Two days ago I commited a major Oolong update. Please check out the Oolong Engine blog at
I updated the memory manager, the math library, upgraded to the latest POWERVR POD format and added to each example VBO support. Please also note that in previous updates a new memory manager was added, the VFP math library was added and a bunch of smaller changes were done as well.
The things on my list are: looking into the sound manager ... it seems like the current version allocates memory in the frame and adding the DOOM III level format as a game format. Obviously zip support would be nice as well ... let's see how far I get.
