I am extremely excited to move past the limitations of the Dream, and use real animations on the Nexus One. (if there was sound, I'd wet my pants)
I've made an animation with the same dimensions as yours, and I exported each frame to png. I kept your naming convention, started with boot_00003, and used the same number of files, split into 2 folders. What else do I need to get it to work? Would using Stericson's utility to sign the zip work? (The one he made for the Dream)
I have a few more questions, but if someone could answer the above, I can probably figure the rest out on my own.
Thank you, Prash, great work.
