Can't get ePSXe to load games

[Dyer92]

Right guys i need some help. Just downloaded ePSXe i have all the current bio's and plugins. However i have downloaded a Final Fantasy 7 which is supposed to be ISO but it won't load. I have downloaded the 7z converter but can't seem to manage to actually convert it or do anything with it. I am a newbie so please simplify if you can that would be great.
Cheers

FF7's file might not be an ISO but rather an ECM file. Use EP's ECM Tools to UnECM the file and make it become a Bin file which is usable by the ePSXe.

The download link for the tools http://www.emuparadise.me/PSX/ecm%20tools.rar for your convenience.

This link can be found on most of the PSX ISO's as it's common to make the disc image of the game into an ECM file for whatever reason I still don't know.

Among other things it can help you understand Extension of files easily.

I would go further and just link in the guide at http://www.epforums.org/showthread.php?57757 that deals with both ecm and ape files and exactly what to do with them to make those work fully with ePSXe and modded consoles including basic ePSXe setup for games with CDDA sounds/music (All required tools are also in that thread)

ecm (error correction module) just gives higher compression when used in combination with 7z
ape is a loss-less audio codec again has better compression than raw/wav format and because it is loss-less all the quality is kept from the original sound

These are very good reason but it also means that it takes longer in the long run for the files to be restored to a usable state and must be converted back to standard bin+cue format disc images
