PocketMatrix

I can't think of a single reason why you should target a game to run at 60fps. Those extra cycles would be put to much better use doing something else, like added effects.

By bitmap copying I was refering to the Windows function calls for bitmap copying. e.g. The CreateDIBSection stuff. I heard there was an equivalent on the PocketPC.

So you can buffer your graphics on a HBITMAP, and blit it to the screen. But would that method reach 60-70fps?

And how do you do page-flipping? (Did you mean page-flipping as in flipping the hardware screen address, or just double-buffering)

And what's the memory map of PocketPC?
Or does it vary from device to device..

Not using the fullscreen mode will only work for direct-access to the video memory devices such as the iPAQ.

Devices that use an intermediary buffer (E-125) might not be able to provide "windowed" mode. (But see GXSetViewport()).
