a GEN emulator?

Hello, I have finally found 'shining in the darkness' for the Sega. I played this when I was a kid and want to play it again.It's a GEN file and I have no idea what kind of emulator to use. I have VBA(visual boy advance) & R4 DS.
I assume however, that either of these won't play it.
Any help would be wonderful, thank you!

So, it's a Genesis rom?Then, you can most likely play it on jenesisDS, which is a Sega Genesis emulator for the DS.http://downloads.exophase.com/302/jenesisds-v074/Or for computer, then use Gen. - http://www.emulator-zone.com/doc.php/genesis/gens.html

If it is a Genesis/Mega Drive game, jenesisDS may be able to play it.http://filetrip.net/file.php?id=4562

Awesome, very fast replies!
I have it downloaded and going to try it this afternoon!
THANK YOU!

You're welcome. :)They should work fine with the emulators.
