PocketMatrix

Like I said, you can still implement this yourself thanks to getbuffer/releasebuffer. It's actually not that difficult and the performance hit may not affect your game all that much. Also, the performance hit somewhat nullifies it self due to the reduced memory traffic.

You've other options as well though. Reduce the framerate of your graphics, introduce a dynamic caching mechanism (Sprite Pool as I like to call it) reduce the size of the graphics (As in width/height) etc.
