OK so I looked at your ani and this is what I suggest
First the only folders that should be in the zip is part 1, part 2, and the desc.txt
When I opened your zip these files were inside two other folders
Second change the PNG numbers to start at...
You need a .txt file to let the phone know what part to run when and at what fps but I can't remember the code, my suggestion is to find your stock ani and look inside it for this

From what I've found you will have to edit the pngs in the Rosie.apk file.....run them through Photoshop and recolor them.

I've tried running .gif boot animations before with no luck, not 100% sure it will work...which sucks cuz you're right, it would be waaaaay easier than a thousand sequential images.....
Extract all the files from the zip on your CPU.....hilight all the files and right click, select archive, when the window appears select zip, and from the drop menu select store....mine was doing this also if I just zip it.....hope this isn't too ...
