Tiny Encryption Algorythm

[quake_ger]

Maybe somebody can help me with this? (but only the decryption code)
All I know that there are loops and in every loop it add delta.
But more I don´t know. I am not really a newbie but the sample codes on the internet are only in C and I only know Visual Basic.
I don´t understand C/C++.
Can somebody explain it to me or give an address where I can find a Visual Basic code?
