Guys to find the MapID memory address you just need to do few simple steps.
Get cheat engine, T-search, ArtMoney or even Crysearch ... what ever.
1.) Go to Guanjin (Dragon) Clan main town.
2.) First scan, search the value 1 (4 bytes)
3.) Teleport to next map
4.) Secound scan, search for a 2
5.) Teleport back to town and search again for the 1 ...repeat that untill you find the right address.
6.) Change it to what ever you want or just freeze.
You done, have fun
