My problem is that this config file only works for the folder in which my rom is directly placed.

To give you a better understanding what I mean, here is an example: My folder structure looks like that:

Games

• Gameboy
• • Artworks
• • Savegames
• • • (Name of the game).srm
• • • (Name of the game).state
• • Roms
• • • Asterix
• • • • Asterix.gb
• • • Pokemon Red
• • • • Pokemon Red.gb
• Gameboy Color
• Gameboy Advance
• and so on

As you see I don't have one savegame folder for all savegames, but separated by platforms.
My first attempt was to use the core-override-config-file to set an individual savegame path for each platform.
But then I realized that there are cores like Gambatte which are used for two or more platforms (GB & GBC).
So this won't work, since I can set only one savegame path per core and I would need two savegame paths in this case.
Then I discoverd the directory-override-config-option which is actually exactly what I need in this case.
But the problem is that the "directory" is limited on the folder in which my rom is directly placed.
So instead creating a config file which counts for all contents of the "Roms" folder, it only creates a config file which counts for the folder "Asterix" since this is the next higher folder of the content which I've loaded.
The name of the config file would be "Asterix.cfg"

What I need is a config file named like "Z-Games-Gameboy-Roms.cfg", which counts for all contents in the directory "Z:\Games\Gameboy\Roms"

This would make this override option much more useful in my opinion.
