Note 1:
With this code, it should allow you to purchase any weapon/modification available in the game. Remember that certain mods have to be purchased for others to appear. The weapon part of this code was snipped of useless values, but the mods part either doesn't have useless values or I am not aware of them.

Note 2:
With this game, and the Weapon Modifier codes, use 00-1F.
