I'm glad that I looked at this thread, didn't think hard enough to realize that NAND in emuMMC is actually on the SD card and now I have more free space to install games after moving stuff to NAND.
Perhaps I'm missing something, but how does moving to emuMMC "internal storage" create more space? It doesn't increase the size of your SD card. If you install a 10GB game to your emuMMC "internal storage" it still takes up 10GB on your SD card. How does using a different location on the SD card create more space on the SD card? I only see problems down the road as mikefor20 stated, if the emuMMC "internal storage" runs out of space.
