comment How do I generate decryption keys for the IDEA algorithm from the 128 bit key?
I did not had any problem with 'Modular Inverse'. I am stuck with the rest of the straightforward!

How would you invert the steps whose output was an XOR or two 16 bit values? You only have the resultant XORed value and you need the operands.

@PaĆ­lo Ebermann: That doesn't seem to work, although I believe that the sub-keys generated by the above method are correct! +I understand that this is not a programming Q&A but I thought they are closely related, to some extent. I'll be careful next time.

For folks who don't know C#, ushort is a 16 bit unsigned data type and the string binaryKey in my code is strictly 128 bits.
