turbografx turbo engine

i have a collection of turbografx roms i am trying to use in gameex. i find turbo engine to work well with them but i cant get it to work in gameex

i found that this is suposed to be the comand line

* Added command line support. The syntax is:
 
  "TurboEngine [--fullscreen] path_to_rom.[bin,pce,zip,7z,cue,iso]"

i cant figure out how that should go into gameex

here is a url to the emulator    http://aamirm.hacking-cult.org/www/turbo.html

thanks for any help.
