joinski ok thanks, my problem is the compatibility of roms. the Libretro emulator uses the core you name but only reads the certain bios, I did an update to the bios I already have all of them but I realize that the emulator is the problem ... and I wanted to use ePSXe instead of Libretro, look in the folders Where it is stored modify the files to see if adding new ones by hand the bios could get to read them but I had no luck so it occurred to me to add another emulator and when I go to the menu they are to choose which one I want to use.
