gauntlet so you didn't get "Game Over". The buyer's remorse you'd inevitably feel as you jammed the last of your pocket money into the machine, only for that dang asteroid to hit you, and realising that was it for the week. No money.
Now you can recreate those days with, so it claims, NO TECHNICAL SKILLS!
MAME, the ubiquitous arcade machine emulator, is the software component. Now you can buy the hardware and recreate your own Defender cabinet. Or whatever other machine used to beat you into submission within seconds of you depositing your hard earned money into it. I was Enduro Racer's bitch for a long time, so it's a shame you can't recreate the more exotic cabinets like Enduro, Pole Position etc... One day no doubt.
Buy enough of these kits, and you can open up your own retro arcade. All you'll need is some gum mashed into the carpet, and a surly old man handing out change behind bullet proof glass to complete the experience.
