game wont work

Alright I downloaded harvest moon: back to nature as a torrent for psx, and set up the epsxe emulator. When i go to use the "run iso" command it says theres nothing in the folder the game is in. there are two different files in the folder. the extensions on the end of them are different, one is extension .mds the other is .mdf. how do i get it to work?

have you configured your plugins correctly and do you have the BIOS?

see i duont no what all that is. for bios i have scph1001, and for plugins i have gpuPeteOpenGL2. is this alright or do i need actual bios for the game? and should they be with the download?

Do you have the CD-Image reader plugin ?
