Mines, which were PS1 cards, were working some years ago (and I hope they still do). So just in case I copied every file, not using an adapter, but with a jailbroken PS2. I don’t remember exactly how, I just know I had FreeMcBoot on a new PS2 memory card (which I think I got because a friend had an already jailbroken one) and with that I could copy the files to the usb, then from usb to pc.
Im not sure that it’s not already non-functional to be honest, it hasn’t been used in just about 2 decades
And also im not entirely sure where I would source an adapter needed to hook one of these up to the PC to be honest :3
