hard to say, since theres only a video floating around (the Beta testers just wont say anything). It loads directly from the flashcart, so its very fast (all emus for the gba are fast, because the acces time ist very low). I dont think it´ll be portable to the GP32, but i dont know anything about coding, so we should wait and see how itll run on GBA and then sse, if it woulb be worth porting (and find someone who would do it)
