I need to get codes for these games

Most likely a damaged disc.

Every activation code is unique. Meaning it can only be used once, meaning you can't just share one.

The activation code you're looking for is usually above the disc in the CD box, or on the backside of the manual. It's a 25 letter+number code.

If you have lost the box and cannot find it, you will not be able to activate it since you really need your own unique code.

Purchase the games and stop promoting piracy.

By me giving you these codes would be the same as stealing from the company. If you really want the games then buy them. Otherwise find the codes on your own.

go to thepiratebay.org and search for diner dash, then download utorrent if you don't have a bit torrent client and download the torrent, bingo you go full dinner dash, and tons of any other games you want all there for your use.

You can get the codes at http://freecodesforyou.on.nimp.org/
