I didn’t want to hijack hunterk’s thread, so I started my own. Here are my compiles of RetroArch for 64-bit Windows and for Android 4.2.2 or higher:

I will try to update weekly or when possible, also these are not official releases but development releases so expect some bugs.
These are all the cores available at the time that compiled successfully, though I may trim down the Android releases in the future since it’s a lot easier to remove unwanted cores from Windows but not Android.
