SymbianOS FAQ

Any chance of a port to Epoc32/S50?

I own a Psion 5MX. Is a port to this old platform considered? Or did the architecture change too much between Epoc32 and S60? That platform has just too little memory and is to slow. For comparison: the S60 running at 103 MHZ is almost too slow, and 8-11 mb of free memory is not enough either. And also the MX is in greyscale.

How to install on devices with <4MB diskspace left (N-Gage and others)?

To get it to install please try the following:

• download the correct Symbian installer binary for your phone
• extract the files with UnMakeSIS.exe to a temp folder
• copy the entire System folder and Document folder to your MemoryCard or internal disk
• create the dir C:\documents\EScummVM\ (this is where the config file is stored)
• run it & enjoy!

Crashes / no sound support on Symbian S60 devices?

When starting any of the games, i'm getting an error message:

App. closed
SDL_b
E32USER-CBase 66

After selecting OK, the game starts (no sound, though).

Symbian S60 V1 devices are very timing sensitive. This means that you should set the music driver to NO music... and this will retain sound fx, but will not play any music. I have managed to get sound from my n-gage, but sometimes you need to reboot your phone between games.

The the 6600 is extra extra sensitive about the sound timing, and can very easily crash if something is wrong. This is something I have been trying to work around, but still is not 100% perfect.

I will try using a sample rate of 8khz and which seems to be working better than the 16khz I am trying to use, even though the sound quality is much worse. There will be a special 8khz build available soon.

I feel adventurous, can I build ScummVM for SymbianOS myself?

Sure, this is possible, but not as easy as doing this on Linux or Windows. Building EScummVM yourself using the UIQ 2.1/Nokia S60 SDK/Nokia S80 SDK/Nokia S90 SDK framework is not an easy task! Lets just say the frameworks needs quite some time to set up and take a while to get used to. If you choose to continue you will need some or all of the items on this page. Please check the README included in the source package for the information you need to get started on this perilous endeavor.

What can I do when my game X keeps crashing with an Out of Memory error?

Because of a new automatic build script we can now make a great number of specific builds for each phone type. We have decided to make versions of ScummVM with only one engine compiled in, so there is more memory left to run the game(s). These special versions can be found on the cvsbuilds page. If you keep having problems you can give one of these versions a try. Be advised that you can only play the game(s) that go with that specific engine! You can install these new versions over the old ScummVM versions, just choose 'Replace' during the installation process. Your configuration file will not be overwritten.

How can I switch between Joystick/Key/Cursor and Shrinked/Zoomed/Upscaled modes?

• 0 is the Control Key, it is pressed simultaneously with other keys to activate the mode changes in SDL for SXX phones
• 0+1 = change Input Mode: Joystick | Keyboard | Cursor
• 0+2 = change Video Mode: ShrinkedLandscape | ShrinkedPortrait | ZoomedPortrait (S60) and Upscaled | Normal (S80/S90)
• 0+3 = change Orientation Mode for ShrinkedPortrait: 90° Left | 90° Right

What are these Joystick, Keyboard and Cursor modes anyway?

Joystick mode sends SDL joystick events to ScummVM which acts as a mouse control in ScummVM. Cursor mode sends keyboard arrows instead, so for example it can be used to navigate through directorylist (one hand use perhaps!?) or save games etc. Keyboard mode is only available for S60 and enables multi-tap to enter text characters in save dialogs. These modes are implemented at the underlying SDL level, so this determines the types of events that ScummVM receives from SDL.

What are these Shrinked and Zoomed modes anyway?

Shrink displays the game on your screen but in a shrinked way, either in Portrait or Landscape mode, so not all the pixels can be seen. Zoom mode uses the maximum resolution of your phone displaying a smaller part of the game zoomed at 1:1 pixels. For scrolling in Zoom mode: 0+Cursor keys to scroll around, 0+Ok button to center view.

Why does ScummVM on S60 not react when I press two buttons at the same time?

Try leaving the application by pressing the App button. Then press and hold the App button and switch back to ScummVM and see if it helps. Multikeypress is a known problem on S60 devices. So sometimes it is reset to no multiple keypresses and then the system key won't work.
