The quest to build the perfect portable Nintendo 64 continues, but we imagine we'll stop seeing so many disparate designs soon. That's not because Bacteria's latest bulbous handheld has achieved perfection -- far from it -- but rather because he's provided a 2.5-hour, step-by-step video guide to help you build it from the ground up. And hey, the system isn't too shabby, either. The "iNto64" portable features integrated Controller, Rumble and Expansion Paks for complete N64 functionality, built-in speakers and a headphone jack, rechargeable batteries for up to three hours of play, even a video-out port if you get tired of staring at the ubiquitous 5-inch Sony PSone LCD. The only obvious oversight is controller ports for more inputs -- seems our buddy Bacteria wasn't a big fan of GoldenEye. See it play some of N64's other best games after the break, while we dust off our gamebit screwdriver. Obvious though it may seem, know what you're getting into before you do likewise; ripping up classic cart-based consoles isn't for the faint of heart.
