If it's easily identifiable, then wouldn't simply posting it put the leaker at risk?

Sorry if I seem pushy, I just really want to screw around with that palette debug (I'm easily amused).

EDIT: To clarify, if the ROM is identifiable (assuming you mean it as in the leaker is the only one who had access to the ROM or whatever), then you've described all the stuff that makes the ROM identifiable. Hey, I'm sure there's something crucial I'm missing, but...
