Memory Card problems with Fire Cube

Hello, I’m not very knowledgeable to emulation but for the most part I’ve been pretty successful as far getting RetroArch to work on my firecube. But I seem to have hit a wall in regards to getting memory card saving to work with Playstation 1 games. Every time I save via memory cards and close RetroArch, my memory cards are erased. Also I’d like to refrain from using save slots if at all possible. Any help would be much appreciated because I’m completely lost atm and googling this topic has not aided me in the slightest…
