Strange behavior when reading memory cards on my PS1
I've been having a problem with my PS1 lately. I bought a 4MB memory card, and when I tested it, I noticed it's acting strangely. As you can see in the video, the memory card is only recognized when the controller isn't connected. I tried it in another PSONE I have, and the card didn't cause any problems; the problem is only with the PS1. Any solutions?
