ScummVM README Last updated: 2002-04-15 Release version: 0.2.0 [CVS build] ------------------------------------------------------------------------ For more information, compatability lists, details on donating, the latest release, progress reports and more, please visit the ScummVM home page at: http://scummvm.sourceforge.net/ About: ------ ScummVM is an implementation of the SCUMM (Script Creation Utility for Maniac Mansion) engine used in various Lucas Arts games such as Monkey Island and Day of the Tentacle. At this time ScummVM should be considered ALPHA software, as it's still under heavy development. Be aware that while many games will work with few major bugs, crashes can happen. Also note that saved games can, and probably will, be incompatible between releases. Also ScummVM is capable of playing several non-SCUMM games, at the moment this includes Simon The Sorcerer. If you enjoy ScummVM feel free to donates using the PayPal button on the ScummVM homepage. Supported Games: ---------------- At the moment the following games have been reported to work, and should be playable to the end: Loom (256 color CD version) [Game: loomcd] Monkey Island 1 (CD version) [Game: monkey1] Monkey Island 2 [Game: monkey2] Indiana Jones And The Fate Of Atlantis [Game: atlantis] Day Of The Tentacle [Game: tentacle] Sam & Max [Game: samnmax] Simon The Sorcerer [Game: simon1dos or simon1win] The following games should load, but are not yet fully playable. If you want the latest updates on game compatibility, visit our website and view the compatibility chart. Zak McKraken (256 color FM Towns version) Indiana Jones and the Last Crusade (256 color version) Full Throttle The Dig The following games are SCUMM engine, but NOT supported by ScummVM (yet).

BeOS - ??? Dreamcast - ??? Known Bugs: ----------- This release has the following known bugs. There is no need to report them, although patches to fix them are welcome. If you discover a bug that is not listed here, nor in the compatibility table on the website, please see below. Indy 4 (Fate Of Atlantis): - Keyboard fighting does not work. ScummVM now defaults to using mouse fighting. Sam and Max: - Subgames are not fully functional. - Game may freeze if you look at the Dragon Heart, or trip an alarm, at Bumpusville - Some overlap may occur in graphics, expecially the intro - Music does not work in adlib mode, use midi Loom (256 Talkie): - CD music and voices are not always syncronised - Actor masks are not yet used - actors will always appear 'on top' of everything. - If you are having random crashes, this is a Windows bug. Try copying the data files from CD to your harddisk. Reporting Bugs: --------------- To report a bug, please create a SourceForge account and follow the bugs link from our homepage. Please make sure the bug is reproducible, and still exists in the latest daily build/current CVS version. Also check the compatibility listing for that game to ensure the issue is not already known. Please include the following information: - Game version (PLEASE test the latest CVS/Daily build) - Bug details, including instructions on reproducing - Language of game (English, German, etc) - Version of game (Talkie, Floppy...) - Platform and Compiler (Win32, Linux, etc) - Attach a save game if possible - If this bug only occured recently, please note the last version without the bug, and the first version including the bug. That way we can fix it quicker by looking at the changes made. Compiling: ---------- You need SDL-1.2.2 (older versions may work, but are unsupported), and a supported compiler. Several compilers, including GCC, mingw and Microsoft Visual C++ are supported. If you wish to use MP3-compressed CD tracks or .SOU files, you will need to install the MAD library and define COMPRESSED_SOUND_FILE. Tools for compressing .SOU files to .SO3 files can be found in the 'tools' CVS module, or in the 'scummvm-tools' package. GCC: * Type make (or gmake if that's what GNU make is called on your system) and hopefully ScummVM will compile for you. Microsoft Visual C++: * Open the workspace, scummwm.dsw * If you want to compile the GDI version, remove sdl.cpp from the project and add windows.cpp. for the SDL version, remove windows.cpp from the project and add sdl.cpp. * Enter the path to the SDL include files in Tools|Options|Directories * Now it should compile successfully. Running: -------- Before you run the engine, you need to put the game's datafiles in a directory. The filenames must be in lowercase on *nix systems (monkey2.000 and monkey2.001). If you use a game with speech, the file monster.sou must reside in the same directory as scummvm. You can either place the scummvm executable in directory in your path, or place it one dir up from the games install dir. Here is a good example installation directory structure. /Games/LucasArts/ | +-- scummvm | +-- momkey/ | +-- samnmax/ In this installation, is either C: for Windows user, or /usr/ for *nix systems. To run Monkey Island from this install as a Windows user you would make a shortcut with this command: C:\Games\LucasArts\scummvm.exe -f -pC:\Games\LucasArts\monkey\ monkey Or, if you have, for example, Full Throttle on CD, and you CD drive is D:, and you wish to disable subtitles and run in fullscreen: C:\Games\LucasArts\scummvm.exe -f -n -pD:\resource\ ft The short game name you see at the end of the command line is very important. You can get the current list of games and game names at: http://scummvm.sourceforge.net/compatibility.php For the adventurous, who like to live on the edge... you can download daily builds of Win32, Redhat, Debian and other packages here: Daily builds - http://scummvm.sourceforge.net/daily/ Command Line Options: --------------------- scummvm [OPTIONS] [GAME] [GAME] - Short name of game to load. E.g. monkey for Monkey Island. -p - Path to where the game is installed. Default is Cwd. -b - Start in room . -c - Drive to play cd audio from. E.g., 0 is first drive. -s - Set the sfx volume, 0-255. Default is '100' -m - Set the music volume, 0-100. Default is '60' -t - Set music tempo. Default is '2031616' -e - Select sound engine. See below. -g - Select graphics scaler. See below. -f - Full-screen mode. -n - Disable subtitles. Use with games that have voice. -r - Enable Roland conversion. Try if music sounds incorrect. In game Hot Keys: ----------------- Ctrl 0-9 and Shift 0-9 - load and save states. Ctrl-Alt 0-4 - cycles between filter modes Ctrl-z - quits Ctrl-f - runs in fast mode. Ctrl-d - starts the debugger. Ctrl-s - shows memory consumption. F5 - displays a save/load box. Space - pauses. Alt-Enter - toggles full screen (on *nix only) Graphics filters: ----------------- ScummVM offers several anti-aliasing filters to attempt to improve visual quality. These are the same filters used in many other emulators, such as MAME. They are: -gnormal - No filtering, original 320x200 resolution. Fastest. -g2x - No filtering, double screen/window size to 640x480 (default) -g3x - No filtering, triple screen/window size to 800x600 -g2xsai - 2xsai filtering, double screen/window size to 640x480 -gsuper2xsai - Enhanced 2xsai filtering. 640x480 screen/window size -gsupereagle - Less blurry than 2xsai, but slower. Also 640x480 Note that filters are very slow when ScummVM is compiled in a debug configuration without optimisations. And there is always a speed impact when using any form of anti-aliasing/linear filtering. Music and Sound: ---------------- By default, on most operating systems, ScummVM will automatically use ADLIB emulation. However, some games do not include Adlib music - such as Sam and Max. Note: MIDI may not be available on all operating systems or may need manual configuration. If you ARE using MIDI, you have several different choices of output, depending on your operating system and configuration. -eadlib - Uses internal Adlib Emulation (default) -ewindows - Windows MIDI. Uses built-in sequencer. Only on Windows -etimidity - Uses Timidity for music. Requires Timidity. -eseq - Uses /dev/sequencer for MIDI. *nix only. -eqt - Quicktime sound, for Macintosh users. -eamidi - Uses the MorphOS MIDI system. MorphOS only. -enull - Null output. Don't play any music. Playing sound with Adlib emulation: ----------------------------------- By default an Adlib card will be emulated and ScummVM will output the music as sampled waves. This offers far superior performance to Timidity, however does not work with some games such as Sam and Max. Playing sound with MIDI: ------------------------ Use the appropriate -e command line option from the list above to select your prefered MIDI device. For example, if you wish to use Windows MIDI over the default Adlib Emulation, use the -ewindows option. Playing sound with Sequencer: ----------------------------- If your soundcard driver supports a sequencer, you may set the environment variable "SCUMMVM_MIDI" to your sequencer device - eg, /dev/sequencer Then start ScummVM with the parameter '-eseq'. This should work on several cards, and may offer better performance and quality than Adlib emulation. Playing music with Timidity: ---------------------------- Start Timidity with the following command line : $ timidity -irv 7777 Then start ScummVM with the parameter '-etimidity'. However, Timidity is not designed to cope with the rapid changes most iMUSE equipped games use - so its use over Adlib emulation or sequencer support is not recommended. Using MP3 files for CD audio: ----------------------------- Use LAME or some other mp3 encoder to rip the cd audio tracks to files. Name the files track1.mp3 track2.mp3 etc. ScummVM must be compiled with MAD support to use this option. You'll need to rip the file from the CD as a WAV file, then encode the MP3 files with the following LAME command line: lame -h -t -q 0 --vbr-new -V 9 -b 24 -B 32 --resample 22.05 track1.wav track1.mp3 Compressing MONSTER.SOU with MP3:. --------------------------------- You need LAME, and our extract util from the tools dir to perform this task, and ScummVM must be compiled with MAD support. Make a backup file of your MONSTER.SOU before attempting this. Copy your MONSTER.SOU file to a temporary folder. Then run: extract monster.sou In about 30 minutes or so, you will have a much smaller monster.so3 file, copy this file to your game dir. You can safely remove the monter.sou file. Savegames: ---------- Savegames are by default put in the current directory. You can use the environment variable SCUMMVM_SAVEPATH to specify where to put save games. Don't forget the trailing directory separator. Also be aware that saved games can, and probably WILL, break between ScummVM releases. Bash Example: export SCUMMVM_SAVEPATH=/tmp/scummvm_savegames/ Windows example: set SCUMMVM_SAVEPATH=C:\saved_games\ Coding style: ------------ For ScummVM coding, we use hugging braces, and two-space tab indents. We occasionally run the following 'indent' parameters to ensure everything is kept standard: -br -bap -nbc -lp -ce -cdw -brs -nbad -nbc -npsl -nip -ts2 -ncs -nbs -npcs -nbap -Tbyte -Tvoid -Tuint32 -Tuint8 -Tuint16 -Tint -Tint8 -Tint16 -Tint32 -TArrayHeader -TMemBlkHeader -TVerbSlot -TObjectData -TImageHeader -TRoomHeader -TCodeHeader -TResHdr -TBompHeader -TMidiChannelAdl -TGui -TScumm -TSoundEngine -TPart -TPlayer ------------------------------------------------------------------------ Good Luck and Happy Adventuring!
