It's a good emulator but if I'm not going to donate the first time you ask me, I will sure as heck NEVER donate if you ask me like some desperate virus shoving popups in my face. I had been tempted to donate before it started doing this. I've used much better emulators that don't do that. It's pretty low of this emulator to force a pop up that forces itself up for a good lengthy period of time trying to beg for donations every single time you open the thing. Now, however, I've had to switch to a different emulator. Don't get me wrong, I used to love project64.
