Help with N64 Rips

Well, I've decided to start the long arch of ripping a lot of enemies from the 3Desk sprites of Yoshi's Story.

But there's one problem, is there a way to get rid of backgrounds and such to make it easier on me? If so, could anyone help me.

I use Project64.

What you use is partially just one file. Not a folder. So it would be most probably be hard to rip up the background

Not sure which you can get, but I've heard there is a graphics plugin that rips textures directly from the ROM.
That would be useful for this, as the sprites (although prerendered) will probably be stored in textures.

Which means they're pretty much useless if you do rip them. Unless you decide to make a 3-D game.

Maybe it was unclear, but I meant that the sprites themselves are stored as a texture on a flat 3D model. This is shown on the course select menu (the flat sprites rotate left and right) I know New Super Mario Bros does this for one enemy. I once thought I had found the data for question block and brick block graphics, but it was just the textures for the Micro-Goomba (which disguises itself as blocks).

Isn't NSMB just 3-D styled and not actually 3-D though?

NSMB uses both 4BPP graphics for objects and some enemies, as well as 3D models for larger enemies, special objects, and the plumber duo.

And how do you know this?
And where are the 4BPP graphics stored? All I've found is the HUD used on the map screen, some enemy textures like Micro Goomba blocks, and some mushroom platforms that for whatever reason are stored as 3D models (but the platform is a texture - maybe this is used for the tilting mushroom platforms?)

So there's virtually no way to rip them besides the slow paint process?
