Unfortunately, nothing much have happened since the move to Github. I don't own a working Mac anymore, and some of the libraries used in OE are not simple to get working on Windows.
I haven't considered crowdfunding at all. MSR used to accept Paypal donations, but as we haven't really progressed any it doesn't feel right.
But please, stick around. I have some big ideas for the future of OpenEmulator, but I need to write some prototype code first before I feel ready to present it.
