Just gonna jump in on that controller question:

I set up my RetroPie about a week ago, and I started using an old wired xbox controller I had. It worked fairly well, and did everything it had to.

However, I also recently purchased some USB N64 controllers to use instead, as I thought that they would be more authentic, and feel more retro.

I HIGHLY reccomend using N64 controllers – they work a treat. I mostly emulate SNES games, so while a SNES controller would seem like an obvious choice, the N64 controller works I think much better.

For starters, the N64 controller has a D-pad and analog stick, but unlike an xbox controller, both work to control the SNES D-pad, even though I’ve configured the analog stick as an analog stick.

The Z trigger I’ve set to select, which works well, and whilst the N64 has no X or Y buttons, 2 of the C buttons are automatically used as x and y when playing SNES games.

There is no better alternative in my mind.

There is a large range of choice of N64 controllers out there, personally I went for some fairly cheap ones, but they work great and I reccomend them:

Sorry for the rant about controllers, just thought I’d let you know how great I think these are xD
