I looked in my games folder and it is empty! I didn't delete them - but they are gone. Not sure what happened. I don't even remember the default games besides word mole ...
Do the opposite of what you did to get rid of them. And Yes you did tinker with something that your not saying so whatever you did,stop doing it in the future.
Mine came with brickbreaker and word mole. Both not worth reloading in my opinion, but to each there own. I'm sure if you reload a new os you will get your games back. Easier yet find new ones on th CB downloads page. Good luck
