anyone have the unlock gender codes for the new editor as well? I've tried both that I have found on this board and one just doesn't work and the other freezes up the switch

Hey guys, new to the boards and to switch hacking, so sorry if this seems like an easy fix, but I'm not quite sure what I am doing wrong.

I had been using the SaveEditor with Checkpoint and SXOS for a while now and successfully used it on my last 3 playthroughs without any problem, but after coming back to the game for Cindered Shadows I found that it no longer works for me. I have downloaded the updated version on the main page, but every single time I save a file from the editor it says it is corrupted and cannot be opened in game.

After some testing I found that even just opening the save file in the editor and immediately saving it with no edits still gets the file to be corrupted in the game.

Sorry again if this is an easy fix, but I'm very new to this, so i'm not quite sure what to do. Any help would be appreciated

Thank you so much! much appreciated. Thanks levanDumal as well!

*update*

so I just tried inserting the Rhea char and it's her character model with no headdress on but not the model of her in her battle outfit from the past

Here is a Rhea character file I edited. I haven't had time to play/test much though. Rhea will have her normal portrait and dialogue and can be taught in lessons but she will appear in battle as
Seiros

thanks so much for this! it sounds like exactly what I was looking for

*update*

Tried to go into battle and it took the loading screen ages to show that it was fully loaded. It then never transitioned into the battle menu. Just got stuck on loading. Thanks for the help though

When you imported the character did you put it near the last empty slots on the roster in the save editor? I think people mentioned that the characters won't work if you put them in slot 40-45 or something so I just put them at the very bottom.

I did not know that! I tried it and it worked. Thanks so much for the help and advice

I need to delete my old Rhea that I had though... not sure how to get ride of people I've imported.

Could you describe your full process in detail? Cause aside from using SXOS that's how I do all my editing, and I've not had that issue. Also, do you use any cheats / injected characters?

So i am saving the game in slot 1 in the switch before backing up 2 save files inside of checkpoint. I then eject my SD card from my switch and use my micro SD card reader to have it open on my computer. I rename one of the save files Backup and one Edited. I then open up the SaveEditor on my computer and load the edited save game from slot00. I used to make edits on it, but i tried just opening it in the save editor and immediately writing the save back to slot00 without changes and it gave me the same result here. I would write it back to slot00, then close the program, eject the SD card and reinsert it back into my switch, launch the switch in CFM, then go back to checkpoint to restore the edited version. The only problem is that now when I restore the edited version it will tell me my save file I edited is corrupted and it will not let me open it, again it is not any changes I am making in the editor, as even just loading and writing the save with no changes causes this to happen.

Any assistance would be really appreciated. Thank you!

it sounds like the checksum is not correct.

mini tutorial with example:
1)So open the file in a hex editor(, my opinion - HxD),

2)select edit -> select block:
start-offset: C
end-offset: 25B2B.

3)so now most of the file should be selected. now do Analysis -> checksums, select the checksum-32.
now you should a hex number. my file was 00CF38C3.

4)ok. so you have your checksum, look at the four bytes. in my case, C3 38 CF 00, but remember the switch uses little endian, so it reversed. C3 38 CF 00 ==> C338CF00 ==> 00CF38C3, so my checksum was 00CF38C3. so its correct and should load.

Ok so I went and checked the checksum for both the edited and backup and it turns out they are different. It looks like when I write the save inside the SaveEditor, it changes my Checksum from 00CF453F to 00CF453E.

EDIT: Nevermind I found it, its right at the top i am very stupid

Thank you again for your help

Is there a cheat to boost support gain in battle between characters to make it go quicker?

Also I got to messing around with some more injected extra characters and does Sothis not have a spell list that she learns in game? I just ended up using a hex editor to add spells for her but not sure if it will stick. It has work so far as long as I don't change classes (cause all spells to disappear).

So it turns out you can't just change the bytes at the beginning to change the checksum, as even when I set the 3E back to 3F, my checksum remained 00CF453E. So any help on how to change the checksum would be appreciated.

Again sorry if my lack of knowledge on this is inconvenient

UPDATE: So I just copied and pasted over the exact data sequence from the original Hex Code into the new one to make sure i had the same checksum at the end, but even with the same checksum, I'm still getting the game data is corrupted and cannot be opened, so it might not even be an issue with the checksum at all

UPDATE#2: So it seems when I copy over the exact same code it works, however, as soon as I eject my SD card from my PC, the Hex Code goes to all 0's

Support points can be edited via the save editor.
I would like to see a mod that allowed us to edit characters' spell lists, for one; growth rate and stat cap modding would also be nice.

Yeah, I just didn't want to manually change everyone support points in the editor and just have a x2/x4/x8 boost in game just to make it quicker while playing normally.

I also hex edited Byleth's spell list now since it is pretty bad imo but like I said earlier, if you reclass it resets the spell list.

I've made some fun cheat of my own, mainly outfit codes to make everyone use the DLC outfits, these cheats apply to every playable character, including Anna, Jeritza and the Ashen Wolfs students, all of these cheats also work during the Cindered Shadows game mode (yes, even the character unlock cheat).

These cheats also force the outfits during the cutscenes viewed in the event gallery menu if you try to view them with a cheat active.

I'll also attach some tweets I've made with screenshots as proof that these all work.

And before someone asks why the Sothis Regalia cheat is for Byleth only and not for every unit like the rest of the cheats, it's because the outfit breaks for anyone that isn't Byleth and you just end up with headless units.

be careful with this cheat. If activated too early it may break your save. I activated it early on and when I got to the bandit battle it would freeze up my game. Had to start over from the beginning and not activate it until after that battle

How did you add the spells, by the way? (I guess, as in do you know what part of the .character file corresponds to the spells?)

Got the spell list actually...
TTm2Tt7.png

yeah the offset is A0 to AB in the character files for the spell list. Durability is located right before it but probably not necessary to edit since it refills at the start of battle. You should only add spells to slots where the character doesn't already have one assigned or the next time you get into battle the default spell will come back for that slot. You can have 12 spells so for Byleth you can add 4 more since they already have 8 spells (at max rank reason/faith).

edit: Here is the list of spells
00 - Fire
01 - Bolganone
02 - Ragnarok
03 - Thunder
04 - Thoron
05 - Bolting
06 - Wind
07 - Cutting Gale
08 - Excalibur
09 - Blizzard
0A - Fimbulvetr
0B - Sagittae
0C - Meteor
0D - Agnea's Arrow

0E - Miasma
0F - Mire
10 - Swarm
11 - Banshee
12 - Death
13 - Luna
14 - Dark Spikes
15 - Hades
16 - Bohr
17 - Quake

18 - Heal
19 - Recover
1A - Physic
1B - Fortify
1C - Nosferatu
1D - Seraphim
1E - Aura
1F - Abraxas
19 - Recover
21 - Restore
22 - Ward
23 - Silence
24 - Rescue
25 - Warp
