Tested this method with Need for speed, Monopoly, Asphalt5 and Sim3
It works flawlessly and now I do not need the game folders in my Opt

Saved lots of MBs, the more games you've got the more you saved

for Asphalt5 you'll need to make a save folder

mkdir -p /home/user/webos/gamesave
ln -s /home/user/webos/gamesave /media/internal
