Using the latest nightly I’m seeing an issue with save files with the MednafenPSX core. It seems to be partially ignoring the “beetle_psx_use_mednafen_memcard0_method =” setting in core options. If I set that to Libretro instead of Mednafen then it will still create a separate .mcr format save file for the second virtual memory card.
For example if I load up Spyro then it will create both: Spyro the Dragon (USA).srm and Spyro the Dragon (USA).1.mcr
It also seems to be partially ignoring automatic overrides. If I set it to libretro and use a partial config file to act as an override for changing the save file directory then it will create the .srm in the override save folder and the .1.mcr in the default save file directory.
