Hi,

I'm a bit confused about how memory usage works.
Ok, I understand you have main RAM, VRAM and SRAM. I also understand you
can't get at the VRAM or SRAM directly.

My problem is with the following: Say you have 1/2Mb of textures and 1/2Mb
of sound data. These would fit into VRAM and SRAM respectively with no need
to keep copies in main memory. However, as I understand it, you have to
upload them to main memory and then have your code copy them to VRAM/SRAM.
So that's 1Mb of main memory taken up, used only to store (very) temporary
copies of your data. This seems like a bit of a waste of a pretty scarce
resource.

Have I gone wrong somewhere, or is that right?

Thanks in advance,

Mike
