I tried everything to get JA2 1.13 running on N900, including mumbo jumbo rituals, however I was unsuccessful in my quest. Last hope, I will give anyone who gets it running and playable on maemo 50EUR (70USD), the bloody game is worth it (every cent). This is the only game I currently miss on my N900 and I guess it is possible, as the engine itself is working and 1.13 mod consist just from many subtle changes.
