SubjectNES emulation issue new Reply to this message

Hi,
I've noticed some weird graphical artifacts with NES emulation (that happen with any and all emulators I tried - Nestopia, FCEUltra, VisualNES to name a few).
This specifix issue I noticed with Super Mario Bros 3, but I saw it happen in other games with scrolling game screens. Basically, when you move to the right or the left, so that the screen scrolls, you get narrow column bars on both sides of the screen that display wrong colors or completely wrong sprites.
In SMB3, for example, when you walk to the right (very first stage) the right side of the screen has a vertical bar several pixels wide that displays bad colors for the sky, pipes, and blocks as they scroll into view.
I don't remember this artifact being in the game on the NES, but that was a long time ago... or perhaps it gets hidden somehow by the TV?

Yep, it was hidden by the TV.

Just as I thought. So, is there any NES emulator around that has a "clip to TV viewable viewport" function? I find those artifacts really distracting...

I think VirtuaNES and NEStopia allow you to define how many pixels you want to clip off the side. Can't check right now (stuck on my powerbook). Worth a peek-a-boo

Nestopia does, and FCE Ultra has a 'clip left and right sides' option that is quite handy.
