Real, UNIQUE colors, ie not just darker/lighter shades of the same color? If so, that sounds like a way neat trick that I don't think I ever saw anyone use!Crazyace said:you can set the pallette for BG1 to provide 4 extra bits of colour info, giving a 4096 colour screen.
Realistically, how many color regs could you realistically change with HDMA anyway? As I recall from reading emulator specs lists, there aren't that many DMA "slots" per scanline, and doesn't HDMA only work outside the graphics area of the screen? That would mean you couldn't get more than 256 colors per line (assuming no other trickery), though you could change at least some of those 256 colors on a per-line basis...without any HDMA trickery
I don't remember seeing any game that used this extensively though, prolly because it isn't that useful. There was some fog-type stuff in the horizontal scrolling sections of Axelay that seemed to be done with raster fiddling, but it was much more common in Amiga games where you had more power to do raster stuff as well as fewer color registers to begin with...
Biggest problem with SNES tho, even bigger than slowdowns, was the god-DAMNED sprite flicker problem. Very few games managed lots of sprites without also having extensive flickering...
