command line question

[JJXB]

i'm configuring a shortcut for kura so she can just double click and play without dealing with any of the plugins etc and here's how it currently goes:

C:\Emu\PSX\EPSXE\ePSXe.exe -nogui -cdrom I -loadmemc1 dawn.mcr

but it claims -cdrom is invalid when it is in the help file. i'm using 1.6.0 by the way so the -cdrom command may not be there anymore but is there any alternative to that command line to launch straight from cd/virtual drive? (i won't move the image file to the epsxe directory just to be able to use the -loadiso command either)
