To be even more complex... when I said setting map pixel size at 200... NO... I don't remember wich map pixel size I've set I tried many with only one ambition : making the greatest size including all islands and loadable in game... I think it was 115 but I'm not sure and I haven't keep any notes about... and I deleted basic files :x

This should not be a problem, because map_c and map_t are the only files you need to make map_f.

Map_c tells where is land and where is sea, if map_c says that a pixel is sea, then whatever map_t says, it will show like sea. But it's better having one of the sea or coast textures in map_t, to avoid strange things if there is land near the border of map.

For my method you only need map_c and map_t, so no need of other files you deleted
