General Hex Question

Thanks Nattak. This is a long process to learn. There is a ton of code to put in just to make a character appear on the screen lol.

Is there a reason why I should use a headered rom?

There is no reason one way or the other, the header just gets in the way when event hacking, so I would erase the header to make it easier to put in the right addresses, and so that the event dump addresses match, without having to factor in and worry about the +200 to everything. There's an option to delete the header in the hex editor. There is a reason to have a header sometimes, a lot of patches and editors require the ROM to be headered, so just be sure and re-add the header with a tool like SNESTool if you are going to apply a patch that requires a header.
