MDF? MDS?

[heffer]

i have NTSC version of Gran Turismo for psx. the image files are not .bin and .cue, but instead .MDF and .MDS. i've never seen these before, how do i play them? i have already tried mounting the MDS file and chose 'run cdrom' from ePSXe to no avail. i've opened the virtual drive and found the MDF/MDS to contain lots of .DAT and application files but dont see a .exe. basically, how do i play this game?

here's a list of wut it contains if u must know

Those are images created with Alcohol 120%, but you can mount them withouth problems using Daemon-Tools.
