I think you should be okay with x10 but like I said don't use the one that says dangerous try to disable codes and make a save before anything big goes down and make a save backup in jksv or chekpiont that way you can roll back if issues rise

After contents did you put the file...
If yout using the one that says caution 98 of important items that's what broke you save but yes the item. Codes can have I'll effect if used incorrectly I've used the 900 one a few times and haven't had issues but I also never have codes on at important times in the game custsceens and boss...
As far as I know the only fix you can do is roll back to a save before you got it and make sure your items are at a reasonable range say 500 at most maybe less if you want to be safe and make sure the cheat is not active when you get it
There is already a code for picking up less items then the max in the cheat file
These are 1.1.0 but ther are also ones for 1.0.0

Just saying most ppl that broke their save used something they should not have early I have nt had a problem yet but I guess I don't use any of the crazy codes earthier durability max and 900 items/food and moon jump on ocasion
