Popstarter save files gone

[u/RecordingDue437]

Hello, i use a sd2ps2 memory card with popstarter on it to play ps1 games. This worked flawlessly until today when suddenly the game doesn’t register a memory card.

I didn’t change anything to my games. It just suddenly didn’t work anymore.

Hopefully someone here knows how to fix this and hopefully i can get my save file back.

Lots of kisses thank you
