Strangely... the dev made it free. Which is kinda lame for me who bought the very first version that came out and paid $6.00. And even then, the service was on par. Well, if anyone ever wanted it, here it is.
You have to download the ROMs(games) to play the emulator. Most likely, there will be a converting process required for most ROMs. So it's best to have a PC, and google some instructions on how to get all this going.
If you know what to do and just need this free emulator, here it is.
