What's resnametable.txt do?
resnametable.txt makes a duplicate of map(the duplicated map files need not to be renamed and packed in GRF)
Beside that how I can change the default of main town or save point? So after they finish their first quest from "Training Grounds, new_1-1" map, they will redirected to the new main town and automatically save point there.
trunk/conf/char_athena.conf
// Start point, Map name followed by coordinates (x,y)
start_point: new_1-1,53,111
change [new_1-1,53,111] to the map you wanted.
