Issues

ePSXe has stopped working

When trying to run any game or even the BIOS, ePSXe will crash and an error message will popup saying "ePSXe.exe has stopped working". This issue happens most commonly with ePSXe 2.0.5.

Solution

Open ePSXe
Click Options
Click CPU Overclocking
Set it to x1

Background music does not play on some games

In some games, the background music will not play, but all other sounds in the game play without issue. This is usually caused by playing the game from the File -> Run ISO option. These games require the use of a physical CD to play the background music. You can fix this issue by emulating a physical CD.

Solution

Download Mooby2 CDR
Navigate to the ePSXe folder and extract the zip into the plugins folder
Run ePSXe and click on Config -> Cdrom
Change the Cdrom plugin to Mooby2 cd disk image driver 2.8
Click Configure
Check Repeat all CDDA tracks
Change the CDDA Volume to 0.50
Click OK and OK again

Now when you want to play an ISO game run it from File -> Run CDROM and the background music should work.
