If any of these maps crash the game, please let me know and I'll try to fix the problem. I don't play FFXI anymore so it's hard for me to throughly test this.
You can download the DATs from filefront.com, or savefile.com.
To install the files, make sure you are fully logged out of FFXI and PlayOnline, then simply unzip the zip file to your PlayOnline\SquareEnix\Final Fantasy XI directory.
DO NOT INSTALL WHILE LOGGED INTO FFXI or POL or the game may crash or behave strangely.
