Hi everyone,
I've been looking around but no luck yet. There was an asian code that gave max ONLY dlc 4.00 materials, deleting all your other ones. This is pretty irritating, but technically if you refarm 1 of the *not as rare* materials and put in the present 'max materials' code, you should then have all materials x900-999, but this is tedious.
Here is a link to the thread where I give this information:

Edit: If you want to use this code, even you try buying something as simple as a Soreaway it doesnt get stored in your inventory whatsoever. Please do not feel tempted.
For now, I recommend spamming Save Wizard with your saves and request for a proper max materials code. It only requires a modification of a 2 line code.
Thanks
