Firmware download for YS menu

Does anyone know where to download the firmware, for the YS menu? I know its a tedious thing to download, but I have M3 simply, and need it to run specific games.

Does this work on M3 simply, this is the kind of card I use. I also want to know HOW to apply the files and whatnot to my card.

Scratch that, found out how on my own, its okay, it just wont fix the freezing problem of HGSS, and other games. WHAT PEOPLE SAYS LIES!
