[PSX] Switch Memory Card in the same Port/Slot (inside game)

There’s some games like my current “WWE Smack Down 2” where to do some actions like copy custom fighter need:

  1. Insert Memory card with the caracter which you want to copy in Slot 1
  2. Choose Caracter
  3. Switch again to the original memory card to complete the process

It seems that game (and maybe others) use the psx ram to store temporaly data and im afraid this cant be done with external memory card manager.

Can some one told me if i can do this? thanks in advance

Does someone know? please
