I added LttP-style rails to significantly-edited GB mountains These feature a large number of useful transitional tiles to allow you to create as complex or as simple of terrain as you want. Furthermore, I included transitional chasm tiles and a number of chasm boulders to help you create areas like LttP's light world death mountain.

I attempted to translate it to a few popular tilesets: DoR, EZGBZ, Firebird, Vintage Dreams, and PTUS. They translated a little better to some than others. Notably, I used the darkest green in lieu of the brown for PTUS since the palette I found only had 3 browns to work with. For EZGBZ, Firebird, and Vintage Dreams, the tiles are slightly different featuring some color reduction and alterations to the chasm boulders in an attempt to preserve fidelity of the chasm transitions.

I also packed the tiles into columns in a way I think I would find useful.

EDIT - 1 April 2025 - Included a version for Newfirst.

Plith - This work began with edits to the variant of GB mountains found in Plith's Descendant tiles which is also where I got the palette
Nintendo - for the base tiles obviously and the chasm twinkles which were just ripped straight from LttP
