I don't think you can edit your save game without having Homebrew.

 

[ErakezZ]

If this is so, you know a good guide that can help me to aply homebrew without geting a ban? I heared that you can start homebrew over a usb stick,so you dont have it on your switch directly.

Thanks

Are there any cheats that increase the game speed/can they be made? I have heard the steam version at least has a cheat engine/mod that accomplishes this. This would be the single greatest QOL improvement for the game IMO. Playing the GBA games with a fast forward emulator has spoiled me.

It simply plays too slow and needs a fast forward mode of some sort. Even the GBA games had this, the abilty to skip promps only goes so far.

Incase someone still needs dat "allcards" save:
https://gbatemp.net/threads/yu-gi-oh-legacy-of-the-duelist-save.537008/

Unlocks 9109 cards for me.

Edit: So ive made a backup with checkpoint and changed the data, when i went back into game after importing the save, my money was the same as before. So I dumped a new save with Edizon and when I look at the hex data, the values are set to the new money value and when I try it with KuranKu's save editor it immediately defaults to the new value I set earlier from checkpoint.

Anybody know why the change isn't being reflected in-game?

Does anyone have a complete save they can share?

 

[seany1990]

So following on from my previous post, there appears to be a strange method as to how this save functions. I tried editting the coin count a few weeks ago and couldnt get it to work, as the game updated to version 1.1 I just assumed it was because the save data structure changed and old methods didnt work anymore.

Fast forward to yesterday and I upgraded the size of my micro sd card which meant backing up the save and reapplying it to a fresh install. What I found was my save is now a few days behind when I last saved and I also now noticed my coin count has changed to the number I edited before. If anybody knows how the saves work for this game I would greatly appreciate it

Has anyone figured out how to calculate the checksum for the new save file format for 1.01? The savegame.dat file is different for me now in that they are saved as savegame2020.dat files instead and the format is now a different file than 1.0.

Also, has anyone figured out how to get all cards but not clear the entire series/progress? I want all cards to make my own deck but clear the story on my own and not have it all unlocked.

EDIT: Nevermind, I figured it out. I unlocked all the cards on my save and updated the checksum properly on 1.01. All is good.

What's a checksum error? Does it mean when the game loads and checks to see if your save data is the same it was before that it gives an error if it isn't the same as when you last saved it? Because I tried to edit my DP and got a data error.

Yes Checksum Error

Trying to give myself maximum DP just corrupted my data.

If only I could battle online it was perfect game
Probably will buy new switch

Are you saying that the update messed up the way hex editing is done?

I dont think the save format has changed (or I did but I don't anymore.) The issue is with how backing up and applying save edits works for this game. I dont know if its something to do with checkpoint, atmosphere, hetake or what-not because if I edit my save I will see nothing changed in game.
