Credits
Here is how it Really does work :In the game folder you will find a folder called "PlayerData". Open that and open the file TD6.pm0 (the 0 can be another number also depending how many names he or she made) Using an Hex Editor (like Hex Edit ) go to line 630 and you will see in 'box' 5 and 6 these Hex numbers : 409C 0000 (the default when you start a new name ) edit them in FFFF FFFF. This will give you enough credits to get all the things you can get without destroying the game. Note: Always back up your files before editing them.
