[quote=89311]The above may or may not work for other cores depending on the Makefile of the core you’re trying to bulid. It should be pretty similar though. Some cores don’t build with the “-j4″ option, some use a Makefile instead of Makefile.libretro, for example.
How would you know if it uses “-j4” or a Makefile??
Also the FCEUMM is an updated version of that found in Retropie, in this case would it just overwrite the old version?
