I couldn't get any of the already available OpenTTD ports to work on my N810, so I decided I would start yet another one, this time from a pristine OpenTTD-0.7.0.

And either 0.7.0 has some fixes for arm or the CFLAGS I gave it did wonders ( -Os -march=armv6j -mtune=arm1136jf-s -mfpu=vfp -mfloat-abi=softfp), because this is the first openttd binary I've found that works for more than 30 seconds without crashing on my N810!

Also, many of the features of previous ports seem to be now in the upstream package (like tap-to-drag): thank you all! This port is way simpler for this reason.

Port features:

• The usual SDL hildonization: appears on task navigator and application menu; does not have mouse cursor.
• Icons everywhere (including application manager)
• Kinetic scrolling
• Fullscreen and zoom in/out button support

This version stores saved games on My Documents/Games/OpenTTD , and searches its data files in /usr/share/games/openttd (the data package symlinks that folder to memory card if appropiate).

Download:
Now available in maemo.org extras! Use the Application Manager to install it.

You no longer need to have the commercial data files (trg??.grf and sample.cat), but if you want them, they are available in the original Windows game disc. Read OpenTTD wiki for details.

Or you can also use the OpenGFX package available in extras-devel.

Standard disclaimer: backup your files, savegames, your money, everything you can before using this. Also be sure you can download the previous version (just in case something goes wrong).

Source is available in extras too.
