I'm making a video codec that uses Color Cell Compression, the predecessor of S3TC. A clip can have 16 colors, and each 4x4-pixel block usea two of them. I aim to play FMV on Mega Drive and Game Boy Advance.

It codes 256x144 pixel 12 fps animation at 25 to 42 kB/s depending on motion. Live action is 62.5 kB/s. Fits Sega CD bitrate, not so much Genesis or GBA cartridge yet. I still see room for byte savings.
