I'd suggest that you move all your games from their current location to /dev_hdd0/GAMES and go on with it.
You can do it easily from multiMAN's filemanager by selecting your GAMEZ folder in the LEFT pane, open /dev_hdd0 in the right pane and press [SELECT]+[O] to move GAMEZ to the root of the /dev_hdd0... then select it and press [SELECT]-[X] to rename it.
If you don't rename it - it will still work (but if you backup new games they'll go into the folder set in the .ini).
Or you can use blackbox FTP to do the same from your PC.
