Here are a few more details from the author:

Progress is going quiet well with Ports of Call DS. So good even that i descided to put a little teaser online of the progress.

The game mechanics are in place and the basic elements such as trade and travel can be done. What is still left open is banking and map events. When i am finished with those parts i know how much memory is still available for sound effects and music.
