A Modern Diablo II Version Switcher (Contains: Singling/Alpaca)

Description / History

Cactus started out as just a simple application that allowed you to easily and efficiently Time Travel between every version of Diablo II that ever came out, while maximizing disk space and enabling full character isolation between versions. However, even though Cactus itself still is just that, the Cactus Repository has evolved to become a centralized and historical archive, that aims to preserve every single Diablo II version that exists (Including the 1.07 Beta). Cactus is a complete rewrite from scratch of my previous application called: Bliss Version Switcher. However, since Cactus is written in C#, it behaves as a native Windows application and allows it to integrate natively with the system. On the other hand, Bliss Version Switcher was written in Java and thus there were many limitations that lead to the Cactus rewrite.

This repository also includes several other utilities that I have either created or collected, which can help you play Vanilla Diablo II better. All Cactus Platforms for versions below 1.12 already include the fix for removing the CD requirement (Blizzard already removed this requirement for versions 1.12+). Singling provides only non-gameplay modifications, things like CPU fixes, Ladder Runewords, Multiple Instances, Hardcore Character Creation, Faster LAN Creation/Joining, Etc. Alpaca provides an improved and stabilized Infinite Stash Mod for 1.13d on Classic and Expansion, and is stable for LAN play. Lastly, a few renderers are included to improve video compatibility, cnc-ddraw and glidewrapper. The choice is yours for how you want to play.

Cactus requires a purchased copy of Diablo II from Blizzard in order to have all of the game assets stored in the MPQs. Once you have these, they will be re-used for all Cactus Platforms.

For further information, please read the documentation below for anything you are interested in exploring. If you wish to find players to play with, or just to hang out and talk about Diablo II Single Player, please join the Cactus Discord by clicking the link at the top of this page!

Cactus Repository

The following opt-in modifications and utilities are available in this repository:

Singling

A collection of non-gameplay modifications and fixes in order to improve the Vanilla Diablo II Single Player Experience.

To use Singling, simply copy the Singling files for the version you want to play from the 2. Singling/1. Files folder, and replace the ones for the equivalent version in your Platforms directory. To revert, use the files in 2. Singling/2. Stock instead.

Alpaca

Alpaca is an Infinite Stash for Diablo II: 1.13d that was based off Yohann Nicolas' PlugY 11.02. It has been massively refactored, stabilized, and has full support for Diablo II Classic. All previous PlugY bugs that were related to Multiplayer / LAN have also been fixed.

To use Alpaca, simply copy all the files in the 3. Alpaca folder into your 1.13d Platform. You can then launch Diablo II with Alpaca.exe rather than Game.exe. In order to have the best experience, please install Singling as well.

Renderers

Cactus includes two alternative renderers for Diablo II which can help you run the game on newer systems with a higher resolution (not a higher internal resolution), and the ability to use shaders to upscale the quality of the graphics in the game (cnc-ddraw). Both of these renderers are automatically included as part of the Cactus Base Installation. cnc-ddraw should be used in versions of Diablo II older than 1.14, and glidewrapper should be used for any newer versions. Please read the README-RENDERERS for further explanation on this, for information on how to set them up, or for any known technical limitations.

• cnc-ddraw - This renderer reimplements the DirectDraw API for GDI, OpenGL, and Direct 3D to improve compatibility with Windows XP - 10, and Wine (Linux). This renderer also supports the use of custom shaders - which will allow you to upscale the game so it looks a lot better - and even provides hotkeys (such as [Alt] + [Enter]) to switch between full screen and window mode.

• GlideWrapper - A simple glide to opengl wrapper which will allow you to enable Perspective mode.

Installation Instructions

Install Cactus And Prepare MPQs

This section will help you install Cactus to the correct location and also help you fix your MPQs so that they are compatible with the older versions of Diablo II.

1. Copy all of the files in the 1. Files folder into your Diablo II root folder.
2. Run the FIX_MPQS_RUN_AS_ADMIN.bat inside the MpqFixer that you copied, as Administrator. This will fix your MPQ files so that they work with the older versions of the game.

Adding/Running A Platform

1. Run Cactus.exe
2. Click Add
3. Type in the name of the Platform you want to run. This should match a folder in the Platforms folder. (Example: If you want to run 1.09b, type 1.09b).
4. Enter the path to the executable you want to launch in your Diablo II root folder. Cactus copies all of the files from the Platforms/[NAME] folder to the Diablo II root folder, so most of your entries will have identical paths (Example: D:\Games\Diablo II\Game.exe). Do not put something that points to an executable in the Platforms folder since that will not work and will give you an Object reference not set to an instance of an object error. The executable has to be in the root of the Diablo II folder as described above.
5. Enter the Flags you want (Example: -ns)
6. Make sure Expansion is selected (Unless you are playing 1.00-1.06b or didn't purchase Lord of Destruction).
7. Click Add.
8. Select your newly added Platform and press Launch.

The game should start. If you are having video issues, please make sure you have read the README-RENDERERS and ensure that it was configured properly.

Moving Cactus To A New Computer

If you want to move all of your Platforms, Characters, and Diablo II folder to another machine, you will need to:

1. Copy your entire Diablo II folder to your new machine.
2. Edit the Entries.json file and change the Path for all of your entries so that it now has the Path on your new machine.
   • The Base Directory for all Paths need to match. The exes can be different.
     • GOOD: D:\Games\Diablo II\Game.exe and D:\Games\Diablo II\Alpaca.exe.
     • BAD: D:\Games\Diablo II\Game.exe and D:\Diablo Immortal For PC\Game.exe.
3. Open Cactus and edit the Last Ran Platform.
4. Uncheck the Last Ran box and Click Edit.
5. Now Launch whatever Platform you want.

Unchecking the Last Ran box will cause Cactus to reconfigure itself (Including registry locations).

Updating Files In The Platforms folder

If you update any files in your Platforms folder, then uncheck the Last Ran box from the corresponding platform, and run it again. This will cause Cactus to re-install the files with the new ones.
