i need help with some HARD Adresses

i already made a couple of hacks and i was wondering if sombody could help me with these adresses...:

O.P.K... Got no idea how to find it and which values...or what to freeze to ...

Unl ammo ??? can find the adress but how do i freeze it ... ??
( question bout it btw, could i make an ammo hack for each wep or is the adress that i find with a mp5 of k2 the adress for that wep... becuase i was thinking of that u get new ammo....)

invisible.... Got no Idea , just like OPK

maybe S(hoot)T(rough)W(alls) but i got no idea..... like OPK


When i know one or more of these adresses ill make a hack and ill make a public hack for MPGH which contains these Adresses Rep for the ones that help me !

You can find a tut on finding unl. ammo + pointer in the tut section and as for the other hacks am not to sure i have never seen any tuts on how to find the addresses for them.
