encrypting dc gameshark/actionreplay code

In this library, I found a proggy dcgscdx and tried it.
As, its explanation says, it converts just encrypted VALUEs
and it doesn't decrypt any ADDRESSes. ...useless?!

I tried to hack encrypted address but not successful.
Anyone already cracked their algorithm of address encryption?

Please help me use gs/ar codes.
