The decreased value in VBLANK should remove the black border at the bottom by shifting everything down (I think this is the border you're referring to). I didn't touch HBLANK or HACTIVE yet since there wasn't any guidelines in the documentation. Currently they're at the default values, but I do notice that the image is shifted to the right a bit. I suppose I could try to center it horizontally as well. Although it says that VBLANK should start no earlier than line 22(NTSC), I am seeing a raster or two of VBI data at the top of the image and it is slightly lower now than my tv's broadcast input. I might try increasing VBLANK by 1 or 2 to make this perfect.
