VBA

I'd say it is. Check the "Tools" menu and the various "Viewer"s.

 

Get used to it. Clean pictures consist of tiles. I make images like this. With frame skip set to 0, I take a screenshot of where an animation of Tails starts. Then I save each oam tile. So I may have something like s01.bmp for the screenshot and tiles such as t01a, t01b, etc. Then use the frame advance to go forward one frame. Repeat about 46 times and you're done. Remember that VBA has a bug when saving images. It says "open" instead of "save" and as a result, it overwrites files by default if you give the name of an existing file. So be sure not to lose count. Then I combine all the oam tiles to make full sprites. The screenshots are used for offsets and aligning as I build frames for the animation. It doesn't get much easier than that.
