The Magic Formel is for the C64, but a C128 Version was planned and never released. According to the manual. if used in the C128, it will not autostart, but start when you enter C64 mode manually. It's a freezer cartridge similar to the Action Replay, it has a good freezer and a RAM fastloader. In a test published by 64'er magazine they said that both are better (faster, more compatible) than those of the AR. You start the freezer by hitting the restore key. In case you need the ROM dump, I think I saw it on one of the cartridge ROM sites (maybe in the "unemulated" package). Maybe I have a dump of the version 2 ROMs as well, but I heard that some changes other than installing the missing socket are needed. AFAIK V2 added some application programs like a simple paint program and text editor.
