Problem with DC .cdi

For a few days I have been trying to make a .cdi file that was made with bootdreams work with nulldc. The problem is nulldc will recognize the .cdi, but when i load it it goes to the DC menu screen and if I hit play it will do the DC logo and go back to the menu screen.

I have tried making the .cdi with the .bin/cue, iso and a plain file of it, but they all do the same load to menu screen.

Try alternating the plugins.

Pretty much only four combos:
1.) Null Video/Sound
2.) Chankast Video/Sound
3.) Null Video/ Chankast Sound
4.) Chankast Video/ Null sound

Keep in mind that some official games don't work properly, let alone homebrew emulators, or games. If it is homebrew, the only option may be an actual Dreamcast.
