Essential improvements


RollerCoaster Tycoon has a number of patches available from Atari's FTP server. Additionally, Corkscrew Follies and Loopy Landscapes each have one patch. These will update RollerCoaster Tycoon to v1.08.187, Corkscrew Follies/Added Attractions to v1.10.026, and Loopy Landscapes v1.20.013.

The 2003 Deluxe release, as well as all downloadable versions are already patched to the latest version.

Downloadable Content

There are two official roller coaster collection downloads from Chris Sawyer, both available via his website. While the "Cat" collection can be used in any version of the game, the "Phobia" collection can only be used in conjunction with games that have either the Corkscrew Follies/Added Attractions or Loopy Landscapes expansion packs.

Play without a CD (Loopy Landscapes)

Copy files to disk and edit registry files[3]
  1. Copy all files from the "Data" folder on the CD-ROM to the "Data" folder in the game directory. Overwriting is not necessary.
  2. In the Registry Editor, go to the HKEY_LOCAL_MACHINE\Software\Fish Technology Group\Rollercoaster Tycoon Setup key for 32-bit systems or HKEY_LOCAL_MACHINE\Software\WOW6432Node\Fish Technology Group\Rollercoaster Tycoon Setup key for 64-bit systems.
  3. Change the SetupPath string value to point to your game directory (copying the Path value is the easiest way).

Widescreen resolution

This hack only supports the following resolutions: 1280x720 (16:9), 1280x768 (15:9), 1280x1024 (5:4).
This hack works with the original retail release, not the versions.[citation needed]
Hack widescreen resolution[citation needed]
  1. Open rct.exe with a hex editor such as HxD
  2. Search for the following string: 58 02 00 00 68 20 03 00 00
  3. Depending on the resolution you choose, edit the string accordingly
    1. 1280x720 (16:9): Change 58 02 to D0 02
    2. 1280x768 (15:9): Change 58 02 to 00 03
    3. 1280x1024 (5:4): Change 58 02 to 00 04
  4. Search for the string 20 03 00 00 c7 45 f4 58 02 00 00
  5. Change 20 03 to 00 05 (regardless of your screen resolution)
  6. Save and close the hex editor
  7. Run the game, start/load a save, click the save icon, and click on "Options"
  8. Select the 800x600 resolution to enable the resolution you hacked in


Higher resolutions could result in decreased performance, especially if there is a lot of attractions on screen.

Issues fixed

The downloadable versions are already patched to be compatible with modern systems. The fixes below are for the original release.

Compatibility modes

Setting the game to run in compatibility mode can help fix many issues with launching and playing the game. To do this, right-click the .exe, open Properties and set the game to run in Windows 98 / Windows ME, Windows XP SP2, or Windows XP SP3 compatibility mode from the Compatibility tab.

Desktop composition

Some problems can be caused in Windows 7 and Windows Vista by having desktop composition enabled. To turn this off, check the 'Disable desktop composition' option from the Compatibility menu (right-click .exe > Properties > Compatibility).

Dialog boxes not opening/unable to save

Running RollerCoaster Tycoon with visual themes enabled can prevent the open/save dialog box from opening. To fix this, check the 'Disable visual themes' option from the Compatibility menu (right-click .exe > Properties > Compatibility).

Another save game issue can be caused by not running the game as an Administrator. To fix this, check the 'Run this program as an administrator' option from the Compatibility menu (right-click .exe > Properties > Compatibility).

  1. SafeDisc retail DRM does not work on Windows 10[1] or Windows 11 and is disabled by default on Windows Vista, Windows 7, Windows 8, and Windows 8.1 when the KB3086255 update is installed.[2]
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/285310/ in addition to or instead of this directory. The app ID (285310) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
  3. When running this game without elevated privileges (Run as administrator option), write operations against a location below %PROGRAMFILES%, %PROGRAMDATA%, or %WINDIR% might be redirected to %LOCALAPPDATA%\VirtualStore on Windows Vista and later (more details).
