//TODO
//libsnes needs to be modified to support multiple instances - THIS IS NECESSARY - or else loading one game and then another breaks things
//rename snes.dll so nobody thinks it's a stock snes.dll (we'll be editing it substantially at some point)
// edit - this is a lot of work
//wrap dll code around some kind of library-accessing interface so that it doesnt malfunction if the dll is unavailable
