Is it anymore safe to use a dumped header then a shared header?
Well so far, Nintendo has done nothing about players using the same header online. So they may or may not ever do anyhting.
So to be safe, you can use your own game header so that only one of this header is online, no duplicates. Once you got it set up, you'll be a bit safer from bans in the future and wont have to start a save over to use a different header.
Though Nintendo may still detect something odd about Gateway users and injected headers. Just play it safe to be sure.
you can use any header "generally" without modification as long as its the same size or bigger than the game your using it on and matches in terms of card1 or card2, (hence my MGS works on most games as its card1 like 99% of games, and its a 4GB game.....the biggest size available atm)
but some games also act a bit once you factor in gateway rom patcher automatically adjusting the card size and card type.....the only left over variable that needs tweaking is the card manufacturer........as long as your using gateway rom patcher, the only thing you will ever need to do is try the different card manufacturers untill you get the right one
......people are over complicating this, its not hard
Oh that's new to me. I didn't know that the game size CAN be bigger and still work. It's no wonder the MGS header works for all, I've been wondering why.
So if I use a 4 GB game header of my own, it will automatically work for all games just like MGS huh.
I guess editing is only needed, if you don't have any 4 GB games, and only want to stick to dedicating one game for headers.
