Intellivision emu from Kyle Davis rising from the murky depths after 3 years, there is of course a little you should know:

Known issues in this release...

• I still haven't shaken all the bugs out of the audio system since the port from C#, so the audio is still a little shaky.
  
• There are still a few graphical glitches in some games.
  
• ECS and Intellivoice support are not yet enabled.
