Ripping Questions

[Ultimecia]

Is it possible to change the background color once the background layers are disabled using any SNES emulator? I'm in a bit of a bind, the sprite I'm trying to rip's outline is the same color as the background.

Anybody?

I got the same problem here, when I was ripping Batman Return's bosses. And that's why I didn't even talked about ripping Batman himself. Most of emulators seems to follow some default color or index linked to the regular background layer.
Which emulator you use?
