Yes, the GM:S bytecode format seemed to have changed between versions. This will take a bit of an overhaul to fix... Thanks for the report!

Looks like both the Flowey the Decompiler guy and someone else are also working on reversing the updated Bytecode https://gist.github.com/PoroCYon/45f947d576f715de3a4d

@danne2 FYI, my implementation is already functional! >:D

0x000000:
    self.demona = "Greetings."
    self.demonb = "You have made yourself completely clear."
    self.demonc = "Understood."
    self.demond = "I, your humble servant, will follow you to the utmost..."
    exit
