ROM Hack WIP BOTW Save Editor (Homebrew App)

[Jpe230]

I made this simple Homebrew app to edit your rupees, weapon durability and arrow quantity.

It is still a WIP, I've got much to improve.


IT ONLY WORKS ON V1.5 OF BOTW Now it works for all versions


Instructions:

• Open BOTW with your current user. Wait until the title screen, then exit it. (Close the game, too);
• Open the Save Editor and select save file slot. (Usually it is 5 or 0).
• Use DPAD UP/Down to Increase/Decrease the integer. Use DPAD Left/Right to move the cursor.
• Use L/R to move between items.
• Press A to Commit Changes.
• Press + to exit.

Disclaimer:

• Please always make a backup before editing your save file; I'm not responsible for any lost save file.
• This is a WIP, it contains bugs.

If you want to contribute please DM me, I seriously need help.

EDIT: I updated the zip file, it contains 2 nro's one for normal mode and the other for master mode. Now it mounts the save directory now you don't have to use Checkpoint to extract your save file. But ALWAYS make a backup.

If you want to contribute please DM me, I seriously need help.


Here is my project in Github if you want to compile it/fork it/see the code: github (dot) com/Jpe230/BOTW-Save-File-Editor

Wow this is pretty awesome! The ability to edit saves on device is infinitely appealing and convenient! Might I suggest that you work with the developers of Edizon? They have an excellent foundation and graphical front end for backing up / restoring saves on device. The next part of what they are trying to accomplish would then to have on device editing of the aforementioned saves. Once again though, this is awesome! Keep up the excellent work!

Can't wait to see this get more features. Great work.

Haven't tried it yet, but I like what you've done here, great work!

Is there a value that allows for infinate weapon duribility? Would love to have a shield that can last longer for epic surfing.

I followed the instructions and I don't think it's working properly for me; no matter which save number I load in the editor it says I have 0 rupees and I can't use L/R to switch to other categories

I have another save backed up in Checkpoint, I'll try removing that

EDIT: Fixed it! Turns out the problem was the Save editor only let's you choose saves 0-5, while my save folder showed 0-7 (the manual save being folder "6") I deleted folder 5 and renamed 6 to 5. Maybe the 2 additional save folders are created when you start a game on hard mode?

Yes it is a currently a problem when you have master mode, you can edit the code easily to fix it

Done! Here's an updated version of the .nro with master mode fix for anyone who can't fix it

mediafire [dot] com/file/4cnu5uvru5d5f87/BOTW-Save-File-Editor.nro

Lines 158 through 176 of main.c should read:

    if(currentItem == 0){
        printf("\r");
            printf("%d", slot);
            switch(c){
                case 0:
                    slot++;
                    if(slot == 8)
                        slot = 0;
                    break;
                case 1:
                    slot--;
                    if(slot == -1)
                        slot = 7;
                    break;  
               
            }
            printf("\r");
            printf("%d", slot);
    }

You should play the game and not the other way round!
I'm really tempted to get this but I'm afraid the game will become too easy
Anyways thanks for this awesome tool!

                        slot = 0;
                    break;
                case 1:

                    break; 
              
            }
            printf("\r");
            printf("%d", slot);
    }

Worked perfect for me. Master Link is now rich, has an Indestructible Master Sword, Unbreakable Shield, and Infinite Light Arrows.

Use Checkpoint to extract your Save File to your SD Card, name the folder "botw". <-Important

I'm not getting this bit. The folder has to stay in checkpoint folder or moved to the root of the SD card?

 

[SwitchMii]

Amazing!! So much easier than bringing the save files to the computer

 

[Greg956]

I only see rupees as item, others are without name, how do I know what I edit?

 

[JimmyDean42]

Thx, this is awesome @Jpe230 ! Didn't want to have to copy my save to PC every time to refresh my weapons.

I have all my homebrew in a /switch/ folder on my SD card, so I changed the folder location to point to that so I didn't have to move stuff around on my card. Also added the mastermode fix via @Syynx (even tho nowhere near there yet).

EDIT: Nvm, wasn't clear to me what I was looking at.

What do you mean you changed the folder location? What did you change exactly?

 

[JimmyDean42]

From /Checkpoint/saves/0x01007EF00011E000 The Legend of Zelda Breath of the Wild/botw/ to /switch/Checkpoint/saves/0x01007EF00011E000 The Legend of Zelda Breath of the Wild/botw/. I have all my homebrew programs in one folder in my SD card. Just didn't want to have to move my Checkpoint folder out of there.

I have all my homebrew programs in one folder in my SD card. Just didn't want to have to move my Checkpoint folder out of there.

The original code says: char header[] = "Checkpoint/saves/0x01007EF00011E000 The Legend of Zelda Breath of the Wild/botw/";

This is a relative path. If you place the Save editor in sdmc:/switch/ then it will look for the Checkpoint folder in the Switch folder. Your edit simply turned it into an absolute path so that the save game editor can access the folder no matter where on the SD card you place it. Still a good edit, but the original worked fine for me.

Who said you HAD to edit your game files? This is not for people who want to play normally, this is for people who want to mess around!

AHHH, gotcha. I have every .nro in its own folder (so /switch/BOTW-Save-File-Editor/BOTW-Save-File-Editor.nro). That's why it didn't work for me. I guess putting it in the same folder as the /Checkpoint/ folder is easier than editing the code

Thx for taking the time to explain!
