Yeah, Tree Skip has been tested to work on all platforms. Hold the analog stick at about 4:30 ("o'clock"), and you'll get it eventually. Keyboard also works, but most people use a controller.

Nostalgia is the biggest reason for me. Also, friendly competition is fun.

I can do any of the Genesis games. Quackshot would obviously be my first choice and after that, maybe WoI and CoI, in that order. I can bring my Mega Everdrive if needed.
