b..can you please thell me which line stands for the part of the french coast just to the east of Dieppe, where there are no sand beaches? That must be one of the lowlands lines..that's the only info I need to solve it, but I just can't figure it out.. thanks in advnace!

That's not how it works. There's not a line for each area. Bascially map_t has pixels of different RGB values and each value corresponds to one of the lines in the load.ini. You'll just have to live with it
