Ok thanks.because scene releases are considered "clean", the header info isnt actually part of the rom normally, the gateway dumper strips the header from the chip and injects it into the rom file so it can use the information to connect online.........so really the dumps with header info are technically bad dumps
also if nintendo ever does block shared header data the uploader could potentially be blocking their own cart so a bunch of random people can use their header
And can I patch the rom with a random header? Or do I need a "legit" header from a retail game?
