In Snes9x 1.51 there is a motion-ripple effect that shouldn't be happening. Example below. at 9.25 onward, notice the wooden planks in the platforms, it looks like vertical 'scan lines' are appearing as the auto-scroll moves the screen. Anyone know what might be causing this?
Is that Snes9x 1.51 or the re-recording version (used for speed runs)? Could be a timing issue. Have you tried Snes9x 1.53 instead? That version fixes many timing-related issues older versions suffered from, could also be sprite limitations (as Snes games had funky issue when too much was going on on-screen). http://www.snes9x.com/phpbb3/viewtopic.php?f=8&t=4909
