Emulation is a lot better, tested in 3DSX and CIA. I haven't seen the framerate dip below 99% yet, but it's really hard to tell that Pac-Man is closing his mouth (that could just be due to the LCD itself). Sound is a lot better, but there's still some quirks here and there (Pac-Man's intro music sounds like chimey bells, for example, which "enable higher frequencies" off seems to fix?). Is there a way to use the d-pad instead of the circle pad for games? It's working fine in the menus, but I can't get it to work in any games. Obviously, you would need the circle pad for the 5200's analogue controls, but it's literally killing me in these 8-bit games. Same here, I just tested on Centipede.
