Playing Gemini Rue under Linux with the native AGS engine

Gemini Rue
I’ve just finished playing Beneath a Steel Sky and started looking for another point-and-click sci-fi RPG and found Gemini Rue. It turned out that it uses the engine from Adventure Game Studio, which has a native port for Linux. Running the game using the native engine came out pretty straightforward. Here are the steps I had to follow.

Compiling the AGS engine

Simply following the readme from the AGS GitHub, first we install the dependencies:

sudo apt-get install git debhelper build-essential pkg-config libaldmb1-dev libfreetype6-dev libtheora-dev libvorbis-dev libogg-dev

Then we clone the repo and build the engine:

git clone git://github.com/adventuregamestudio/ags.git
cd ags
make --directory=Engine

Fixing the sound

The first time I tried to run the game, I got the following error, and correspondingly, there wasn’t any sound in the game.

Checking sound inits.
AGS: Initialize sound drivers
ALSA lib rawmidi_hw.c:233:(snd_rawmidi_hw_open) open /dev/snd/midiC0D0 failed: No such file or directory

I found the solution in a forum post: loading the midi kernel module and making a symlink to the device node.

sudo modprobe snd_virmidi
cd /dev/snd
sudo ln -s midiC1D1 midiC0D0

Running the game

If you had the Windows setup binary like me, you have to extract the files from the setup exe. I used innoextract for that:

sudo apt-get install innoextract
innoextract setup_gemini_rue_1.0.0.4.exe

The “Gemini Rue.exe” can be found in the newly created “app” directory. Now, from the Engine directory of AGS we just call

./ags --windowed /path-to-Gemini/app/Gemini\ Rue.exe

Enjoy the game!
