ROM Hack Discussion Fire Emblem: Three Houses General Hacking

[SkittleDash]

So I start the game then go to cheat I guess in SX menu and enter them there?

SXOS/titles/[GameID]/cheats/[BuildID.txt]

Once you have the file in there, start the game. Then press the home button and enter the SXOS menu, then cheats.

 

[linuxares]

I gonna ask @WerWolv if it's possible to group things in to sections like "Items" is one "House Black Eagles" one etc. So it's less cluttery on the front page.

 

[alexj9626]

Could somebody please make Mercedes a dancer in this file? Have tried for a while but i just cant. Hope it is not much to ask.

 

[BUSHMASTER]

Ok can Any one please just post me a save game file that has max level for every character and other stuff if possible please?

 

[EmulateLife]

SXOS/titles/[GameID]/cheats/[BuildID.txt]

Once you have the file in there, start the game. Then press the home button and enter the SXOS menu, then cheats.

So do I just make a txt document and put the codes line by line or?

Maybe once someone figure out how to change each character classes, seem like the one you pick to represent in that dance competition is who get the class.

Yes, i know, thats why im asking. I was looking for a way to identify it but... im no expert in this so i didnt get any results, but yeah i know how to get the class and she doesnt have it cause i didnt have her by the 12 month.

All data in that Part 2 save are still in the same location in the save.

Also there isn't much space in the save, most of the save data is 400 Items Slots (4 Byte), 60 Character Slots (0x230 Byte), 500 Unknown data Slots (0xD0 Byte, my guess is Battalion or NPC data) and the rest is some minor data like flags, money and misc/gift items.

But it is possible that the memory location is different, because the game does the same when going into a Battle.



You can try if this code works, last time when i did mess with character id's my switch froze ^^

Looks like it worked for me! Will look to see if anything bugs out but working great so far~~

Extract and place it in sxos/titles

 

[EmulateLife]

Extract and place it in sxos/titles

Thanks I appreciate it, do I need to load the cheats each time I play?

 

[SkittleDash]

Thanks I appreciate it, do I need to load the cheats each time I play?

I believe they save. So any cheat you apply will still be activated next time you play.

 

[burnham90]

Great work on the cheat codes! Would really love a max support cheat for everyone but it seems like it's hard to make. Unlimited gift items lets you easily get Byleth and everyone supports, but it won't help you get non-Byleth supports.
EDIT: Also, it seems that if you don't get Byleth-C supports by Part 2 you're locked out (greyed out) of them, "too much time has passed" the game says.

 

[EmulateLife]

I believe they save. So any cheat you apply will still be activated next time you play.

I was able to load the codes, and selected several such as Byleth Health 199, and he's in the first battle but his hp is like 27. It's like the codes aren't working for some reason.

 

[neomy2]

I used cheats from @kazuki_chan8's post, first time I activated all cheats accidentally and the enemies have max-stats too, then I removed all max-stats cheats but Byleth's and Edelgard's, restart the game (close and load), the enemies are still max all stats.

But this morning, I tried again, then the enemies no longer have max-stats cheats ... maybe I did something wrong, or one (or more) of max-stats cheats is buggy

Here i compiled the cheats so far. Use after update your game to v1.0.1.

--------------------- MERGED ---------------------------

Thumbs up for those who working on these codes XD.

could you post the cheat that you used that affects the enemy?

The Byleth/Edelguard codes are the same posted here very early on. Did you enable all the codes or just the ones specific to Byleth and Edelguard? Should only be enabling the codes for your house or recruited characters.

Given the amount of codes floating around, it truly might be best to wait for a proper editor. Oh and do backup your saves or have multiple saves just in case.

this is what I used, but before this, I did activated all the cheats in txt file, then removed some from file to this ...

[moopas]

I'm pretty sure it has already been looked into, so just tossing this idea out there anyway.

Can we look into skills and abilities code-wise, or however the editing process works? If so, would it be feasible to just check out the skill that Byleth has that multiplies the exp gained of adjacent units by 1.2, and see what makes it tick? Then possibly just make the "adjacent" or effect area be map-wide, and chane the 1.2 to something like 2x, 4x, 8x, etc?

That way we get the exp multiplier that everyone keeps asking about. Or perhaps just see what the skill changes in units adjacent, and just have the cheat toggle that on always, or any other way. Basically, just look at the built-in exp multiplier and fenagle it to work how we want.

Like I said, pretty sure if this was doable, it would have already been done, just tossin a thought out.

 

[8bitNoble]

I'm having some issues getting codes to even work really, using Eidzon I have a bunch of codes active, but I'm not seeing stat changes or max gold working. Is there something I have to do to get things "Activated"?

 

[iKing_PR]

for those who are requesting the max gift or have gifts/ materials cheat please note that there is an code for it called Material/Gifts is not reduced

Check on this forum for that code and your life will be definitely easier

Same as any other exp code, you first need to find it if you want to make it as a cheat.

But what you are trying to change can't be found in a fixed location in memory, it is loaded from a skill database file, so editing it would require to use a modded romfs and i guess no one wants to waste 10 GB 6 GB of sd card space just for an exp mod?

 

[moopas]

Ah, alright, just wondering what would and wouldn't work. I dont mind the grind, the only thing I personally want is unit maxing (for special class skill, not levels) so I can just class change at will and try out builds without being stuck at a low class with poor growths that I don't wanna play just to unlocks the skill anf "master" the class.

 

[eserikto]

Here're some class xp cheats I generated. This is still heavy WIP, but a lot of people have been asking for xp cheats. I'm still pretty early into the game, so I only have a couple classes unlocked. I've left a lot of class names as offsets and am missing pretty much everything after intermediate. I'll fill them in as I go along.

It'll set class xp to be max - 1 so the next combat you participate in will master the class + get the skills/abilities. I don't think these work if you're in battle, so use them before going in.

Beware, this is a huge file with a ton of separate cheats. You may want to go in and pick out only the ones you want. I don't like to set values out of their in game clamps, so I didn't use a loop for this.
