Are there any open source sprite format?

PNG just plainly sucks. I has no support for animations, timing or delta compression and sequence names. Also, PNG is slow at random access (you have to decompress image before use). Proprietary formats (like Diablo 2 DCC) are much better, but highly specialized for their games: some have no true color, other have no directions.

Are you retarded op?

>not using even the most basic engines which support pre-loading sprites, SINCE EVERY FUCKING FORMAT HAS TO BE IN UNCOMPRESSED RGB OR SOME SUCH NONSENSE BEFORE BEING RENDERED
