Photoshop :: Animated Smoke/Flames Separated By Frames?

Have an animated fire/smoke effect. But I need to have each frame as individual images. I'm inputting it into a game that compiles the images together into an animation in-game.

I have found lots of smoke and flame tutorials, but have not found any on how to make all the frames I would need for a smooth looping effect. If possible, I believe there are small little programs which can create animated fire/smoke for you, and then break it down by frame. But I have no clue what programs can do this. My main concern is to make sure the flames/smoke are as clean as possible in order to be able to make an alpha channel to provide me with transparencies around the effect.

So if anyone knows of a tutorial showing me how to create smoke divided by different frames (20+ or more so it is nice and smooth), please let me know. Of course, if you are willing to provide a quickie tutorial, then even better.

Or if someone has a name of a small program I can use that will create fire/smoke for me, then separate it by frame and save them,
