Super Nintendo Classic Coming in September (hollywoodreporter.com)
Rumors are true. Nintendo is gearing up to launch the SNES Classic, a miniaturized version of the glorious original Super Nintendo Entertainment System. The console will include 21 games when it launches September 29. A report adds: Among the big surprises: a never-before released Star Fox 2 is in the mix. Here's the full list of games: Super Mario World, Super Mario Kart, The Legend of Zelda: A Link to the Past, F-Zero, Super Metroid, Super Street Fighter II Turbo: Hyper Fighting, Super Punch Out, Super Castlevania IV, Donkey Kong Country, Mega Man X, Kirby Super Star, Final Fantasy III, Kirby's Dream Course, Star Fox, Super Mario World 2: Yoshi's Island, Super Mario RPG: Legend of the Seven Stars, Contra III: The Alien Wars, Secret of Mana, EarthBound, and Super Ghouls 'n Ghosts. It will retail at a price point of $80.
...51 people will actually be able to get one, instead of the 50 that were able to get an NES Classic.
Not holding my breath.
The fun part about RetroPie is it automagically detects controllers on startup. Check out the Controllers section of their docs to see common examples.
I tend to leave my Pi on, so I have a few wired 360 controllers attached to it (power-a xbox 360 controllers, if you're curious). I find they work pretty well for NES, SNES, PS1, and Genesis (with minor remapping) games, and they are ergonomic enough that I don't get X-Box claw or any other hand cramps. They don't have quite the same feel as original controllers, but I find I'm able to do stuff like the Mock Ball and other timing-dependent tricks just fine. Of course, you could also just find some original controllers and get a USB adapter.
