Do you mean that in order to work out which part of which data file should be hacked/edited, I'd have to translate the original bundled interpreter into disassembly? Crumbs. Sounds like too much work already. =[
And while ScummVM is capable of disabling code protection, it does not do it to all games (original floppy games for instance will still expect you to enter a specific code, and I believe games by Coktel Vision and possibly others will also still tell you to input a code), hence the need for a script hack. Most cracked/scene releases I've seen of Lucasfilm/LucasArts games from this early era usually crack the DOS executable only, something that's meaningless to ScummVM.
