New on emulator megadrive?

Hi, has many time wich i don't see BLACKAURA, there are possibile of see at the end of this year, a official new version of his emulator of genesis?
The status of this emu?
I read wich speed is good, only small problem with sound, i want know if this emu support the SIX button :| for me is more important the support of six button, why love play the street fighter series and mortal kombat series, on megadrive, for me are the versions more beauty.
Excuse me for me questions =) don't kill me ehheeh.
