Notes on main memory (display fifo) mode

The display fifo is at this point not emulated accurately in respect to the hardware. Instead what happens in the emulator is the following:

When display fifo mode is enabled in DISPCNT, at the beginning of a hblank the GPU sends a request to the MMU checking for a properly set up DMA channel (word count=4, repeat on, fixed dest, etc). If no such channel is found, nothing is done. If such a channel is found the MMU will return the DMA source address to the GPU, which in turn copies the data from that address (offset by the current scanline) to the virtual screen.

There's no delay until the next frame starts, as would be the case on a real DS.
