Confused When Play with 4 disks

Hello Guys... I just wondering How to change disk1 to disk2 in epsxe because I am playing legend of dragoon ( actuall CD, I convert it to ISO file with ISOBUSTER), so far im still playing with cd1 , so i have no idea how... because im pretty sure it will ask in the middle of the game to change to disk2 and so-on

Thanks

I think when it says change disk you click Esc and then go on file ->change disk -> then click on cd or iso then choose the next disk im not sure though.

WOW! Found the exact person I was looking for? Im trying to play my Legend of Dragoon game also. I tried using the cd and i also tried using an iso and bin that I made using MagicISO. The intro starts when I use ePSXE v1.52 but i cant do anything and the sound doesnt work?! SO which emulator are u using and how did you get the game to run?

Thank In Advance,

I reckon he's using the lastest one ePSXe 1.6.0 which u can find here
