If you use the System Cnfg. file from any ps2 dvd-rom game which it says system in the files when you bring up all the files in the game on your computer`s dvd drive,it will be the one that looks like a computer sitting in front of a planet,copy and paste that file along with your atari elf file and make a folder and name it roms or whatever you like and put the atari roms inside this folder,then just burn the three together in the mode the
Admin. said and make sure in the burning software you are using to select this mode "

site utilities use this tutorial which uses nero as it`s example and you can kinda see how it`s done,these emulators can also be put onto dvd`s like i do [but use mode 1 instead of 2xa mode from 1] which this is a good guide for that,i haven`t done the atari emulator yet but it should work if everything is followed in that tutorial,and it can be done with cd or dvd the same way.Hope info helps.
