andreyua: try to create a bat file if you need a axecute something with parameters i.e create mess.bat file and write in it:
now select this bat file as emulator exeutable file.
If you need include a changeable romname in parameters chain then write it as %1
i dont know what doing all this parameters (writen by you) but with bat file it should be executed correctly
please read https://forum.team-mediaportal.com/my-emulators-247/emulator-configurations-44459/index4.html topic who could help understand this.
