... Right... This makes the job longer... You insert the tiles. In fact, it would probably be quicker if you also inserted the Mart and PC, as I've got no time for puzzles, and I think I've screwed it up...
Great! Did you make sure that the colours had the amount of Red, blue and Green shading as a multiple of 8? Advance map only recognises the multiples of 8.
i got a picture of agate then took its colours then i got the agate cave tile and coloured it in those colours... it looks so much better! i think that should be the pallette, the good news is, it doesnt look half bad on the trees either!
