How to add a removed game from Steam to wishlist ?

There`re several games that were removed from Steam and I want to add them to my wishlist. I heard about some java-scripts ...

For example:

http://steamdb.info/app/10170/

http://steamdb.info/app/10000/

http://steamdb.info/app/12720/

http://steamdb.info/app/21080/

http://steamdb.info/app/21920/

http://steamdb.info/app/42830/

http://steamdb.info/app/2790/

http://steamdb.info/app/4730/

( These games are from this thread - http://forums.steampowered.com/forums/showthread.php?t=3071895 )

Don`t ask why :)
