I think it’s possible to get this texture mod on the 3ds, but don’t ask me how! What I found online was that you can use mods on the 3ds by adding the “romfs” folder to luma/title/[Title ID] of MH4u/. It also said that you might also need two files called code.bin/code.ips and exheader.bin. I tried to put the romfs folder from “mod quests” (not sure what that does exactly) there because there was a romfs folder in it and there was none in “mod textures” so I had no idea what to do with it (still have no idea). It didn’t work or had no visible effect on me. I searched online and saw that there is a homebrew app for the 3ds called Modmoon that can be used to mod 3ds games on the 3ds… but I have no idea how to use it.

So if someone manages to make this texture mod available for 3ds, which i think is possible since there are mods for fire emblem and Pokemon games, it would be great if the person could make a tutorial.
