A way to bypass patches - Clear System Cache, sign into Black Ops offline, start up a solo zombies, and then sign in.
You might find a GPD that is already modded, but if not, mod it yourself!
Xero is a modding program that allows you to create modded GPD's for black ops.
After Opening XERO all zombie mods will be in the second tab. Multiplayer mods go in the third tab.
edit: back and start button binds are patched but not dpads.
These will be what you add things too.
say *TextHere*" (make text appear on side)
give ammo (Give max ammo)
g_speed *Value*(Move Speed)
dropweapon (drop current weapon)
noclip (No Clip)
ai axis delete (kill all zombies)
timescale *value* (change speed of game)
give *weaponname*_upgraded_zm (Give weapon no asterisk upgraded gives pack a punch variant)
Most stuff in the GPD will be easy to figure out what it does here lets look at some code
player_clipSizeMultiplier 999;magic_chest_movable 0;sf_use_ignoreammo 1;player_sprintUnlimited 1;player_sustainAmmo 1;perk_weapratemultiplier 0;Revive_Trigger_Radius 999ClipSizeMultiplayer, ignore ammo, and sustain ammo are all important for bottomless clip, magic chest movable 0 makes it unmovable basically everything is named easily.
So lets say you want a Galil and ray gun both pack a punched.
DPAD_LEFT give galil_upgraded_zm;;bind DPAD_RIGHT give ray_gun_upgraded_zm;When adding your own gun codes make sure you use the "give" command.
