QuoteIs it likely to be as easy as finding those 4 values relatively close together in the ROM with a simple hex editor?
Quote from: Axiphel on June 28, 2016, 04:11:46 PMJust saw this on the newest releases. I see it needs a headered rom. Aren't headers completely useless and from a time long since passed? I don't think I've ever had a rom that came headered.
Quote from: zhade on June 28, 2016, 04:40:03 PMAre you sure you posted in the right thread ? I have no clue what you are talking about.. altho I think most of the roms available on the net do are headered, I dont really see the point of distributing non-headered roms.. Anyway, since headers are disposable, I guess you could just add some bytes to your ROM in order to make it work with a patch that requires a headered rom, then you could remove the "dummy" header
Quote from: Axiphel on June 28, 2016, 04:47:41 PMThis, which is what this thread is about, requires a headered rom. I've literally never gotten a rom that comes with a header and I've read that there is no point to a header anyway. Adding or removing a header is trivial. I was just wondering what the point for it is.
