There is only one thing I don't like that much, is that it still doesn't support compressed images, it has become a standard for almost all emulators, so why not pick up the trend?
Well, v1.80 does support PBP images which is compressed. You can have multiple iso's in 1 PBP file.
For instance like FFVII, you can have all 3 disk images in 1 PBP file and when you run the PBP file through
ePSXe it will ask you which disk you would like to play.
