Except for that is doesn't work like that. You can't access all 61 (not 64) colors in a single *tile* like that. It's 16colors per tile. The SNES mode is 256 colors per tile. The PC has no tiles and it's just 256 colors straight bitmap. Plus I doubt you'd get even a decent play rate at 320 wide rendering area. More like 256 pixel window with double wide pixels for a blowup 128 pixels wide window. Like Duke 3D on the Genesis' did. Duke 3D took advantage of the fact that the pixels were double wide and the video out of the Genesis was/is blurry (except for RGB and svideo Genesis systems). You can get 155 *fixed* pseudo colors that way. And they are definitely fixed They just won't be 'pseudo' colors on setups of RGB and svideo systems.
