What is your suggestion, and why should it be implemented?

while fnfc contains all the resources for a song, theres currently no way for PlayState be initialized from it except via the chart editor

itd be nice if we could initialize PlayState or create a Song from an fnfc file, and/or just put it into the songs or data/songs folder under the respective song id and have the game recognize it and add it to the registry, instead of having to extract its contents to the right places

Are you asking for scripts to be able to load songs from .fnfc files? If so, then this sounds similar to #2363.

yes
the wording is a bit imprecise because i meant generally and not just freeplay/story mode, but im assuminggg solving their issue entails "detect and add fnfc to song registry" which would solve this issue as well
