A save research/discussion for Fire Emblem Echoes: Shadows of Valentia. Sole purpose to collect IDs for convenience. If you want to find hex IDs that are missing or in DLCs read @TildeHat's explanation below. Would appreciate if people contributed in the thread with the IDs that are missing ^^. I'll update as more information rolls in. My resource.

IMPORTANT IF YOU ADD BYTES TO YOUR FILE
If you just replaced bytes, then you're fine, disregard this. If you see your file size has changed after you edited it, then this applies to you.
Step 1: Changing the pointers. Go find the text string EDNID. There you'll see 5 pairs of bytes that aren't 0's. Should be from offset 0xC8 to 0xD9.
Step 2: Now if you added bytes to your files, these pointers should be incorrect. Why does it matter if it's incorrect? Well you'll lose some stuff like inventory and units so yeah. To remedy this problem you want to to find these text strings: TOPS, TINU, NART, IFER, and ILER. The first pair of bytes is the pointer to TOPS, second pair of bytes is the pointer to TINU, third pair of bytes is the pointer to NART, fourth pair of bytes is the pointer to IFER, and the fifth pair of bytes is the pointer to ILER. as shown in the picture as a reference.
Step 3: Copy the offset of the first letter of the text string and reverse it. So let's say it's located on offset 0x6887. You would just reverse it. The new offset would be 0x8768 which we will just remember.
Step 4: Now replace the bytes from step 1, the pointers, with the new offsets that we just reversed. So now I'm replacing 0x4367 by 0x8768. And to double check if it points correctly, just reverse the value and go to that offset.
Step 5: That's about it. Just apply the same step to the other pointers.

- The game's save file reuses the same file compression method as its previous ancestors, Awakening and Fates, so you could reuse @SciresM's FEAST again without any trouble.
- IDs (Character, Class, Weapons, Items) are 8 bytes long. Reasoning is it actually is a label calculated by using 2 polynomial hashes instead of a byte assigned by the game before which is explained by @TildeHat and there are pointers which you could use by simply reversing the bytes for the offset.
- Structure of the file should be a bit similar to Fates's so if you got some prior knowledge of Fate's structure this should be easy for you quote @Soaprman
Just some things I found that I think a lot of people are the most interested in editing.
To find your coins simply just convert the value that your game shows to hex and reverse it. EXP: 999 (0x03E7) Silver coins. Reversed Value: 0xE703. And just search with the reversed value.

I made a mistake, the orange F1 belongs with the green highlighting, the Skill Item in progress. The Byte after the item is the rank, 10 = 1 star, 20 = 2 start, etc.

For those of you who are curious about having pernament amiibos in your party, here are the amiibos (excluding Alm and Celica): https://drive.google.com/open?id=0B9HGNDRpe1v0azBITmt5TWRjelk . Follow the guide below to add them. I think I finally simplified it now!
Guide on Adding Them
Guide on Adding Them
Step 1. Add the character block before another character block. Refer to this to see what you should be looking for.
Step 2: Find the text string TINU. Two bytes after it is the byte that tells the game how many units are in your lineup. This is important because if it's wrong it will crash. It should always be before a character block.
Step 3: Count how many units you will now have or just add the number of units you added to that byte. If you don't know how to add hex, just google something like, "0x21 + 0x7". That should give your sum.
Step 4: Replace that byte by the sum.
Step 4: Follow this extensive guide very important:

Step 1: Finding the pointers. Go find the text string EDNID. There you'll see 5 pairs of bytes that aren't 0's. Should be from offset 0xC8 to 0xD9. Ignore the first two pair of bytes, they won't be affected by this.

FAQ:
Q: Is there a save editor yet/in the works?
A: No.
Q: Are the hex IDs the same in X region?
A: Yes, the hex IDs are the same for every region. They all share the same romfs (just different voice clips and text).
Q: My items disappeared. Why?
A: The pointer is probably wrong.
Q: My character/class is "unknown", I didn't edit the save. Help?
A: You probably just deleted or don't have the Extdata from the DLC.
A: No.
