Essential improvements[edit]


RollerCoaster Tycoon and its expansions have a number of available patches that are highly recommended. RCT STATION has uploaded all of these patches online, for download here. This will update RollerCoaster Tycoon to v1.08.187, Corkscrew Follies/Added Attractions to v1.10.026, and Loopy Landscapes v1.20.013.

The downloadable versions are already patched to the latest version.

Downloadable Content[edit]

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.

Widescreen resolution[edit]

By default, RollerCoaster Tycoon does not natively support widescreen resolutions. Using a hex editor, this can be changed.

Hack widescreen resolution


This hack only supports the following resolutions: 1280x720 (16:9), 1280x768 (15:9), 1280x1024 (5:4).
Be sure your monitor supports the resolution before editing rct.exe; The game will crash, otherwise.
This hack works with the original game, not the GOG/Steam/etc. version (the original retail release).
Higher resolutions could result in decreased performance, especially if there is a lot of attractions on screen.
  1. Download and install a hex editor, such as Be.HexEditor, or XVI32.
  2. Open the hex editor, then open rct.exe (found in the root of the installation folder)
  3. Search for the following string: 58 02 00 00 68 20 03 00 00
  4. 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
  5. Search for the string 20 03 00 00 c7 45 f4 58 02 00 00
  6. Change 20 03 to 00 05 (regardless of your screen resolution)
  7. Save and close the hex editor
  8. Run the game, start/load a save, click the save icon, and click on "Options"
  9. Select the 800x600 resolution to enable the resolution you hacked in

Issues fixed[edit]

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

Compatibility modes[edit]

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 XP SP2 or Windows XP SP3 compatibility mode from the Compatibility tab.

Desktop composition[edit]

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[edit]

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).
