and im pretty sure there is no algorithm that goes to the nx codes and otherwise you would need to hack the server (i may be wrong because there is no algorithm with xbox live cards) and i doubt you have most if not any of that stuff.
And Shepherds we shall be
For thee, my Lord, for thee.
Power hath descended forth from Thy hand
So our feet may swiftly carry out Thy commands.
So we shall flow a river forth to Thee
And teeming with souls shall it ever be.
In Nomeni Patri Et Fili Spiritus Sancti.
