are there any way to rip game like metal slug directly from the files??

Hi guys!new! are there any way to rip game like metal slug directly from the files?? as oppose to rip it "manually" frame by frame with an emulator?? the reason i ask this is that first i need a lot of sprites from a game for a project, the second is that judging the fact that i can see there a abundant amount of sprites sheets for example, metal slug and the sprites are arranged into separate parts, explosion apart, various of body parts apart, i can't help but thinking there could be a way to directly extract the data from the files themselves instead of ripping it manually...

hope someone can pass on some view into this

thanks!!
