Anyone can DMCA anything for anything. The relevant factor is how likely different providers in the chain are to respond drastically to bullshit requests.
For instance if I sent a DMCA to HN insisting that your comment violated my copyright, they'd probably ignore it, or ban my account.
Nintendo doesn't have a fucking clue what you have locally until you publish it for the world to see. Until you host it somewhere remote, there is nothing to DMCA.
