First, you must locate the bank you want to edit.
These are located in
C:\Documents and Settings\(Username)\My Documents\StarCraft II\Accounts\(Random Numbers)\(Random Numbers)\Banks\(Random Numbers)
Just browse through the bank folders until you find the desired one..
Like mafia's bank is called MBank
Squadron TD is called STD (lol failname)
MineralZ is called Banks
You get the point.
After you find a bank, it will look something like this.
Spoiler:
First note: the parts in red are the key parts to edit. Sets your level exp kills unlocks, etc.
However the blue part is where is checks all banked values to make sure you didn't cheat.
Meant to prevent it at least. Mr Nukalizer from d3scene created a re-signer/re-packer so it writes the sig value.

So, open your desired bank, edit the values you want, re-sign and re-save. It's pretty simple if you look at the application screenshots to see what I mean.
However games like Mafia become a bit more complicated, because they write to 9001 different keys and they all have cryptic names.. So you may need to unlock their map to find what writes to what
Gl. If anyone needs hacked banks because you don't get this, post here and I will give it to you..
