The Apollo Emulator is actually quite good. It boots a lot of games. I presume this to be a core problem? Am I right? And you only have an audio plugin - are there any plans to update your graphics plugin???
8MB expansion pak is implemented in the emulator itself. As far as my graphics plugin goes, I am getting there... slowly but surely. I've been slowed down with some health issues to take care of. I hope to get back to it soon.
