explains everything you need to get these working in ePSXe with CDDA sound
download links in that guide are at the top, just skip most of what is said there because you already done half of it
and look at the ePSXe notes, then either just follow the notes and or download what you need.
I strongly recommend the shark enhanced mod for ePSXe 1.8.0, you will see why if you check the link out there, that just links to another thread that explains how to install & what it does, that also including the download.
I used tools in there that anyone can use, so may of gone a different way to some, but that is to cover more OS versions, as some of the software than can be used does not work for everyone.
