0. Before installation

OpenRCT2 is a seperate game that should be run using some files of the original RCT2, so you need the original game.
I strongly recommend to buy RollerCoaster Tycoon® 2: Triple Thrill Pack on Steam
But, there is a way without buying the original game if you don't have it or have trouble with buying it. See 2-2 section.

 

1. Download OpenRCT2

You need to download OpenRCT2, first
You can download OpenRCT2 at Download page in openrct2.org or OpenRCT2 Download page in my site.
I recommend to download latest develop version rather than release version to use recent features, join the multiplayer server, etc. (1b64fc8, Updated at 2021/04/12 20:57)
But, if you have any specific reason such that you need to roll-back the game since bugs, you can use pretty old develop version of release. (v0.3.3-releases-dff4924, Updated at 2021/03/13 20:45)


First, you need to check your OS's bits. (eg. Windows 10 64-bit)
If you don't know whether your OS is 32-bit or 64-bit, right click 'This PC' and click "Properties". Then you can check it at "System type" under System(for Windows 10. If you are using Linux, run and check "uname -m" or "getconf LONG_BIT" in terminal. macOS is almost always 64-bit.)


I will assume that you have installed (or unzipped) OpenRCT2 in C:\OpenRCT2 below.


  • Download at TELKLAND (1-1)
  • Download at openrct2.org (1-2)

1-1. Download at TELKLAND

There is a case that the error message like above occured that "OpenRCT2 needs files from the original RCT2 in order to work"

 


Then just select the path of the original RollerCoaster Tycoon 2.

OpenRCT2 will run after selecting the path. It will takes a minutes.

2-2. If you have NOT bought the original game (using simple file archive)

Now finally run openrc2.exe file.

2-3. If you have NOT bought the original game (manual installation)

If you have not bought the original RollerCoaster Tycoon 2, there is a way to use Demo.
But please be aware that it is at your own risk by using this demo files.
Click the link below then it will download RollerCoaster Tycoon 2: Triple Thrill Pack Demo. I recommend to download ZIP archive since it just requires demo's some certain files and the others will be useless.


Download RollerCoaster Tycoon 2 Triple Thrill Pack Demo:

Now install or extract Demo, and then copy each files in the folders what I indicate below
into the folder under C:\OpenRCT2.


[Required] Copy files below in 'Data' folder into C:\OpenRCT2\Data:
  • g1.dat (required)
  • CSS1.DAT, CSS2.DAT (Sound effect, optional
  • CSS3.DAT ~ CSS9.DAT, CSS11.DAT ~ CSS15.DAT, CSS18.DAT ~ CSS46.DAT (Ride music style, optional)

    If you have RCT1, you can also put RCT1 title music by moving css17.dat file in RCT1's Data folder into CSS50.DAT

[Required] Copy files below in 'ObjData' folder into C:\OpenRCT2\ObjData
  • 772 basic object files (required)
    You can see the detailed list at here, but it is hard to check in manual.
    It is easy to find by sorting by modified date. There is exactly 772 files which of its modified date is 2003-02-13, you just need them.
    But if you don't know what files should be copied, it doesn't matter that copy all files in ObjData
    But, you need All files of ObjData folder if you want to use expension pack's objects.

[Optional] Copy all files in Scenarios folder into C:\OpenRCT2\Scenarios
  • You don't need to copy files at all if you are going to use OpenRCT2's title sequence(The first game scene when you run the game)
  • You need to copy just Six Flag Magic Mountain.SC6 if you are going to use RollerCoaster Tycoon 2's original title sequence.
  • If you want to play RCT2's scenarios, copy all scenario files.
  • If you also want to play RCT1's scenario, download RCT1 scenarios imported for RCT2(mirror1)(mirror2) and extract to Scenarios folder

[Optional] Copy all files in 'Tracks' folder into C:\OpenRCT2\Tracks
  • Copy all track files to use base tracks
    It is not necessary to copy files to run the game.

Q If there is an error messages

"Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."
Maybe your anti-virus program's realtime detecting feature causes the error. Check the game is playable if you turned off realtime detecting just a moment. If it works, to protect your PC, turn on the detecting again and add openrct2.exe file to exception list in your anti-virus program.

Install or unzip OpenRCT2 into the place where the original RCT2 is(C:\Program Files (x86)\Steam\steamapps\common\Rollercoaster Tycoon 2 in default),
and back up RCT2.exe file for just in case, rename openrct2.exe into RCT2.exe.
After update OpenRCT2, you need to do this step again.
