    Hey guys, inside one of the ROMs I found a file named signature.ctr
    Maybe this is the signature which is used to create a legit ROMs? This file can be useful?

    I highly doubt it, but stranger things have happened. Is it in any other game? Also, which game?

    Don't get your hopes up at all.
    It's very likely just an ECDSA (Or whatever signing method is used) signature for some files stored in the ROM - Possibly the main executeable. So the idea being if you modify the executable so that it doesn't match the signature (Or vice versa) it would fail to load.

    Basically, it's probably just an additional level of security and probably amounts to nothing to aid in reverse engineering or learn anything new.
