thanks JLF65 for the great infos... :-)
but i´ve got some troubles...there are 17 different tilesets but only 4 will be used at the same time..
how did we know which tileset is currently used..??
and:
imagine you would create a BMP with the sizes 32768 * 32768 pixel..with a depth of 8 bit (256 colors)
you will get exacly a file with a size of 1 GByte without the fileheader...phew...really big...
does your brother already started to create the map...maybe i can help him... :roll:
