Download a PPF Patch Then put it in the ePSXe "Patch folder"
(This only works using the CD-ROM )
Open P.E.Op.S. CDR Driver 1.4 Config(If you've never used this before config it like the image)
Find the PPF patch you wanna use in the "Patch folder" (im using FF8 as a reference)
Also, If your game uses multi-disks selected the right PPF patch, E.g- Disk 1 to 4
(You have to change when you switch disks)
Press OK then Run Cdrom to start playing
