Oh boy, don't get me started on the Nintendo 64 controller. I hated it. Hated the weird layout, hated the fact the analogue stick would always get loose. These days, Nintendo wisely offers alternatives to their "wacky" controllers in the form of Classic and Pro pads for the Wii and Wii U respectively, but we were out of luck with the N64.
Oh, except for Alex Clark, who decided the hell with it, and made an N64 Pro Controller anyway. Reshaping the original casing, bringing in a second stick and moving the buttons around, he's got something that not only looks like something Nintendo might have released, but which will work on an actual N64 and play games just fine.
It's the logical conclusion to an older project of Alex's we featured here, where he stuck two pads together to let you play games like Pod Racer a little easier.
