So for Newer Super Mario Bros 2 (https://gbatemp.net/threads/wip-newer-super-mario-bros-2-a-nsmb2-level-hack.402816/) I want to create custom tilesets. I already have the files for it (I just edited a tileset I ripped with texturipper) and I want to know if I can repackage that into a .sarc file for use in game. Is there any way to do this?
