Not only that, in ScummVM, game data is *always* read-only :-). So  
yeah, I guessed it, it's pretty obvious :-). And I know we'll have to  
implement mirroring for this reason (as we have done in other engines,  
e.g. for HE SCUMM games), but I don't want to do it without having a  
test case.

Relying on external storage is fine, and should work already with the  
patch. What is not implemented is indeed using the "default" (read- 
only) version shipped as part of the game data...

Are there demo versions of these holye games and do they also use an  
external config file with a default set of settings? That would help  
with testing. Otherwise, I only have the PQ, SQ, KQ and LSL series as  
full versions... Do any of those use this "feature"?
