I compiled up a steaming bag of horse shit otherwise known at OpenEmu Experimental. The build date is 05.18.2015. I think the newest experimental build offered on OpenEmu's site is from October 2014. You can download my build form here.
I also built up a fresh plate of the most excellent Sony PSP emulator PPSSPP. This build is a little different than the one offered on the official PPSSPP site. To run this build you do not need to install Homebrew from the command line, but you only need to have the SDL2.framework in /Library/Frameworks. You can download my build from here.
