Comment (by i30817):

 If I'm understanding the issue correctly, you can use the command line
 options -a and -p to add multiple games with much fewer false positives
 and without having to choose.

 The reason is that the command line interface is forced to choose a item,
 and when the first item is already chosen (for a not aleatory example,
 'unknown director game') it will almost always chose the next one (which
 is usually the one where at least the filename being checked exists even
 if the checksums isn't exactly right).

 This saves a LOT of trouble with 'unknown ags' or 'unknown director'
 games, even before you realize it's much faster (it isn't recurring over
 the whole directory tree. Most people have their games intended to be at
 the same level or in a few separate theme dirs and you can scan this way
 way way faster than the gui).

 I use (Linux):

 rm -f add.log;find /absolutepathtonext/ScummVM
 /absolutepathtonext/ScummVM_Text/ /absolutepathtonext/ScummVM_AGS/
 -mindepth 1 -maxdepth 1 -type d -exec echo "{}" >> add.log \; -exec
 scummvm -a -p"{}" >> add.log \;


 saving the log is to search for dirs inside the base dirs (the three dirs
 called /absolutepathtonext/ScummVM that scan no games, you can search for
 'added 0').

 This is usually because you messed up setting up the files and they're
 more nested inside the dir than you need to scan it in a single pass
 without recursion.


 Note that avoiding recursion saves a lot of time with false positives
 because some engines can add some false positives for subdirs for the same
 game (which don't work). Ultima, toonstruck, Crusader engines are some of
 them.
