So I was looking at the VGA registers the other day and I thought, hey why isn't a 640x400x256 color mode possible? I'm talking about a standard VGA, non-VESA, Of course it would have to be unchained (aka mode X), but you could get 4 planes of 64,000 bytes each, of course you would only get one page because it would fill up all 256k on the card, but the same is true for mode 13h. I doubt monitors would have trouble with it because 640x400 isn't that strange of a resolution.
So I spent some time mucking around with registers in an emulator and I sorta got something, but the aspect ratio was looking weird, maybe just an emulator thing. Anyways before I try this on real hardware and potentially blow up a monitor or VGA card I thought I'd ask if anyone has done it before? Do you have register values? Has this been done in a production game?
