> What is a header? What is dumping? How do you save a header? What game would have the same header as SoM?
Dumping is the same as making a backup. It's where you put your game cartridge in the backup unit and transfer a copy of the game to your PC.
If you dump a game on a recent backup unit you'll get a header tacked on to the front of the ROM image. The header is the first 512 bytes of dumped file. If you look at the first few bytes of a Game Doctor dumped game you'll see it has "GAME DOCTOR SF 3" there.
To save a header you get a hex editor, like Hex Workshop, and save the first 512 bytes of the file you backed up on your Game Doctor to a new file.
There isn't much info on Game Doctor headers but you can find some on SMC headers in Disk Dude's excellent Snes Kart document.
If this is too much for you then just try the general approach of using insnest to convert smc roms to Game Doctor format roms. It works most of the time.
