Read or search through this forum to see if you can find the command line for an emulator. I have seen it in the past few months.
I am not sure if it will work the same, but you change the name of the emulator to XBMC and change the name of the ROM to your movie.
This will have to be done for each movie.
I am a dinosaur. I stuck with Evox for years. When the new MC360 skin came out, I converted to XBMC and am glad I did. You may want to change it to your default dash.
