For those games if you want to, you can also insert the extrapath line directly in the scummvm.ini, beneath the actual file path of that game, so for COMI it would look something like that:
CODE
[comi]
description=The Curse of Monkey Island
path=F:\emulators\scummvmx\games\comi\
extrapath=F:\emulators\scummvmx\games\comi\resource\
language=de
.
But there are those games that use more than one sub-folder (see:
http://wiki.scummvm....x.php/Datafiles ) and unless you want to merge the content of all folders into one, you can't launch them.
