comment Skipping glReadPixels and reading iPhone's “VRAM” directly
Cool. What do you think about reading piecewise into a GLubyte buffer with glReadPixels... then dump the buffer to disk on another thread? The buffer would be alloc'd once and re-used. Suppose I might need two buffers since I'll be filling one while dumping the contents of the other to disk.

raw FBO dumps sound interesting. Formatting the data later will work. How would one save the contents of an FBO to disk?

Simulator won't work for this unfortunately.

glReadPixels is the bottleneck when trying to copy the entire screen. If I copy part of the screen then AVAssetWriter's appendPixelBuffer is the bottleneck. Now I'm thinking about drawing directly into a framebuffer-attachable image.

Cool. I do something similar (see edit #2 to the question). In my update function I check the "coinsActive" bitset if(coinsActive) before I loop over maxNumCoins and update. This way I completely avoid the loop if zero coins are active.

I'm just curious about older games 8-)

Good point. I'm really curious about dynamically allocated collections vs statically allocated collections
