Hex Edit question

[Meepo]

I recently downloaded Hex-Editor, since in my FE7 run serra died and I need to bring her back to life. If any one knows the code-thing that I have to change to do this, it'd be much appreciated.

That's something you do in regards to the game's memory, not in a hex editor.

Open up the rom in VBA, and go Tools --> Debug --> Memory Viewer

...and of course I forget what section you want to go to, Blazer should show up any minute, he does this a lot more than I do, but essentially what you're doing is finding their HP number and changing it from 0 to a non-0 positive number and removing their "death" tag(note: this will only work if you have not engaged in a battle since her death, if not, you'll have to restart).

You need to do this in a memory viewer on the actual emulator. Watch Blazer's YouTube tutorial on memory hacking

Well you could edit the save but it's checksum protected. The bits are also very tedious. I used a Nintendo DS Action Replay to hack my official FE& (U) cart's save data so dealing with the checksum is definitely not an issue, but if you can I recommend just copying and pasting one of your characters in the WRAM and editing the copy to be Serra. Serra's original data is probably gone by now.
