// for VRAM display mode, VRAM must be mapped to LCDC

// FIFO display mode:
// * the 'FIFO' is a circular buffer of 32 bytes (16 pixels)
// * the buffer doesn't get empty, the display controller keeps reading from it
// -> if it isn't updated, the contents will be repeated every 16 pixels
// * the write pointer is incremented when writing to the higher 16 bits of the FIFO register (0x04000068)
// * the write pointer is reset upon VBlank
// * FIFO DMA (mode 4) is triggered every 8 pixels. start bit is cleared upon VBlank.
//
// sprite blending rules
// * destination must be selected as 2nd target
// * sprite must be semitransparent or bitmap sprite
