Comments on Preliminary use of 3b+ for emulation

Tried the pi 3b+ using the beta stretch retropie image.(used win32diskimager).   Have heatsinks on but haven't put a fan yet.  

Atari, nes, psone performance was acceptable on tested games.   Tried a few n64 games, Mario and Zelda, but there were a few minor dips, I wouldn't mind the dips if they didn't also affect the music, but they do so I do mind.    Might be solvable with post-beta retropie, or overclocking or putting a fan on the pi.    But for now I think, at least for emulation of stuff near n64, it may be easiest to use a nextgen model which may be available in a year or two.

How To Pair Xbox One Bluetooth Controller With RetroPie

Comment:
Did not mess with command line.

After updating 1708 model xbox one controller(model number behind batteries on back of controller) on windows 10 free xbox accessories app, tried directly connecting the xbox one controller with micro usb cable and it was detected instantly on latest retropie image.   Works with cable easy as pie.

  Setting up the Bluetooth does not appear to be possible just using the same controller without a keyboard, though it appeared to detect it in Bluetooth after disconnecting, process couldn't complete since I had to reconnect to confirm detection, and reconnecting took it out of Bluetooth mode.

Given that it appears to detect it, I suspect with a spare controller connected through usb, it should be possible to connect another xbox one model 1708, and probably later versions, via Bluetooth without messing with command line.   That is on latest version of retropie on pi 3b+ as of April 2018.
