ScummVM Windows CE FAQ Last updated: $Date$ Release version: 0.10.0 ------------------------------------------------------------------------ New in this version ------------------- 0.10.0: Major improvements have taken place in this version, mostly for behind- the-scenes stuff. First, we have migrated to GCC for building the Windows CE port. This helped take care of some obscure compiler bugs which were in there for quite a long time. It has also lead to efficient code generation due to GCC's advanced capabilities and consequently increased runtime speed. The second important change was the overhaul of the SDL library port. The benefits from this are twofold: The real-time code paths have been optimized, including contributed ARM assembly code for critical functions. Further, the screen display and mouse/keyboard input code has been partially rewritten to allow for increased compatibility across all devices. Due to the update of keyboard handling code, the keycodes have changed slightly. Running this version of ScummVM will overwrite your key bindings with the new defaults. See the section on how to play on Smartphones and Pocket PCs below for the new default keybindings. ------------------------------------------------------------------------ This document is intended to give common answers to specific ScummVM issues on Windows CE, in 3 sections * "General questions" : browse this section to get started and see general issues * "Game specific questions" : lists some common game specific issues * "Support and links" : how to get support if you're still puzzled ------------------------------------------------------------------------ General questions ------------------------------------------------------------------------ Which devices are supported ? ----------------------------- Official build -------------- The official build is based on the ARM architecture and should work with any Pocket PC 2000, Pocket PC 2002, Pocket PC 2003, Pocket PC 2003 SE, Smartphone 2002, Smartphone 2003 or Windows Mobile based device. Support for old ARM architectures (Handheld PCs, Palm Size PCs) and other CPUs (MIPS, SH3) is discontinued. Feel free to generate builds for these architectures and contact us to include them on ScummVM website. Games supported --------------- The Windows CE port of ScummVM supports all available game engines. ScummVM distinguishes devices based on two characteristics: Type and resolution. Supported types of devices are Smartphones (usually no stylus) and Pocket PCs (stylus). The supported resolutions are 176x220 (Smartphone), 240x240 (QVGA square), 240x320 (QVGA), 320x240 (QVGA landscape), 480x640 (VGA). Devices with resolutions larger than VGA should also be supported with automatic screen centering. * Low resolution Smartphones (176x220) Support is only provided for all 320x200 or 320x240 games. The font can get hard to read (you should prefer talkie games, or wear glasses :-P) Games with 640x480 resolution such as COMI or BSWORD cannot be scaled down to this resolution and still be playable. * QVGA square devices (240x240) Only 320x200 or 320x240 games are supported due to lack of downsampling scaler. * QVGA Pocket PCs or Smartphones (240x320 or 320x240) All games are playable in these devices. Landscape devices may not be able to rotate the screen around. * VGA (640x480) or higher Pocket PCs All non VGA games should work properly on these devices. They can be resized with different scalers. Moreover, VGA games will be displayed in true VGA mode. Partial / Discontinued support ------------------------------ Support for the following devices is not complete, not working properly or discontinued because the device is now obsolete. Feel free to contribute and improve the port for your favorite device, or use the last release built with the previous port architecture (0.5.1) which was less resource hungry and supported more exotic devices. * "Paletted" devices (non "true color") These devices will be supported through the GDI layer which will slow down the games a lot. You can try to disable the music/sound effects to get a better game experience. * "Mono" devices I don't even think anything will be displayed on these devices :) you can try and report your success ... * MIPS/SH3 devices with QVGA resolution (240x320), "true color" Some devices may be a bit too slow, especially if direct screen access (GAPI) is not supported on these devices. * ARM/MIPS/SH3 devices with VGA resolution (640x480) (Palm Size PC / Handheld PC platform) True VGA games will probably be too slow to run properly on these devices even if they can support them ... * ARM/MIPS/SH3 devices with desktop resolution (800x600) (Handheld PC platform) No, there will never be ANY scaler supporting 800x600 resolution, because 320x200 games CANNOT be resized to a 800x600 by a simple operation. And the device will probably be too slow to perform any kind of graphic transform anyway :) How do I install ScummVM for Windows CE ? ----------------------------------------- Simple! Unpack the release package on your desktop pc, then copy all its contents to a folder on your device. Typically, you should at least have scummvm.exe, modern.ini and modern.zip in the same directory. Finally, upload your beloved games and fire it up :-) Some devices (like Pocket PC 2000) require GAPI to be present. How do I install a game ? ------------------------- You'll at least need to copy all the data files from your game, in a sub-directory of your game directory. You'll need to put the data files in a directory named after ScummVM game name (see "Supported Games" section in ScummVM readme) for the games having "generic" data files (.LFL files). Recent games can be put in any directory. You can compress the multimedia files (sound/video) as described in the ScummVM readme. You can compress the audio tracks of Loom or Monkey Island 1 as described in the ScummVM readme. If you are running these games on a slow device with Ogg Vorbis compression, it's recommended to sample the files to 11 kHz (this sample rate is not supported by other versions of ScummVM). If you need more details, you can check SirDave's mini-manual online available at: http://forums.scummvm.org/viewtopic.php?t=936 and at: http://www.pocketmatrix.com/forums/viewtopic.php?t=8606 How do I run a game ? --------------------- If it's the first time you're running ScummVM for Windows CE, have installed or removed games, you need to rescan your game directory. * Select Add Game, tap the root directory of your games, and tap "Yes" to begin an automatic scan of the installed games. Usually all games are detected and you can start playing right away. If your game is not detected check its directory name and your data files. To play a game, tap on its name then tap the "Start" button or double tap its name. How do I play a game on a Pocket PC or Handheld PC device ? ----------------------------------------------------------- The stylus is your mouse cursor, and a tap is a left mouse button click. As the Pocket PC lacks some keys, a toolbar is displayed at the bottom of the screen to make the most common functions just a tap away * The disk icon opens ScummVM options menu to save your game, or change your current game settings (depends on the game) * The movie icon skips a non interactive sequence, the current dialog or behaves like the ESC key on a regular keyboard (depends on the game) * The sound icon turns all sound effects and music off and on * The key icon allow you to map a key action to a device button * The monkey icon switches between portrait, landscape and inverse landscape mode (depends on the display drivers) You can map additional actions on your device hardware buttons using the "Options" / "Key" menu in the ScummVM options menu. To associate an action to a key, tap the action, then the "Map" button and press the hardware key. The following actions are available : * Pause : pause the game * Save : open ScummVM option menu * Quit : quit ScummVM (without saving, be careful when using it) * Skip : skip a non interactive sequence, the current dialog or behaves like the ESC key on a regular keyboard * Hide : hide or display the toolbar * Keyboard : hide or display the virtual keyboard * Sound : turns all sound effects and music off and on * Right click : acts as a right mouse button click * Cursor : hide or display the mouse cursor * Free look : go in or out of free-look mode. In this mode, you can tap the screen to look for interesting locations without walking. * Zoom up : magnify the upper part of the screen for 640x480 games rendered on a QVGA device. * Zoom down : magnify the lower part of the screen for 640x480 games rendered on a QVGA device. * Multi Function : this key performs a different function depending on the game : Full Throttle -> win an action sequence (cheat) : Fate of Atlantis -> sucker punch (cheat) : Bargon -> F1 (start the game) : All AGI games -> bring up the predictive input dialog * Bind keys : map a key action to a device button * Up,Down,Left : Right, : emulate mouse/stylus behavior Left Click : The default key bindings for Pocket PCs are (note that not all keys are mapped): * Up, Down, Left, Right : (dpad) arrow keys * Left Click : softkey A If you start a game when a Right click mapping is necessary, ScummVM will ask you to map one of your hardware key to this action before playing. Just press the key you want to map if you see this message. Notes: - THE TOOLBAR CAN BE CYCLED BY DOUBLE TAPPING (SEE BELOW) - YOU MUST HIDE THE TOOLBAR TO SCROLL THROUGH THE INVENTORY IN ZAK - YOU MUST DISPLAY THE KEYBOARD TO FIGHT IN INDIANA JONES 3 - YOU MUST MAP THE RIGHT CLICK ACTION TO PLAY SEVERAL GAMES How do I hide the toolbar ? --------------------------- Note: THIS IS A VERY USEFUL AND SOMETIMES NECESSARY SHORTCUT Double tapping the stylus at the top of the screen will switch between a visible toolbar panel, a virtual keyboard, and hiding panel. If any part of the screen is obscured by the toolbar (like the load/save game dialogs) you can use the invisible panel mode to get to it. For 320x200 games on QVGA Pocket PCs, when the panel is hidden the game screen is resized to 320x240 (aspect ratio correction) for better gaming experience. How do I play a game on a Smartphone device ? --------------------------------------------- On non-stylus devices, the mouse cursor is emulated via a set of keys. The cursor will move faster if you keep the key down. You can tweak this behaviour in the configuration file described below. Here is the list of available actions for Smartphones: * Up,Down,Left : Right, : emulate mouse/stylus behavior Left Click : Right Click : * Save : open ScummVM option menu * Skip : skip a non interactive sequence, the current dialog or behaves like the ESC key on a regular keyboard * Zone : switch between the 3 different mouse zones * Multi Function : this key performs a different function depending on the game : Full Throttle -> win an action sequence (cheat) : Fate of Atlantis -> sucker punch (cheat) : Bargon -> F1 (start the game) : All AGI games -> bring up the predictive input dialog * Bind keys : map a key action to a device button * Keyboard : hide or display the virtual keyboard * Rotate : rotate the screen (also rotates dpad keys) * Quit : quit ScummVM (without saving, be careful when using it) The "Zone" key is a *very* valuable addition allowing you to jump quickly between three screen zones : the game zone, the verbs zone and the inventory zone. When you switch to a zone the cursor will be reset to its former location in this zone. The default key map for these actions is: * Up, Down, Left, Right : (dpad) arrow keys * Left Click : softkey A * Right Click : softkey B * Save : call/talk * Skip : back * Zone : 9 * Multi Function : 8 * Bind keys : end call * Keyboard : (dpad) enter * Rotate : 5 * Quit : 0 You can change the key mapping at any time by bringing up the key mapping menu (Bind keys action). How do I tweak the configuration of ScummVM ? --------------------------------------------- See the section regarding the configuration file (scummvm.ini) in ScummVM README file - the same keywords apply. Some parameters are specific to this port : Game specific sections (f.e. [monkey2]) - performance options * high_sample_rate bool Desktop quality (22 kHz) sound output if set. 11 kHz otherwise. The default is 11 kHz. If you have a fast device, you can set this to true to enjoy better sound effects and music. * FM_high_quality bool Desktop quality FM synthesis if set. Lower quality otherwise. The default is low quality. You can change this if you have a fast device. * sound_thread_priority int Set the priority of the sound thread (0, 1, 2). Depending on the release, this is set to 1 internally (above normal). If you get sound stuttering try setting this to a higher value. Set to 0 if your device is fast enough or if you prefer better audio/video synchronization. * Smush_force_redraw int Force a Smush frame redraw every X missed frames. Mainly used for Full Throttle action sequences. Setting it lower gives more priority to screen redraws. Setting it higher gives more priority to stylus/keyboard input. The default is 30. Game specific sections (f.e. [monkey2]) - game options * landscape int 0: Portrait, 1: Landscape, 2: Inverse Landscape You can also use this in the [scummvm] section in QVGA Pocket PCs to display the launcher in landscape, for example, at startup. [scummvm] section - keys definition You usually do not wish to modify these values directly, as they are set by the option dialog, and are only given here for reference. * action_mapping_version int Mapping version linked to ScummVM version. * action_mapping string Hex codes describing the key associated to each different action. * debuglevel int Debug Level 1 is used by the WinCE port for reporting diagnostic output in the scummvm_stdout.txt and scummvm.stderr.txt files in the current working directory. [scummvm] section - mouse emulation tuning You can tweak these parameters to customize how the cursor is handled. * repeatTrigger int Number of milliseconds a key must be held to consider being repeated. * repeatX int Number of key repeat events before changing horizontal cursor behaviour. * stepX1 int Horizontal cursor offset value when the key is not repeated. * stepX2 int Horizontal cursor offset value when the key is repeated less than repeatX. * stepX3 int Horizontal cursor offset value when the key is repeated more than repeatX. * repeatY int Number of key repeat events before changing vertical cursor behaviour. * stepY1 int Vertical cursor offset value when the key is not repeated. * stepY2 int Horizontal cursor offset value when the key is repeated less than repeatY. * stepY3 int Vertical cursor offset value when the key is repeated more than repeatY. ------------------------------------------------------------------------ Game specific questions ------------------------------------------------------------------------ --------------- -- All Games -- --------------- I need to press a special key ----------------------------- Bring up the virtual keyboard. On Smartphones take a look at the Keyboard action above. On Pocket PCs it's easier to double-tap at the top of the screen. The panel is obscuring the playfield area ----------------------------------------- Double tap at the top of the screen to hide it. As an aside, the aspect ratio correction scaler will kick in if the game/device combo is appropriate. How do I name my save games ? ----------------------------- Use the virtual keyboard (Keyboard action). ScummVM is stuck for some reason -------------------------------- Bind and use the quit action to quit. I cannot rotate the screen to landscape/inverse landscape --------------------------------------------------------- Depending on the video driver, ScummVM may opt to not provide such functionality. In general, when ScummVM starts in normal "portrait" orientation, the device driver reports better display characteristics and you should consider launching from portrait. I'm having problems. Is there diagnostic output available ? ----------------------------------------------------------- Insert a line in the [scummvm] section of scummvm.ini with the following: debuglevel=1 Run ScummVM. When it closes scummvm_stdout.txt and scummvm_stderr.txt files will be available at the program directory (see section above). ScummVM crashes and returns to desktop -------------------------------------- File a bug report including diagnostic output (see previous question). -------------------------- -- Beneath a Steel Sky -- -------------------------- Introduction movie is too slow or never ends ... ------------------------------------------------- Skip it :) How can I open the inventory in Beneath a Steel Sky ? --------------------------------------------------- Tap the top of the screen.

Consider changing to the DXA cutscene pack which is many times faster. --------------- -- Gobliiins -- --------------- How do I enter a code ? ----------------------- Use the virtual keyboard. ------------------- -- Bargon Attack -- ------------------- How do I start the game (F1 : Game, F2 : Demo) ---------------------------------------------- Use the Multi Function action. ---------------------- -- AGI engine games -- ---------------------- Do you expect me to play these games on keyboard less devices ? --------------------------------------------------------------- Sure we do :-) If you want to get some mileage on your stylus you can use the virtual keyboard. There is a very useful alternative though, the AGI engine's predictive input dialog. It requires a dictionary to be present. Just tap on the command line or use the Multi Function action to bring it up. On Smartphones, when the dialog is shown all key mapping is disabled temporarily (including mouse emulation). Input is performed either by pressing the phone's numeric keypad keys and dpad enter to close the dialog, or by navigating the buttons using the dpad arrows and pressing with dpad enter. Check the main Readme file for more information on this. ------------------------------------------------------------------------ Support ------------------------------------------------------------------------ Help, I've read everything and ... ----------------------------------- Luckily, as there is a huge variety of Windows CE devices, a specific forum is dedicated to this ScummVM port.
