Mass Effect 3 Save Editing - Unlimited Credits (PC)

This is a fairly simple method but I thought I would share it with you anyway in case anyone is scratching their head trying to figure it out. Instructions for editing Mass Effect 3 credits on Xbox have been out for a while but PC saves are slightly different in that they have different endianness (basically the bytes are reversed). In this I will explain how to edit PC saves of ME3 to give yourself more credits.
First find out how many credits you have (press ESC in game). Then convert this number to hex (you can use the online converter here).
You need to take the result, which for me with 35000 credits was 88B8, and split it into groups of two characters starting from the right (88.B8). Then you need to reverse the order of these groups leaving the characters in them unchanged (B888).
Next, make a backup of your save before opening it in a hex editor. Saves are located in C:\Users\[YourUserName]\Documents\BioWare\Mass Effect 3\Save\[CharacterNameAndRandomNumbers]\Save_[SaveNumber].pcsav. The hex editor I used is called XVI32.
Use search to find the hexadecimal number you found earlier (B888 for me).
You should find your credits stored in 4 bytes starting with your credits in hex and followed by 0's (e.g. mine has B8880000). Replace this with FFC99A3B (999,999,999 credits) then save your file. If you try and load it up now you will find that Mass Effect says it's corrupt. This is because the checksum is wrong.
Open your save in this checksum fixer and press "Fix Checksum". You will have to type "*" in the file name box and press enter to make it show PC saves since it is only looking for Xbox ones.
It is made for Xbox so the checksum will have the wrong endianness. To fix this, open the save file in your hex editor again and scroll to the last 4 bytes of the file. My checksum was F3E96500.
Do the same thing you did earlier with the credits. Split into groups of 2 characters (F3.E9.65.00). Reverse the groups (00.65.E9.F3) and replace.
Load up the save and you should have 999,999,999 credits.

That 's a neat trick! Thanks very much for sharing. Is there a chance that something similar can be done with the galactic readiness rating?

Artmoney worked fine on ME2, probably work just as well for ME3.

Yes you can do that with readiness. You can edit unique war asset values (since they're added up in-game under each category such as Alliance, Alien, Crucible, etc.).
The values start at the offset A15C in the file and the values are dwords. All you need to do is edit one entry anyway, since if I recall correctly 7000 is the largest trigger value for the best ending.
