This command converts the specified address to a physical address, then writes the physical address and size to the [[GPU]] registers at 0x1EF018E0. This buffer contains [[GPU_Commands|GPU commands]].

The associated buffer address must not be <= to the main buffer address, thus the associated buffer address must not be zero as well. When the bufX address is zero, processing for the bufX parameters is skipped.

Some color formats seem to require specific input / output sizes when performing a display transfer, doing an RGB5A1->RGBA4 display transfer would never fire the PPF interrupt with a 32x32 buffer, increasing the buffer to 128x128 made it fire correctly.
