Hey again, guys.
I've managed to edit speech.info correctly, without removing the voice overs, using HEX editor (don't know why it didn't work earlier). But, speech.info doesn't edit any text in the original SMI version OR the dialouge choices in the new version (I mean, like, if we change Guybrush's line, the choice line will still be the same, though Guybrush will say other things). Editing original text files kind of helped, but voice overs disappear for any edited in the original monkey game line. Does anybody know how to fix this?
