I know there should be any activity but nothing happens. I'm also surprised that I can use gainroot without installing anything before. Maybe I have activated the RD mode. I will reflash my device and see if it helps. Thanks so far.

Nothing happens when entering these commands (after sudo gainroot). Do you have a Nokia N800 or N810 and are able to test the installation of ScummVM 1.8?

OS2008 Version: 5.2008.43-7

Yes, I downloaded it from the scummvm.org website and tried to install it with the application manager...no success. I also tried to install the "libmpeg2-4_0.4.1-3maemo1_armel.deb" from your link...resulting in a message "package not compatible".

Maemo-extras repo is defined but cant't find libmpeg2-4 there. Installing ScummVM 1.5.0 from repo works. I have not tested 1.6.0 or 1.7.0.

I would like to install ScummVM 1.8 on my Nokia N810. However, during installation an error occurs, that libmpeg2-4 is not installed. Where can I find the necessary files?

Stephan
