PS2 v4- backing up singstar and DDR

Hello! Newb here. I’ve googled and looked at many threads and can’t seem to find the exact info I’m looking for.

I just bought a hardly used fat PS2 version 4 I believe (8 screws, U2 serial number). It came with 3 games.

I’ve ordered DDR supernova and will also be getting a couple Singstar games (Pop, 80’s etc) for my daughters and their sleepovers. Possibly Karaoke Revolution. My kids will be brutal on the games so I want to back them all up right away.

I’m thinking of ordering a fliptop cover with Swap Magic 3.6 or 3.8. Will either of these guaranteed work for these particular games? I don’t have the time, energy, or knowhow to fiddle with anything - it has to be idiot proof.

I currently back up my DVD movies with DVDfab decrypter - can I use this for games also?
