So I just spent a while looking at things and making it run a little more nicely, the problem with most cores right now is that they are C++ so they would fail for now. Anyways, after doing some small cleanup here are both fceumm and snes9x2010 from the current commits:

These 2 elfs will start up quickly, have audio working properly, on game starts there are no more random pixels before game picture or audio beeps/scratches, pausing the game and going back to the menu now works properly as well.
Overall I am shocked to see how well it already runs now and I hope more can be added soon
