colla84: psx4m have 2 ways to save game progress: first is psx4m saves\load : in gui i make 6 slots for it, and 2 keys in config(one save file is 1~2mb and placed near rom file with same name) second is psx memcards: they are located at /home/user/MyDocs with names mcd001.mcr and mcd002.mcr (so make sure that they can be created(right chown and chmod))
