is currently working on a SEGA Genesis emulator called Genesis4iPhone. A BETA is now available to testers, with a full release planned in the near future. If you are not a BETA tester and would like to be, the best way to become one is go to ZodTTD.com
, register in the Forums, and donate to his project.
To quote: As you can see, things are shaping up nicely so a public release will be on...
