I take no responsibility for any damage or loss caused to your save files. Make sure to create a backup before modifying them.
If you don't know how to make a backup, simply go to and copy the save files to another folder. You can also copy the entire “Savedata” folder to a different location. Either method works just fine.

This guide is intended for players who don’t want to waste hours farming items with ridiculously low drop rates or for those who, like me, already got them on another version or platform and don't want to burn the MINAC into their monitor.

You’ll need a hex editor for this process. In my case, I’ll be using a plugin that can be installed directly within Notepad++.

Once you have Notepad++ installed, go to Plugins > Plugins Admin.

Use the search bar to look for HEX-Editor, tick the box next to it, and install it.

With the plugin installed, open the save file you want to modify. Do this directly through the program by going to File > Open.
Remember that the default save file location is:

In my case, I’ll be opening my second character: Save0002.sav.
The program should now show you something like this:

Once the save file is open, we’ll inspect it using the HEX-Editor.
Go to Plugins > HEX-Editor > View in HEX.

The program should display something like the following:

Now we need to find the memory location where the variables for the items we want to edit are stored. Use Ctrl+F to help locate them.

The table below shows where the variables we need to modify are located.

The part you need to change is the hexadecimal number that comes immediately after the 01 in each reference.

(Image 7)

Convert this value to decimal to find out how many of that item you currently have.
If the number is greater than or equal to the required amount for the achievement, you don't need to change it. Only modify those that are below the required amount. You can use the Windows calculator to convert decimal numbers to hexadecimal and viceversa.

Use the following table as a reference:


In this example, I’ll be changing the number of Claptrap bobbleheads. I go to reference f60601 and locate the two digits that follow, in my case, it's 00.

We need a total of 15 Claptrap bobbleheads, so I’ll change 00 to 0F.

Once you’ve edited all the necessary references, simply save the file.

After changing every value, the final step is to launch the game. If you followed the steps correctly, you should see that the corresponding achievements unlock when you load your character.

I hope this guide was helpful, if you have any questions, leave a comment and we’ll try to sort it out.
Thanks so much for reading.
