CBox fmp loader is WIP, use FE.
Place the tng with the others.
Cutscene tool found
here.
Normally I'd say that you can open the fsc with notepad (it's just a text document, like a tng), copy the contents and place it in the appropriate cutscene in the script.bin using CBox since it was made to handle the cutscenes properly, but to get the right stuff in the right modes would be going through too much trouble, even for me.
