GPF has publically said that he is still working on his port of NeoPop the Neogeo Pocket Emulator for the Dreamcast and also this:
"It has sound, just missing DAC sfx (voice to sega start up on sonic , Metal Slug voices) at least thats what iv been told by some beta testers."
Its good to hear its still being worked on and we wish Troy the best of luck with it.
