This is the variant of Nose Goes Definitive which uses the Programmer Art style. For netherite and copper helmets, textures are used from the Programmer Art Continuation Project with permission. The Wild trim is unchanged.
This mod is compatible with every version, all the way back to 1.6.1 when resource packs were added. In theory, there is no reason it should break with updates, excluding the addition of more armor types or trims.
Additionally, a "historical" version is available for the pre-1.6.1 texture pack format. While I've confirmed this works in the first version with this format, a1.2.2a, I have not tested thoroughly in between, so please inform me if there are any issues or discrepancies on a particular version, and I will gladly fix it.
