From the Luma wiki:
Enable game patching [in the Luma config]:
- LayeredFS: This allows you to replace files inside the romfs of a game/application.
- To use this feature, create /luma/titles/TID/romfs and place the your modified files from the game's romfs into the romfs folder.
- Note: DLC patching and HANS-style romfs binary files (instead of a folder) are not supported at this time.
Is that what I'm suppose to be looking at? I'm all doing is changing files in the romfs so I'm assuming its this one.
So I but my edited files in this
/luma/titles/0004000000072A00/romfs
Ill have to give this a try later, hoping it works since rebuilding the rom is so tedious.
