So, I'm an avid Zelda completionist. The games are a wonderful outlet for my OCD, along with collect-a-thons in general. I've put together a doc of steps for Ocarina of Time and Majora's Mask, for triggering every permanent flag (all cutscenes, owl appearances, one-time dialogues, room clears, etc, on top of all the regular 100% stuff), but the one thing that still eludes me is how Navi's dialogue flags work with the save format.
Is each hint she gives tied to a certain combination of bit-flips in the inf_table (https://wiki.cloudmodding.com/oot/Save_Format)? Or is her dialogue programmed around other flags, since her hints only change when you progress through the story? It seems like the latter would make more sense. The ultimate question I'm hoping can be answered by someone more knowledgeable of the save format's inner workings than I is whether or not I need to sit and wait for every one of Navi's unique hints in order to fully call the save file "perma-flag complete".
I have the same question about Tatl too, actually, especially since her hint flags appear to be tied to specific bits (https://tcrf.net/Proto:The_Legend_of_Zelda:_Majora%27s_Mask/Debug_Version/Event_Editor). I figured I'd mention that since they seem to be based on the same save format.
This is a really bad place for this as almost nobody here will understand what you're talking about lmao.
You're better off joining the OOT and MM discord servers (you can find links on the games' LBs) and discussing it with them. Several members there are deep into hacking and disassembling the game and they might be able to help a lot more with whatever questions you have on this topic.
