As per Ziggy's request...
Quick post about an interesting outfit called "RetroGameBoyz." I recently purchased their C64 controller. They don't have a website, but are on Twitter, Etsy, and eBay.

Many of these consoles came packed with controllers that aged poorly, or were downright awful from day one.
Since I'm familiar with these old systems, I'll walk y'all through things.
Atari 2600 / C64 controllerBoth the Atari 2600 and C64 utilized one-button joysticks. These days, many find it easier to use a Genesis controller to play 2600 games; however a Genesis controller can damage a C64. That's where this comes in. Why the two action buttons? Because many C64 games were platformers that used up (on the joystick) to jump. Here, up is also mapped to an action button, so you get that NES feel. Brilliant. As mentioned, this is the controller I own. Great build and functionality. Makes playing these old C64 games so much easier.
MSX controllerAnother two-button deal. Authentic old MSX sticks and controllers are extraordinarily tough to find, and can be quite pricey. Seems like a solid replacement.
Sega Master System controllerFor those who wished their Master System controller felt more like an NES controller, I suppose.
Amiga controllerAgain, easier than a a joystick.
ColecoVision controllerThis is the most interesting one. For the uninitiated, the original ColecoVision controller was one of those "keypad" things. It worked fine for certain elaborate strategy type games, but was way too excessive for the arcade ports of the era (which were the most popular games of all). You don't need a big keypad to play Donkey Kong and so on, and most CV games seemed to just ignore the majority of available buttons. This controller is well-suited for those simplistic action titles.
Atari 7800 / 2600 controllerThe Atari 7800 used a joystick with two side buttons. It's a tad awkward. There was, eventually, an official controller available, but it's pretty rare. And European, from what I recall. This here controller is a nice alternative. Works with 2600 games as well, naturally.
