10. What is ResidualVM?

---

ResidualVM is a game engine reimplementation that allows you to play 3D adventure games such as Grim Fandango, Escape from Monkey Island and Myst III.

ResidualVM utilizes OpenGL for 3D graphics hardware acceleration. A software renderer is also included for machines without hardware OpenGL.

2. Current state

---

At this point ResidualVM is fit for normal use, when playing supported games, it is however worth noting that you should still save early, and save often, as problems or dead-ends might still exist. (Grim Fandango itself originally had a few unintentional ways to get the game stuck).

2.1. Which games does ResidualVM support?

Currently ResidualVM supports Grim Fandango and Escape From Monkey Island, as well Myst III.

2.1.1. GrimE-games support

Game	Status
Grim Fandango	Completable with glitches
Grim Fandango (demo)	Completable with glitches
Escape From Monkey Island	Completable with glitches
Escape From Monkey Island (demo)	Completable with glitches
Escape From Monkey Island (PS2)	Untested

2.1.2. Other games support

Game	Status
Myst III Exile	Completable with glitches

Specifics can be found at http://www.residualvm.org/compatibility/

For more information, see the page on ResidualVM at the wiki page: http://wiki.residualvm.org/

3. Running GrimE games

---

3.1. Required files

For both Grim Fandango and Escape from Monkey Island, you will need the original game files as well as the official update patch.

3.1.1. Grim Fandango

You will need to copy the data files from your Grim Fandango CDs into one directory. Specifically, you'll need:

• All of the .LAB files from both CDs
• A copy of the Grim Fandango 1.01 update EXE The patch can be downloaded from: http://demos.residualvm.org/patches/gfupd101.exe

3.1.2. Escape from Monkey Island

You will need to copy the data files from your Escape from Monkey Island CDs into one directory. Specifically, you'll need:

• All of the .M4B files from both CDs Note: The file voiceAll.m4b is repeated on both CDs. Use the copy from the first CD, it contains all of the required voice data
• The Textures directory, combined from both CDs. When copying, rename the FullMonkeyMap.imt files to FullMonkeyMap1.imt and FullMonkeyMap2.imt from CDs 1 and 2 respectively.
• The Movies directory from each CD
• A copy of the Escape from Monkey Monkey Island update EXE You will need a patch specific to the EMI version you're using:
• "EFMI Installer" if you have the Mac version of EMI.

English	http://demos.residualvm.org/patches/MonkeyUpdate.exe
Portuguese	http://demos.residualvm.org/patches/MonkeyUpdate_BRZ.exe
German	http://demos.residualvm.org/patches/MonkeyUpdate_DEU.exe
Spanish	http://demos.residualvm.org/patches/MonkeyUpdate_ESP.exe
French	http://demos.residualvm.org/patches/MonkeyUpdate_FRA.exe
Italian	http://demos.residualvm.org/patches/MonkeyUpdate_ITA.exe

3.1.3. Escape from Monkey Island (PS2)

You will need to copy the data files from your Escape from Monkey Island DVD into one directory. Specifically, you'll need:

• All of the m4b files from the DVD
• The Videos, demos, jambalay, lucre, melee and monkey directores

3.2. Running the game

1. Prepare the game directory as specified above
2. Open ResidualVM
3. Choose "Add Game"
4. Select the folder you created in Step 1
5. Click Start

If you want to play with software-rendering, see the configuration-section below, or use the ingame settings to disable 3D Acceleration.

When launching the game for the first time, ResidualVM will perform a full integrity check of your game data files. This can take a bit of time, but it will not happen again on successive runs. This prevents bugs from incompatible game data, and helps us to find game variants that we're not aware of.

3.3. Default Keyboard-settings

Key	Binding
e,u,p,i	Examine, Use, Pickup, Inventory
Arrow keys	Movement
Shift	Hold to run
Enter	Selects items in inventory, conversation, etc
Escape	Skips cutscenes, exits certain screens
.	Skips dialogue
q	Exit Dialog Menu
Ctrl + c	Force Quit (from command-line)
Alt + x	Quit (ingame)
Alt + enter	Switch between windowed-mode and fullscreen
F1	Menu

3.4. Joystick/gamepad support

If you want to use a joystick or gamepad for navigation, the joystick support of the engine needs to be enabled using one of the following two options:

• start residualvm with "--joystick" parameter
• add "joystick_num=0" to the "[residualvm]" section of the configuration file (see section 5.1. how to find the file)

4. Running Myst III

---

4.1. Required files

You will need these elements from your game CDs or DVD :

• M3Data directory
• Data directory
• The original game executable (Windows or Mac)
• The menu language file 'language.m3u', or '[LANGUAGE].m3u' (DVD only)

When using the CD version, you will need to merge the 'Data' directories from all four discs. Playing directly from the CDs is not supported.

It is recommended to apply the most recent official update for your game language. The DVD version comes fully updated. The updates can be downloaded from http://demos.residualvm.org/patches/.

ResidualVM will accept either the Windows executable (M3.exe) or the Mac executable. Some Windows executables are encrypted using SafeDisc. ResidualVM cannot read the required data from those, and will refuse to launch the game. Since the updated executables are not encrypted, please use the executable from the official update corresponding to your game language instead.

The DVD version is multilingual, you can change the in-game language from the game menu. However, you must choose the language of the menus by copying the appropriate files. You have to copy M3.exe and the menu language file both from your chosen language folder on the disc. The menu language file can be named 'language.m3u' or '[LANGUAGE].m3u' depending on the release. It should be copied to the 'M3Data/TEXT' folder.

The language of the original executable and of the datafiles you use must match. You must not mix the files from different versions of the game.

The required files must be organized in the following manner to be recognized:

├── bin
│   └── M3.exe
├── Data
│   └── *.m3a
└── M3Data
    └── Various files and folders (including the DVD version's menu language file)

4.2. Running the game

1. Copy the necessary files to a folder on your Hard Drive
2. Open ResidualVM
3. Choose "Add Game"
4. Select the folder you created in step 1
5. Click Start

4.3. Input controls

The mouse is used to look around and interact with the ages.

Available keyboard shortcuts:

Key	Binding
Escape	Original Myst III Menu
Ctrl + F5	ResidualVM Menu
Space	Skip cutscenes, interact
Ctrl + c	Force Quit (from command-line)
Ctrl + q	Quit (ingame)

5. Configuration

---

Currently, not all the settings for ResidualVM are available through the GUI, if you have problems with getting anything to work, first try to pass the settings from the command line, then, if that doesn't work, try to change your configuration file manually.

5.1. Location of configuration file

By default, the configuration file is saved in, and loaded from:

Operating System	Location
Windows Vista/7/8	\Users\username\AppData\Roaming\ResidualVM\residualvm.ini
Windows 2000/XP	\Documents and Settings\username\Application Data\ResidualVM\residualvm.ini
Unix	~/.residualvmrc
Mac OS X	~/Library/Preferences/ResidualVM Preferences
Others	residualvm.ini in the current directory

5.2. Interesting settings for GrimE games

The following settings are currently available in the config-file, however some of them might not work with your current build. And some of them might make ResidualVM crash, or behave in weird ways.

Setting	Values	Effect
show_fps	[true/false]	If true, then ResidualVM will show the current FPS-rate, while you play.
last_set	[set-name]	The set you were last on, ResidualVM will try to continue from there.
last_save	[save-number]	The save you last saved, ResidualVM will have that selected the next time you try to load a game.
use_arb_shaders	[true/false]	If true, and if you are using the OpenGL renderer ResidualVM will use ARB shaders. While fast they may be incompatible with some graphics drivers.
fullscreen_res	[desktop/WWWxHHH]	If set to "desktop" (the default), ResidualVM will use your desktop resolution in fullscreen mode. If set to a resolution such as "640x480" or "1280x720", that resolution will be used.

6. Troubleshooting, Known Bugs, Issues

---

Grim Fandango had a few issues when it came out, and a few new and exciting issues when you try to run it on newer hardware. Some of these have been fixed in ResidualVM, but ResidualVM itself also has a few new issues that we know about: http://github.com/residualvm/residualvm/blob/master/KNOWN_BUGS

Look below for help with these issues, and if you can't find help here, try either the forums at our homepage, or IRC: #residualvm at freenode.

6.1. I played a bit, but can't start a new game!

This is because the last save and visited scene is stored in your configuration file, either delete grim-fandango from the ResidualVM-menu, and re-add it, or go to your configuration file, and clean out the last-save and last-set entries.

6.2. My Save Games don't work any more

Did you recently update to a newer build of ResidualVM? ResidualVM is still a work in progress, which means that the save format might change between builds. While attempts are made to keep save file compatibility, this isn't always possible.

6.3. In fullscreen mode, the picture is stretched!

This is know issue, in future versions it will be resolved.

7. Debugging

---

WARNING: This section contains information about the various tools that are included for debugging ResidualVM, this should not be necessary for normal play at all! However, the curious might like to know how to access these tool. Please use at your own risk!
