Everything was already supposed to be up to date, I downloaded and copied the files from the link just in case, but it still doesn't work.My first thought is sigpatches. Try installing the latest from https://sigmapatches.coomer.party/
So my only guesses are that there is a difference in the Cotton Boomerang NSPs, and somehow that's significant? Or your prod keys is wrong/bad?
I tried to use Cotton 2 as base too but it doesn't work either. It might be of interest that the Cotton Guardian Force game never ever worked on my Switch, no matter where I get the file from, nor if it is NSP or XCI. Another game that I was never able to launch no matter the source is Chocobo Every Buddy btw. It might be related ?
As for the prod keys, well I got it with Lockpick RCM and followed a tutorial, nothing seemed to go wrong, but I might as well just try again just in case. EDIT : OMG I reripped the prod keys and it works ! Can't believe it lol. The game seems to have no sound though, maybe I should try another copy of the game.
