[Gamemaker] .nrr extensions, how they works?

[Licuatronix]

OK so i tried to extract the fmod extension from the official pt port, for make homebrew ports with working fmod, but doesn't matter how many times i try, it allways crashs my game on start up, as anyone here tried to mess around with .nrr extensions before?

also yes i uncluded every fmod related file but it stills crashs

Dunno if we are talking about the same nrr, but NRR in context of Switch games consists of various informations necessary to load NRO executable. If NRR has 4 kB iirc, it's completely unrelated to what you are working on.

Oh i think i got it, nrr files are like a "license" that the game need to read before allow the execution of the nro file, right?

This mean that the extension is actually the nro file and not the nrr

It's a license and digital signature. In normal circumstances any modified NRO will fail to load, with atmosphere's ease_nro_restriction digital sign is not checked, but hashes still must match. That's why IPS NRO patches are a way to patch such file.

I tried using the nro as the extension file in gamemaker, but sadly it still doesn't work

Question about that, is it posible to use any nrr on any game right? Like what i trying to do, get a pt nrr and use it in other games

sadly i made no progress, but i starting to think that the extension is hardcoded
