RCT1 Hacked Save Games



August 15, 2014: This site was originally hosted by GameSpy under the StrategyPlanet division and as a subsite of the RCTUK site. That was back in the early days of the internet (think: dial up modem at 1200 baud) and the early days of RCT. That server had been locked for several years and has finally been taken completely offline. The good news is that this site is now hosted by an RCT fan(atic)! Even better news is that there is still activity in the community for making enhancements to and reproductions of the game.

Old News Items

The popular simulation games RollercoasterTycoon® 1, 2 and 3 were written (and copyrighted) by Chris Sawyer and/or Frontier and distributed by Atari (..Infogrames..Hasbro Interactive..Microprose). The purpose of this site is to compile technical information about the game which has been determined by its fans. The goal is to promote the creation of enhancements and additions to the game. Under no circumstances should this information, or any of the utility programs, be used in a manner which would interfere with the commercial activities of the game's creators or distributor.


There are some residuals from old projects...check the Beta Versions Page for what's available.
