They can't, the savegame is inside the memory of main.nso, if the file gets bigger (through an update) then the cheats need to be updated. The same goes for code patches.
Just don't update right after it's out if you care about cheats.

New Savegame Pointer is 0x1A846F0, so all codes that start with "580F0000 019D76F0" should work again if you replace "019D76F0" with "01A846F0".
All codes who used the address directly instead of that pointer, need to be updated, like the "Max Action Points" code.

Minimum required firmware is 8.1.0 and it's encrypted using master_key_07, so technically it should work with 7.0.0+.
But maybe they did add something new, because 9.0.0 was made to fix a bug with this game?

Here's to hoping they eventually get updated to 1.0.2.

oh ok. Yeah that definitely explains why people are taking so many turns to beat the early stages...Inflating stats and increase enemy levels are really not the ideal way to increase difficulty, but given how relatively easy maddening was in its previous form, I guess this is still better than having the official maddening in the exact same form.

Does anyone know if it's possible to switch from the pre-released maddening to the official maddening on an existing save? Since the changes are minimal, I don't feel like starting fresh again. But I definitely do want to have the higher stats enemies on my current playthrough.

Yeah thats good too. Maybe someone can do this later on. Just enjoy the ride until then.

I don't think there's anything you need to do to switch to the official one.
The difficulty setting is just a single value in each save file as 0, 1, 2, 3. The moment u updated ur game to 1.0.2 then ur Maddening gameplay should be the official one already.
But from what I see so far, the gameplay and change is still same as the pre-released Maddening.

Excuse me. I was wondering. Since Three Houses has a new update, will the cheats for Edizon have to be modified at all? I’m hoping not. But I wanna make sure though.

Seems like 91wii got it covered, but requires certain member level to access them.

Until the dlc is dumped i can't say for sure, but for now the save editor should work without any problem,
i made sure that any item id is possible, even if it's not in the db, but i already made a new build with the updated files.
I will wait for the dlc to make more changes.

Wait - are you the same Falo that made the QuickBMS scripts to extract various Xenoblade files i used almost a decade ago?

oh I see, that makes sense. But if it's the same then yeah, it would be disappointing, as we already got to play maddening for weeks now so this update essentially brought nothing new

no decrease in pts likely is the updated version of our "renown does not decrease"
I'm not sure the first one is even a cheat, so don't know why it has 3 lines of cheats. No clue what the last one means either :/

Darn. Some of the new codes are hard to understand. Perhaps I should just wait until ones are made that have a better explanation?

U could always ask which code is hard to understand.

I can provide better translation later

Okay. Well, I can figure out SOME of them, but the ones I’m having trouble with at the moment are Material Edit Effect Off, Weapon/Magic Durability, non storage limit, and Unlock Extra?

...
how could you have a hard time understanding what "weapon/magic durability" means? No offense but anyone who played the game with two brain cells should have no trouble guessing what it means...
Unlock extra already exists under the exact same name in our version of the cheat codes. It basically does exactly what it says, unlocks all the contents under the "extra" menu...

Well, I just want to confirm things is all basically.

i did tested some cheats out like exp/job exp and they seem to work.
tested durability /magic out and its glitchy that it will max out anything in ur inventory to 99 like potions etc.

still need update for 1st item x99 better then dura/magic and the class max exp too.

Do you mean the class max exp? I can do it later, I have the code.

yup you're right. Just loaded the old save right before GD final battle and the changes from the new maddening is present and very visible.
Spoilers for GD
The final boss now has a whopping 359 total stats lol compared to 319 in pre-release maddening, and even most regular pawns have stats similar or higher than my units, in the range of 250+. The 10 elites all have high 200s, with some reaching 300.
This is gonna be a fun fight...
