some bugs if you want to know them un til now:
if you go to the first route the game will freeze somewhere it seem everytime the same place
if you change in the header in advancemap tileset1 with tileset 2 or what ever tileset the trees and mountains youve inserted with diferent colors will disapear too coz since tileset1 only usese pallet one until pallet 6 the other pallets are from tilset1 and above
and rob it has to be at least 3 colours i think or it wont work:(]
i for example used the dark symbol from tcg
make it any symbol you like not tcg but some symbol for example that when others see it now that its darkblack:)
oh and you made an major mistake in your ips
the error is when you go to the first town in your game chnage for example tileset1 with tileset2 in the header and see what happen
