I'm in the works of a mod for BFNS+, something like BFNS Full House Edition : it takes any open-source project on the final version of an edition of BFNS. It's certainly going to combine the pre-release, anniversary Plus and normal Plus together. I will likely not keep OCs though. Likely still possible to re-enable them, as a player of my re-mod, to spawn just by modifying Assembly CSharp in dnSpy, if the player prefers. OCs should still be left on the script in my release. If Remastered goes open source, I'll use that too, but if you prefer to not open-source that project, then I'll skip integrating remastered in my mod.
Also, same way as there's an open-source of the original camping demo, I plan to also release the Field Trip farm demo as open-source off the BFNS+ framework.
