Create a new character and then save it. Now exit the game, or switch to a new window. Using a hex editor find the ******.GCD file (where ****** is the name of the character you saved) in the DATA directory under the FALLOUT directory. The last line should like this: 000001a0h: FF FF FF FF FF FF FF FF 00 00 00 00 Change the last 00 to whatever you want. Go back into Fallout. Go to CREATE NEW CHARACTER. Load the character you saved previously. You now have new attribute points available to spend. Don't go too crazy with the number. You can always go back and do it again.
WARNING: If you get a message: You Must use all your available points.... then go back into the hex editor, and change the last 2 digits back to 00. It means you maxed out all of your attributes at 10.
Similar to the other code, you need a hex editor. Use a hex editor to access the .GCD file. There is a series of 00 in the middle of the file. Change all of the 00 to FF. Now all of your character's skills will be at 200%. Also, there is a series of seven 05 at the beginning of the file. Change all of them to 0A and you will have tens in all of your stats. Then you have to change the last two digits of the file to 00.
