A transition between mountain and grass... I think I know what you mean for that one. There is a simple way, I didn't add it due to running out of room in the main tileset. It kinda involved using the tiles for the Puddle edges (yu know the ones), and instead of water, using the mountain tiles under, making it look like a path, in a way.
As for top of the mountain... That one I don't understand. Feel free to add to the ROM Base if you want - after all it is a base! Thanks for the feedback!
Ahhh finally, i've been trying to figure out whose it waas :D
Sorry i havent credited you, but i couldnt figure out for the life of me who it was, and it was the best rombase i saw :D
Infact, i'd like to ask you if i could use it for my hack? I love the tiles!
As for improving it, the only thing i can think of is that there isnt a proper tile for transition between mountain and grass.
Also, a tile for the 'top' of the mountain, with the ledge at the top of the tile.. Its hard to explain but i feel the transition is too strong..
