I'm not nitpicking at all. "Mode 7" as you claim people understand it is fundamentally HDMA + Mode 7. The OP's original question is if "Mode 7" could be emulated on other hardware of the day? In other words, could other consoles of the day provide HDMA (read per scanline effects) and Mode 7? The short is answer is no. While per scanline facilities where common, Mode 7 was only available to the SNES.

Of course with software any effect can be generated (obeying hardware restrictions), however it could be time prohibitive. For instance, a Gameboy could do "Mode 7", but the game would run at 0.01FPS.

However modern hardware is much more powerful than old stuff, and can fully emulate Mode 7 in hardware. My point is that a properly configured graphics pipeline could do Mode 7 on a GPU.

> Accuracy is not exactly relevant here.
Lookup tables operate on the principle of trading time for space, ie computation time for memory footprint of the table. Since the multiply registers tied to Mode 7 have at least 24-bit accuracy, I'm wondering if such a lookup circuit would be prohibitively large. I only know how to make basic multiply circuits, so I can't comment on this.

>That's planar scaling and rotation. There's no world transform, perspective transform, projection or anything of that sort in there.
Or in other words those matrices are set to identity, so if they were considered, they wouldn't affect the final transformation. Of course the SNES hardware doesn't keep track of this stuff, but my argument is that you can map SNES hardware onto modern hardware.

"Mode 7" as you claim most people understand it as is fundamentally a per scanline technique, as you yourself have acknowledged. Do you not see the similarities?

Are you retarded?
