InGameFlags

[SomeJakeGuy]

One of the things I previously found is the in-game flag system. There is up to 255 flags, where 0-84 are for savable flags in the memcard (they are toggled on and stay on until either some function, in-game event, or observer turns them off), 85-169 is for flags that are within Mansion rooms (they can be turned on by any means, but reset back to off when Luigi leaves a room), and 170-255 are map flags which stay on once turned on (unless function/event/observer turns it off) until Luigi changes maps.

I am going to call this InGameFlagUtil.cpp
Globally, flags are stored at 803d3399 through 803d33b8

Function split will be from 80065fa4 through 80066d70 (80066d74 starts an unrelated function).
Some of this is used in JmpMessage and other ToolData, such as characterinfo, eventinfo, observerinfo, generatorinfo, and keyinfo (plus their blackout variants if applicable)

Heres some docs about flags that may be useful:
https://www.lmhack.net/Flags

It does contain offset info about these flags, however thats probably not as useful for decomp as knowing what each id corresponds to

Yeah I have that site already bookmarked for other reasons lol. Fortunately enough as one of the people that made the LM randomizer I know roughly what each flag does.

The only thing that site is really missing is PRM file information and notations but I do have a repo where I analyzed the file bytes to learn it's structure.

funnily enough I've decompiled some of the param code just today lol

a decent chunk of it is similar to sms's (like tooldata) but the Luigi's Mansion implementation seems to make it so that the const char* load for TParams also requires you to provide a JKRFileFinder pointer while in SMS they moved this to a static member of TParams

[SomeJakeGuy]

Yeah I noticed something similar when I tried to decompile it in my private repo lol. SMS also only seems to really use it in a couple instances whereas like every enemy in Luigi's Mansion literally uses it for like anything that moves lol. Do note that while there are properties defined in a lot of these files, they aren't always moved, i.e portrait health is hardcoded to be capped at 100 so we had to get some custom code to be able to change that. Odd choices they made

https://github.com/BootsinSoots/Archipelago/blob/Luigi%27s-Mansion-AP/worlds%2Fluigismansion%2Fiso_helper%2FLM_Randomize_ISO.py

Wanted to link this out here as well. This is where all of the randomizer code I have lived within Archipelago/AP (if you aren't familiar with it, basically its a program that randomize multiple games together into one big item pool/multi-world. If you get a star in SMS it could be Luigi's heart key in LM. Opening a furniture piece could be a badge in a Pokemon game, etc.)

The main file is the LM_Randomie_ISO.py where I use a library called gclib to basically extract the users iso, update various files including game_usa, jmp tables, and the dol to randomize various elements about the game, then use gclib to recompact it back into iso format. Since I have to change sooooo much about most of these jmp tables that's were I am the most familiar, but I also plan to assist a lot with the event system it uses as well. Not sure if any of this will help but feel free to poke around and ask questions too
