Any Tips on Ripping Final Fight CD sprites?

[EpicOcelotMan]

Do you guys have any tips on ripping sprites from Final Fight CD? I'm trying to rip some sprites, specifically Poison/Roxy, and possibly even Sodom, aka Katana. Trouble is, the background tends to share partial palettes with the sprites, especially Poison/Roxy's.

I'm using Fusion as an emulator, if that helps
