Description
The VDP (Video Display Processor, 315-5113) is the video processor of the MegaDrive.
It's an evolution of the Master System VDP (which is an evolution of the TMS9918a video chip, see [1] for information about the Master System VDP).
It is backward compatible with the Master System one (MODE IV) but this section will only talk about the MODE V (MegaDrive mode).
Display Specification
The VDP think by CELL (a 8x8 pixel pattern).
It can output a 32x28 CELL image (256x224 pixels) or an 40x28 (320x224 pixels) one.
In PAL mode it can also output an 32x30 (256x240 pixels) or 40x30 (320x240 pixels) image.
