Any cheat codes are available?

[Bark933]

Old cheat codes are still valid?

Like that;

Picture guest
Enter "Chris Sawyer" as a guest name to have them walk around and take pictures of your park.

I bought the game to play sandbox so i really could use a cheat code for money

This game is made using Roller Coaster Tycoon 2, so there's good chance that the "cheats" for RCT 2 work in this game.

That being said, they aren't really cheats. However, you can use them to your advantage.

Chris Sawyer         Takes pictures of all the rides.
Simon Foster	     Draws pictures of all the rides.
John Wardley	     Thinks, ''Wow!'' all the time.
John Mace	     Pays twice as much for stuff.
Damon Hill           Drives his Go-Kart at double speed.
Mr. Bean             Drives his Go-Kart at half speed.
Katie Brayshaw       Waves at all your guests.
Melanie Warn	     Gets really happy and doesn't leave.
Andy Hine	     Shouts out gibberish after getting off rides.
Elissa White	     Loves the Intamin rides.
David Ellis	     Starts to describe all the rides.

Most of the names don't do much, but naming lots of peeps 'John Mace' will totally up your cash and making a horde of 'Melanie Warn' clones will send your park happiness rating through the roof!

You'll have troubles if you try to name everyone the same thing though. You have to mix it up a bit by rearranging the capital letters in people's names like this:

• John Mace
  
• jOhn Mace
  
• joHn Mace
  etc...

Don't know if these still work, but they should . Hopefully that helps!
