I’ve been trying to figure out how to use a memory card with emulationstation and RetroPie. I read the docs on PCSRearmed and found the memcd1 option. I tried adding this to the COMMAND argument for playstation 1 in the es_systems.cfg file, but this resulted in an error.
Currently I have a separate memory card file for each game that has the same name as the rom file plus the. .mcr extension.
For example: “Metal Gear Solid.iso” is the rom image, “Metal Gear Solid.iso.mcr” is the memory card file. How do I get the emulator to launch with this memory card loaded when I launch from emulationstation?
