Ripping Questions

[Solink]

I doubt that the tool I'm about to ask about exists, but someone on another forum who's started doing genesis rips asked about it, so I'm testing his luck, as well as my own: Is there such a tool for genesis emulators with layer control, that can change the color of the backgrounds one the layers are disabled, making sprites with the same shade as the background color easier to rip?
Also, is there a tile program that works with genesis emulators?

Dazz(from this forum) did one.
You can ask him and he will maybe give it to you
