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.

Doesn't matter. At or over 2/3 jewish either way.
The basic distance-length idea was on surface. LZ were just first to write some crappy paper on it. Nothing original. Tomorrow some jews will write paper on ass wiping.
