@connormalc Raspbian is just a linux distro with specific Raspberry Pi bits, for x86 hardware I'd install another distro which might be better supported on the PC. PIXEL is the name of the former desktop environment for Raspbian, I don't see how that would help you, maybe you meant NOOBS ?
I'd advise using bootcamp to try out Ubuntu - get the LTS 18.04 version - and install RetroPie on Ubuntu as explained in the Docs.
RetroPie does not run on Windows and while Emulationstation and most of the emulators run also on Windows, it would take some time to manually configure them to work together.
Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first
