Hey everyone. Jupiter lighthouse is known as the most unbroken dungeon in TLA. Everything we've thought of has failed. I took another run at the Lighthouse today and made a curious observation concerning the retreat glitch.

Normally the retreat glitch works like this. After retreat has failed the game thinks you are in the room that you would have been sent to if retreat was successful (the 'retreat room'). Example - entering Airs rock through the second entrance makes the retreat point Area 55 Door 10, if you enter another Area of the dungeon (say Area 58) and use the retreat glitch then the Area is reset to 55, while you're still physically in Area 58. In this glitched state walking through doors loads the corresponding door in the retreat room. So if you're in Area 58 and walk through Door 3, instead of being sent where this door sends you instead you will be sent to where Area 55 Door 3 will send you.

Hopefully that's not too confusing.

In Jupiter Lighthouse this doesn't appear to happen. Regardless of which door you access, you always get sent back to Area 251 Door 0. This is the same location you'd be if you'd entered the dungeon from the overworld. I'm not sure if it is Door 0, but it certainly seems like it is.

I'm just wondering if there's anything special code wise surrounding this lighthouse that might explain this. I know that encountering Alex resets the last visited Sanctum to Contigo, but beyond that I don't know of anything.

It is most likely because the Retreat room uses a different map code file than the rest of the Lighthouse, so the map number doesn't get found.... and if none are found, it doesn't know what to change the map/door number to, so it leaves it as is?

http://forum.goldensunhacking.net/index.php?topic=1014.0 = This topic describes how Exit data is formatted, to point out that a map number is looked up. (Compared with what is stored at the value that gets changed when Retreat fails.) .... However, when I say "different map code files" then that means this gets changed as well... (02008000-0200FFFF = Map code file section.) (When Retreat fails, it doesn't revert back to the Retreat Map's Map Code, which would have been cool, but oh well. And even if it did in this case, then there wouldn't be much abuse you could do, could you? With only two doors that's nearly 10 seconds apart....)

Did you know? In English, you are suppose to capitalize the languages. (e.g. English is a proper noun.) Subjects like math, science, history can be left lower-cased unless they are a title. (Kind of like how you can say either "my mom" or "Mom" in "I went with (X) to the store.", except that I don't think languages are ever lower-cased in English.) In Spanish, both subjects and languages are left lower-cased. (I put this here because I've noticed people make this mistake quite often. And am curious if they know about this, and whether they use their way because they believe this grammar usage should have never been a thing?

Remember kids! In getting a job, it's not about what you know, it's about WHO you know! So start making friends with the people that work where you want to work. :) (Friend of a friend and volunteering count too, so keep that in mind.)[/si

The retreat glitch still works, just the every door sends you to the entrance of the dungeon (where you would have been sent if retreat was successful).

If I'm reading the editor correctly, I see the following exits; door 1 -> world map, door 2-> door 2 of 0xFE, door 3->door 3 of 0xFE, door 4 -> door 4 of 0xFC

This doesn't indicate that there's anything funny going on. Although I'm comparing it to another room which has a "madra warp" (felix gets sent to a default position on the world map) to see what is different. Along these lines, it's probably worth clarify exactly what is going when these madra warps happen.

One example is the 0xB door in room 0xCF (Tundaria Tower Interior). Door 0xB in map 0xCF gets sent to door 2 room 0xCF. If you retreat warp through the door you get sent to madra. Looking up Room 0xB relative to map 0xCE (which is where retreat would send you) would make the game read the blank code 0xFFFFFFFF

Does this mean that the game trying to send you to door 0xFF in area 0xFFF and this sends Felix to the default position on the world map? Or does the game try to look up Door 0xB in Map 0xCE, find nothing, then default you to the default position?

I noticed that the Jupiter Lighthouse stuff is missing any of the 0xFFFFFFFF separators, hence these questions.

EDIT: the first room of Jupiter lighthouse for convenience https://gyazo.com/bc4cb999812c43654b92e1cd6273409f

While I believe Jupiter is b/c of separate map code files... / Map's exit list not found ....
Tundaria is a different case... (It is the same file in both places)... In that case, map's exit list is found.... however, the exit is not (Exit 0xB is higher than how many the retreat room had...) So that one choose the map of the first entry. (Interesting/ assuming I read things right... was rather quick...) (Seems like the list detects entrance 0 as the end of a list of map exits.)

Exit data stops at 0x000001FF. (If you seen Atrius's topic, you'd know you can have multiple tables of these ending in that, but also multiple exit lists in one... erm... heheh.... )

080C9694 = Relevant function that scans the exit data... I probably should write up some psuedo-code, huh....?

Ah yup I get it now. Curious that some dungeons have map code files split and others not.

My guess is that its probably for compression/spacing. Not 100% sure...

If you have all map's map code files separated.... it might be too bulky in the ROM.
If you hae all maps using the same map code file.. well, we're limited to only 0x8000 bytes in RAM for it, so then it wouldn't fit.

Fox: Okay, so that Summon Night games adds the fram number to the seed, before generating another seed via mul/add....  (GS1-GS3 never adds the fram number.) ... So um, that makes sense! ;  Summon Night:  ((seed + frame) * 0x343FD + 0x269E3C) >> 0x10 ; Which is also on the list here: https://en.wikipedia.org/wiki/Linear_congruential_generator
December 12, 2017, 11:10:45 PM
Fox: Yes, and there could be contests. Maybe ones where 1st/2nd/3rd place get a cash reward, but eh. Dunno.... Kind of thinking about making a topic about how people got their job, and what was their experience. (e.g. Did they use references of people already working in the job, and various other things.)

Majora: Import old forum posts for reference, perhaps take posts containing important info like documentation away from the old stickied forum post model and make them into their own pages on a site with an in-built search bar. Might help with SEO, too. If nothing else, perhaps whipping them into PDFs and hosting them via Scribd? The possibilities are boundless when it comes to restructuring a site
December 09, 2017, 04:20:02 AM
Majora: Just a nice idea to have even if it doesn't come to fruition. Updating, modernizing, always a good idea. Could probably do something pretty nifty using a good Wordpress theme
December 09, 2017, 04:15:45 AM
Majora: Would be kind of neat to do something like that for GSHC. Could change it up a bit to show all tweets/instagram posts/facebook posts/golden sun subreddit posts all in one sidebar. It would be cool in that it gives the site it's on (and the topic in general) appear more lively and active, which is a plus
December 09, 2017, 04:14:19 AM
Majora: That does sound interesting. One cool thing I've seen some sites use is a sort of unique take on a sidebar option that acts like a social media integration (like, "See GSHC's latest Tweets"). It displays activity from a variety of related sites, such as Reddit, Twitter, Instagram, etc.

Fox: And the way it'd work via code is not that all users would instantly get nicknames the minute you register... but rather, the moment you view a name if it doesn't have a nickname, it gets one. (My Thoughts.)
December 09, 2017, 12:53:55 AM
Fox: (I was thinking that it would be "Name (Nickname)" ... The nickname is what you first known the user as, and you can change that yourself... and the Name is what the user wants to be called... Something like that.
December 09, 2017, 12:47:56 AM
Fox: So like... for starters, one idea I had was to make it so anyone can name anyone... much like how it works on Skype, and you (the namer) would be the only one to see it, and such...
December 09, 2017, 12:45:02 AM
Fox: Would need to be carefully thought out and tested, though.
December 09, 2017, 12:43:02 AM
Fox: I'm thinking I could make it so that name changes can happen whenever... (Without any limit)... Since I believe there's a way to do it with minimum confusion. (I think.) Hmm....
December 09, 2017, 12:31:36 AM
Fox: (I mean an offline version... at least initially.)
December 09, 2017, 12:25:01 AM
Fox: Now that I have thought about it a bit more, would I be right to assume that GSHC would be one of the most interesting websites to administrate, or no? It's sad to see not much going on with it. == I almost want to make a concept website at some point. :D Anyway, how is everyone doing today?
December 06, 2017, 12:12:59 AM
Fox: Like... Start using Github or something... Do like how many of those other projects such as Citra (WIP 3DS Emulator) does. Etc.
December 06, 2017, 12:08:12 AM
Fox: No idea. I just wish OpenGoldenSun would release it as unfinished, but oh well.
December 05, 2017, 06:52:09 AM
MaxiPower: Bummed out that the open golden sun project is dead it seems with no actitivy in close to a year at this point. Is there any hope left in any other projects?
November 27, 2017, 10:25:28 AM
Fox: (When I say research, mainly refering to the data in the game, though checking websites can count to a degree.)
November 27, 2017, 09:52:27 AM
Fox: Maybe. But Dark Dawn is meh, hahah... I still research it, though, because data can be interesting.
November 27, 2017, 05:28:36 AM
Portakin: I'm here! This game is underrated!
November 25, 2017, 08:03:23 PM
Fox: .... and the email listed in that post makes me think we should just make a new rules topic with most of the same information. (So the old ones can be sort o archived.)
