SNES + Epicjoy Flashmaster cart

Hey, has anyone used this card or simmilar? I'm having trouble reading the save file of a game I was playing and I don't know what I'm doing wrong. https://pl.aliexpress.com/item/1005007204593961.html

I've been playing Breath of Fire 2 for about 10 hours, saving my gameplay in-game. I see that the save game is on the SD card, but I'm not sure if I'm launching it correctly or if I need to do it differently.

Have any of you encountered such a problem?
