+* libs\SDL2\[i686/x86_64]...\bin
+* libs\SDL2_mixer\[i686/x86_64]...\bin
+
+and don't forget to build r_opengl.dll for srb2dd.

+Windows Install Builder
+for SRB2
+
+This installer is much like the 7-Zip self-extracting archive, except
+this allows for scripting the post-install step.
+
+This also allows for some light customization, including dialog messages
+and program shortcuts.
+
+The included install scripts manage the game data location depending on the
+install location -- if installed in Program Files or AppData\Local, the
+game data location is set to %UserProfile%\SRB2.
+
+Program shortcuts are also added, as well as an uninstaller that
+will remove the icons and also selectively uninstall the core game files.
+The uninstaller gives you the option to preserve your game data and mods.
+
+How to Use
+----------
+
+1. Zip up the install contents in 7z format.
+    * ALL FILES MUST BE IN THE `new-install/` ARCHIVE SUBFOLDER, OR THE
+      POST-INSTALL SCRIPT WILL NOT WORK!
+    * Make sure you are using the LZMA2 algorithm, which is 7-Zip's default.
+
+2. Copy the 7z archive to this folder using the following names:
+    * Installer.7z     - 32-bit full installer
+    * Patch.7z         - 32-bit patch
+    * Installer_x64.7z - 64-bit full installer
+    * Patch_x64.7z     - 64-bit patch
+
+3. Set the text in VersionFilename.txt to the version identifier for the
+   installer's filename.
+    * e.g., v2121 for v2.1.21, from "SRB2-v2121-Installer.exe"
+    * Also look through sfx/config-installer.txt and sfx/config-patch.txt
+      and update the version strings. Templating is TODO.
+
+4. Run BuildInstaller.bat [7z.exe install path]
+    * First argument is the path to 7z.exe. If this is not specified, the
+      script will try to look for it in C:\Program Files [(x86)]
+    * This script will automatically add the install scripts to each
+      installer.

+SRB2 Install Instructions
+
+1. Move every file from the "new-install" folder to this main install folder.
+
+2. DELETE "staging.bat" and "staging.txt"! These can mess up your installation if run by accident!
+
+3. Optionally, create a folder in your user profile named "SRB2". This is where your game data and addons may live. For example,
+
+	C:\Users\[User]\SRB2
+
+4. Run the game! Double-click srb2win.exe -- or see if you have Start Menu icons under "Sonic Robo Blast 2".
