Command Line Issue

Using 1.2, I’m having issues feeding the rom in using the command line. It will start up RetroArch with the correct core, but doesn’t load the game. I have it working on a different machine using the old version, and cannot figure out what’s going on. I should mention that I’m using EmulationStation as the frontend, which replaces the %ROM_RAW% with the full path to the ROM. Here’s the command I’m using right now:

C:/Users/arcade/ROMS/RetroArch/retroarch.exe -L C:/Users/arcade/ROMS/RetroArch/cores/fceumm_libretro.dll -f “%ROM_RAW%”

Can anyone tell me what I’m doing wrong?
