It is very simple to configure these plugins.......if U are not familiar with how to configure your plugin then simply select fast or nice at the bottom of the plugin window.......!
If U had given me your system specs then I would have told you the write and exact setting for your system........!
there are also a few other reasons due to which the emus will not run........i.e missing Bios,not removing the kill.be,Kick.me,punch.me files from the directories......etc etc.......!
Plz post your specs.......that would be helpful for us to solve the problem........and next time any problem related to epsxe.....plz post in the respective forum.......!
