Demoscene ROM rendering errors with perspective correction.

[LivelyZephyrs]

As the title says. Some Mode 7 scenes don't render correctly with perspective correction.

elix-smashit-pal:
Perspective Correction ON, incorrect rendering

Perspective Correction OFF, correct rendering

2.68 MHz Demo:
(Not pictured here, but with perspective correction ON, the Mode 7 bugs out some)

hello.sfc by Binary Counter:
Perspective Correction ON, incorrect rendering

Perspective Correction OFF, correct rendering

The ROMs for these demos, zipped up:

Demos are mostly automatic, 2.68 MHz Demo being the exception, and asking for occasional B button presses.

Thanks for collecting those. Just some quick first impression, strictly from the screen shots and descriptions:
"hello" won't work with 'on', as is is not a simple perspective, but more like Terranigma. But I like having it for when I work on 'auto'.
"elix-smashit" is currently not expected to work with 'on', but when I try out improvements it will be a test-case that I didn't have before, with a sharp change in direction.
"2.68 MHz" I'll have to see

Thanks, reuploaded it to GitHub for archiving: SNES Demos.zip
