I want to do this with Wild ARMs 2. I'm just wondering how you would do it. Is an emulator required (I do have a PS1, and the game would be a legitimate copy)? Do some allow removal of layers like "ZSNES" and "VirtualBoy Advance"?

BTW, if this is not an appropriate subject for this board, I will drop this. If it's an okay subject, then how would I do it? 

No one knows how?

There is a way to use an emulator an rip assets out. Its done by a special graphics plugin. I know you can get 3-d model with it, but I'm not sure about sprites, although considering thats its sitting in VRAM I don't see why it wouldn't work.

I can't remember its name or anything, so you'll have to google that shit.

If worse comes to worse, try and find out if the sprites have been ripped by someone else. Or just use screenshots.

If you have the .iso you would likely need some rom hacking skills to extract the images from the media.

The alternative is simply to photoshop the images out of the backgrounds yourself.

Either way you're likely looking at a fair bit of work. 

Since I don't plan on pirating, I could likely get the ISO from the discs themselves (not to upload).
