Why don't you ask in the "development" section of the ZSNES board?  |

I seem to recall reading that it was only available as a 3D mode, but I might not remember correctly. Been awhile since I studied bitplane modes.

Far as I'm aware, it doesn't double the screen's height - just the width. And at that, it's not perfect.
Basically, what happens is you store something as double-width in VRAM, and instead of actually doubling the width of the screen, it just alternates displaying adjacent pixels really really fast. Thus the reason you don't see it used very often - it requires twice as much VRAM as normal display, and you have just as much VRAM to go around as you had before.
As far as activating it, I'm honestly not sure. Sorry. |

How exactly is it accessed and why is it barely used at all? (Only games I know of would be Secret of Mana and Tales of Phantasia use it infrequently and Seiken Densetsu 3 use it a lot.) Does it automatically "double-size" tiles and sprites on screen like it seems to (I'd think SD3 would run friggin' slow if it weren't automatic.)
You could get a lot more out of some games if it could be figured out more... |
