well i just checked it.
i used these addresses in a single player mode or when i'm a host to get skill points. Besides in multiplayer mode sometimes when i had changed values of these addresses host got skillpoints.
1 Byte -1444D2BF0 - iw6mp64_ship.exe+44D2BF0
2 Bytes 1444D2BF0 - iw6mp64_ship.exe+44D2BF0
4 Bytes 1444D2BF0 - iw6mp64_ship.exe+44D2BF0
1 Byte -1464575A5 - iw6mp64_ship.exe+64575A5
p.s. if i will change value only in 1444D2BF0 i will have for example 99points, but i can't spend them BUT if i also will change 1464575A5 - it will work
