-If you want to keep your OpenRCT2 install as clean as possible, you can extract the following files to the OpenRCT2 directories for a minimal install:
+As of 10 January 2016, OpenRCT2 needs some files from RCT2 in order to run. This page describes which files you need and where to retrieve them.
 
-## Normal Game
+## Two approaches
+You can either do a full install of RCT2 and point OpenRCT2 to its files, or only extract the files you want in order to conserve disk space. If you belong to the first group, you can now skip to _How to retrieve_.
+
+## Required and optional files
+_Note: this represents the needed files as of 10 January 2016._
 
 * Data:
- * g1.dat
+ * Required: g1.dat
  * Optional: CSS1.DAT and CSS2.DAT (sound effects)
  * Optional: CSS3.DAT - CSS9.DAT, CSS11.DAT - CSS15.DAT and CSS18.DAT - CSS46.DAT (music styles)
  * Optional: CSS17.DAT (title screen music)
+ * Optional: CSS17.DAT from RCT1, renamed to CSS50.DAT, which enables you to have the RCT1 title screen music.
 * ObjData:
- * The 772 default RCT2 objects. Easy to identify by sorting on date, since all 772 have a similar timestamp*.
+ * Required: The 772 default RCT2 objects. Easy to identify by sorting on date, since all 772 have a similar timestamp (usually from 2002 or 2003).
+ * Optional: The ObjData from Wacky Worlds, Time Twister and any custom content you like.
 * Scenarios:
- * If you use the OpenRCT2 title sequence, no scenarios are needed. Six Flags Magic Mountain.SC6 is needed for the RCT2 title sequence.
+ * Required: If you use the OpenRCT2 title sequence, no scenarios are needed. Six Flags Magic Mountain.SC6 is needed for the RCT2 title sequence.
+ * Optional: The standard scenarios from RCT2, and any custom scenarios you like. If you want the RCT1 scenarios, you can use the excellent conversions found here: http://www.mediafire.com/download/3cw47sd2wt3hues/ExactRCT1Recreations.zip
 * Tracks:
- * None are needed.
+ * Required: None.
 
-If you start OpenRCT2 for the first time _after_ you extract these files, it should detect them automatically.
+If you place those files in the OpenRCT2 folder, it should automatically detect them.
 
-\* This timestamp varies between media. Usually it is from 2002 or 2003.
+## How to retrieve
+The method to retrieve the files varies, as it depends on your operating system (Windows, OS X and various Linux distributions are supported) and your RCT2 media.
+* Disk version
+* GOG version
+* Steam version
+* Existing install
+* Mini game (follow these instructions if you don't own RCT2)

+### Mini Game 
+RollerCoaster Tycoon 2: Mini Game (RCT2:MG) is a demo released by Infogrames in 2002. It can be used to play OpenRCT2 if you don't own RCT2. However, there are some caveats:
+* It does not contain all ObjData. This will prevent many scenarios and saved games from opening.
+* It lacks most scenarios, including Six Flags Magic Mountain, so you can't use the original RCT2 title sequence - the OpenRCT2 will mostly work, however.
+* Its scenarios use a different checksum algorithm, which means they will be detected as corrupt. To use them, you must enable the "Allow loading files with incorrect checksums" option.
+
+#### Obtaining the Mini Game

 * [OpenRCT2.com website](https://openrct2.com/download-minigame),
 * [OpenRCT.net mirror](http://openrct2.eu/RCT2_Demo.exe),
 * [Mega.nz mirror](https://mega.nz/#!P8IgzJbB!wBIT90AXReO8VgrF53ulAHctrRWMsvmy0g1HPLv1T3M),

+* [Download Free Games mirror](http://www.download-free-games.com/dl/rollercoaster_tycoon2).
 
-* Similar to the normal game, g1.dat is required. Other than that, ALL Objdata from RCT2:MG is needed to run the game.
-
-* You can only use OpenRCT2 title sequence at the moment, using the Original RCT2 title sequence will crash the game.
-
-* To play scenarios provided with RCT2:MG, you **must** enable the "Allow loading files with incorrect checksums", since those scenarios have checksums that differ from those from the original game.
