Looks like it is time for another classic for the 2600 to be updated. Omegamatrix has begun working on a new version of Circus Atari for the system. There is no playable demo yet but you can check things out here: Circus Atari Age 2600. He's been inspired by the original game to create this new and updated 2600 version. So, far, I think this looks very good!

Fantastic news indeed.. 
I like the looks of the game. The 2600 was a fun game.
Great news, I loved Circus Atari, and it was one of the first games I bought when I got a 2600 a few years back. Looking forward to seeing the revamped version.
Looks brilliant - I love the gameplay of the original but even I find the square balloons a bit ugly - if the gameplay remains intact I'll be interested.....
