Password Format
---------------
1) Description -
Use the Data in the password to replace the data in the memory
at the offset address (according to the game file)
2) Format 1 -

* 3 data bytes per string
* [Gaaaaaddddddccc]
'G' = Means Game Doctor Format
aaaaa = Offser address of game file (Excluding 512 bytes header)
dddddd = 3 data Bytes (If the second ot the third data is '00',
this means that the data is uncganged in
the second of third byte)

3) Format 2 -
* 'FFE' Format
* 24 bit address space assigment
* 1 to 36 data bytes per string
