i wonder that is only one point i must change right or there are other point i must change?

Well , beside the "part number : 006-D2785-00" , I change the name to be "Narisa" and Map name to be "Thai_Narisa" , just like what Aekhong told us to do in the first page .

*** DO NOT use the delete button on the un-wanted character , go to the left panel and put "00 which is Blank" instead .
Finally , you will see that after doing the checksum , file size will be exactly the same as the old fw_all.bin.
