New Patch site besides gamecopy world...

[Mith22]

Does anyone know of ANY other sites on the internet that offer patches for games besides gamecopy world? Some have to exist, since I own games that have been patched, and the patches are NOT on gamecopy world.
I am asking because I definitely need a patch for Dance Dance Revolution 5th Mix and Extra Mix. There are gameshark codes for Extra Mix... but they barely work. I would much rather just copy my game and patch it. There are no codes for 5th mix though.
