Copyright laws allow you to have a backup of any media.
Downloading a rom of a game is legal if you already have the physical game. So, dumping the .sav and downloading the rom, is completely legal.No, copyright law allows YOU to MAKE a backup copy. Downloading somebody else's is not making it.

Under section 117, you or someone you authorize may make a copy of an original computer program if:
* the new copy is being made for archival (i.e., backup) purposes only;
* you are the legal owner of the copy; and
* any copy made for archival purposes is either destroyed, or transferred with the original copy, once the original copy is sold, given away, or otherwise transferred.

Isn't it legal to copy computer and video games as a backup as long as you own a legitimate copy?
U.S. Copyright laws permit making a "backup" copy of computer programs for archival purposes. However, the right to make backup copies of computer programs for archival purposes, as embodied in 17 U.S.C. Section 117(2), does not in any way authorize the owner of a copy of a video or computer game to post or download a copy of that game to or from the Internet or make such copy available to other people for their use. Section 117(2) only gives the owner of the copy a right to make an archival copy of the actual copy that he/she legally possesses, not to make a copy of the ROM that someone else legally possesses, nor to post an archival copy of his/her original copy for distribution. The law clearly does NOT provide any right to sell "backup" copies. In fact, Section 117 is quite explicit in stating that any archival copy prepared under Section 117(2) can only be transferred to another person if, and only if: A) The original copy is also transferred, and only with the authorization of the copyright owner, and B) The transfer is part of the sale of all rights in the program.
