Shouldn’t be performance issues with the NES emulator. Complete guess but the usb hub could be feeding power back to the Pi and causing problems, check it’s on the list of verified hubs here: http://elinux.org/RPi_Powered_USB_Hubs

This is the usb hub I have been using for a year and a half with no issues: https://www.modmypi.com/New-Link-4-Port-USB-Hub-(USB-2.0-with-Mains-Adaptor)
