Multiple memory cards issue

[hyde5991]

Hello, I would like to know how to have a second memory card available

I'm trying to play Yu-Gi-Oh Forbidden Memories (PS1, mednafen core) and the game has a multiplayer option, but whenever I try to play, it only recognizes a Memory card in the slot 1, but for de slot 2 it has no data, I have tried to make a copy of the respective .mcr file and also saving with the Save option in the game, but as it only recognizes one Memory card, it will not allow me to save different games, only overwrite the one that I already have.
Is there any way to have multiple saved games (using the Save option in the game or saving in any other way so the game allows me to play multiplayer mode)
Thanks in advance.
