So this is a thing.

Frostfx made this convenient image to help explain the glitch: https://images-ext-1.discordapp.net/external/1t7y1yv3glyOzJNRFdQFPmDmP5OwcqooThpMibEnCCE/https/i.imgur.com/mo7Dg33.jpg

Not exactly a "river," if going by the graphics, but that looks amazing!

Happy
Alex  Continental shelves are shifting!  And in an unexpected way, no kidding!

I feel like I want to call it The Magic Roundabout. (Referencing a UK cartoon, I think.) ... (And also secretly references something I was part of on RuneScape years ago. :P A clan I joined was named Skilling Central, and they changed their name to The Magic Roundabout, eventually, the clan "died", and owner moved on to another clan: The Round Table. (King Arthur reference, I assume.) I also followed, and that clan is still here today... Though, I haven't been on RS much lately.... I do want to eventually get back to it, but I was planning to hold off until AT LEAST the release of the bank rework. :/ )

---

Seems to be a 16-pixel margin? 0x1F00-0x1F0F

Map when not scaled is 0x2000px x 0x2000px, I think... but with the scaling, likely doubled... (Referring to current x and y location, since the top of the screen is shorter/bottom is longer.)... so 0x1F00 being right under the half way mark is interesting... (I feel like some rounding thing could be going on... like adding 1 when a number is negative, but I have no idea. Can probably look into it, though. Expecting it to be as simple as a breakpoint write on tilemap ram data. *crosses fingers*)


But first:  Going left/right with Map view open... (using auto-update).... And I'm not sure I understand this...  (Attachement... the column in the middle/at the bottom... when I walked left.) Did not need an encounter to see this... (But I imagine if it is the same as the glitch above.. then you probably would need one to "abuse" it?)
(Also see the same "flickering" on the left side when going right. (First column in map view.))

Almost forgot:  I should test it without messing up the flags... sso this is with messing up storybook flags.... in case it doesn't happen in cannon.

Maybe it is over-analyzing, but it doesn't mean the information is useless.

He's correct about the map being split up, but the sections are 256x256 pixels, or 16x16 tiles that are 16x16px.  I don't know what's happening with this glitch beyond that.


Edit:
FYI there's a full rip of TLA's world map as stored in the game data (except some tilesets are incorrect) available here (8192x8192px, 10.8MB)

I could understand why the graphical glitch might happen because of how the graphics rendering is optimized (see Fox's post above), but the fact that the collisions are incorrect too baffles me.

@FYI: That's cool, but a lot of those tiles are incorrect. (Since the tileset is switched.) ... Um? Not sure why the link sometimes doesn't work? Says it contains errors. Might be due to memory, though.

Anyway: From gsmagic (At least my version.):  ...  https://i.imgur.com/7zd1ibu.jpg (Prox/Mars Lighthouse area.... Gaia Falls... Snow areas... etc.)
Looks like I got some tiles wrong! (I lack water where it is needed.)  Thank you for posting that link!!
(I think I might know why.....) Fixed: https://i.imgur.com/mRzaKyi.jpg (And yes, some of the water tiles are snow in the second huge segment = That is correct. It'll look like water when you're off those tiles, though.)

I know there's a collision tileset (Just for World Map.),... so isn't the indexes that are used for graphics also used for that tileset too? So that would kind of make sense... However, I kind of forgot what I researched a long time ago, so....

World Map tilemap is pasted at 02020000. (Instead of 02010000 as normal maps do.) - 4 square maps are loaded at a time.
zzyyxxxx
zz = Can effect the tileset used.
yy = Event ID
xxxx = Graphical index , but also collision index?(Not confirmed?) (World Map only?) (May not necessarily be 16-bit, but for example...)

Update:  Been too lazy to put that breakpoint in. :/ (It's possible I may even have the function already documented, even if I don't have its contents documented.)

Thanks for the map Atrius. Having explored that area using the first flight cutscene glitch its really cool to actually see what is there :)

But your map also reminded me that there is another point in the game where the overworld is updated - after you fix the boat and set Briggs free.

Getting an encounter with y-coordinate as indicated in the image will cause the bridge to un-fix itself (EDIT: its actually way more lenient, there's a large band of y values than work south of where I am standing). I can't see any other errors caused in this occurrence of the glitch. Of course, opening the menu and closing it again will fix the bridge - as illustrated in this gif: https://gyazo.com/01fe839247061ad159edd296e3fba40b

I guess then the next question is this - when Venus lighthouse is lit at the start of the game, are those cutscenes happening on the copy of gondowan far to the west of the world map? Or is it happening within the world map but having tiles updated?

Attachment: An image showing where a flag check is done, and how two map sections (side by side) are copied over. (For the Contigo area.)

In map code initialization....

Arguments: srcx, srcy, desx, desy
No size values or anything, so the whole square (16x16 tiles) should be "copied" over...  By putting a file number in the 03001448 list.

Calls a function that hasn't really been documented, but is in an expected area.

0802BD08

r6 = 02032640 = screen x
r7 = src position
r12 = 02032648 = screen y

to be continued?

---
Not sure where glitch occurs yet, but I now at least have something about this function in my doc.

Fox: Even just plain Editor work can make some difference. = At least these forums are indexed on the Search engine. I was also curious about whether to um... go through all the topics on these forums and take all the important stuff out/placed into a folder for a bit of organization. Would be a bonus since if something ever happened to this forum, or if we ever wanted to start afresh again, it wouldn't be that difficult to do so.
December 24, 2019, 09:23:03 PM
Fox: One thing is for sure. This place has become completely dead. (Mostly because of Discord.)  = I don't think much will happen with this forum unless I, Salanewt, or someone else does a thing.
December 24, 2019, 09:18:05 PM
Fox: Probably not?
December 24, 2019, 06:51:08 PM
Luna_blade: I suppose this is the last Christmas of this forum? 
December 24, 2019, 06:50:51 PM
Luna_blade: Yay thanks for the coins
December 19, 2019, 04:39:45 AM
Fox: Okay, another thought... "gsmagic" could be the code name/project name... and "Golden Sun Magic" could be the more formal official name... (As in using both names.)  -  I still need to look into these other games as well... so who knows if it could be better to call it Camelot Magic if those should ever be supported to a decent standard.  Would probably be a long time from now, though. As I can be pretty lazy.
December 18, 2019, 10:01:39 PM
Foreclosure: gsmagic is fine
December 17, 2019, 05:44:32 PM
Fox: Also. I call my program "gsmagic" and not "GSMagic" =P (Not asking for correction/I being silly)... Had to call it something, so picked something short.  Maybe I should rename it to Golden Sun Magic later. *shrug*
December 17, 2019, 05:35:04 PM
Fox: (And "Golden Sun" instead of "GS" to reduce confusion that would likely not be there anyway... when "Golden Sun" doesn't take up much space to start with. (Imagine being new and thinking GS meant GameShark, or some other oddity. Ew.)) - All just thoughts...I'm still going with most of this not mattering that much, though.
December 17, 2019, 05:12:55 PM
Fox: "Misc. GS Hacking" = That name looks odd, so I'd probably just go with "Golden Sun Hacking"
December 17, 2019, 05:08:05 PM
Fox: I tempted to also suggest the Editors can go in the first category. Since the Editor is the reason this place exists in the first place. (I think.)
December 17, 2019, 04:53:19 PM
Fox: (combined = Not meant to be taken literally... but rather.... to generalize things more, since it apparently looks like we don't need the extra space no one is using.)
December 17, 2019, 04:48:49 PM
Fox: Worse still... we've only used those for Golden Sun content.... and there's not much there.
December 17, 2019, 04:45:53 PM
Fox: E.g. Maybe everything in "Assets & Discussion" could be combined with "Creative Works".... I don't feel like sound and art apply to general hacking anyway... that only comes into play when you have tools to insert them.
December 17, 2019, 04:40:26 PM
Fox: categories and/or forums
December 17, 2019, 04:36:48 PM
Fox: Everything else seems to be about right, though. Perhaps some categories could be combined(?), but doesn't really matter that much.
December 17, 2019, 04:33:03 PM
Fox: (I still think The Community section fits best at the bottom. =P)
December 15, 2019, 05:10:04 PM
Salanewt: Heya! I'm planning to get the demo up today, but if you can't wait then it's already available on the Discord.
December 15, 2019, 04:12:27 AM
Fox: (Then sell the badges on the Trade Center for a very high price... and give a lot of active people coins to buy them with, so they can basically transfer the coins to me if they want something... Gosh I could be a naughty hoarder. =P)
December 15, 2019, 04:06:19 AM
Fox: I'd buy up all the stock for each item too... but man... I think I'm too lazy for that. =P
December 15, 2019, 04:01:24 AM
Fox: There we go. That should be all of them.
December 15, 2019, 03:25:32 AM
Fox: Duplicates will still show up as separate entries on the profile as well. Interestingly enough.
December 15, 2019, 03:18:25 AM
Fox: (Well, one of each badge, at least.)
December 15, 2019, 03:18:08 AM
Fox: Now I can buy up the whole shop. :3

Foreclosure: I sent 2 thousand coins for ya bro
December 14, 2019, 01:31:38 AM
Fox: In my opinion, even with the old system where it was set up so you could only coin people once per hour... I think it would have been far more fair if we could have also coined ourselves hourly.... since people have favoritism for certain people.... I feel like that could mitigate it some. At least to get badges that people care about the most. - Unlimited coining sounds like a step further than that, which is interesting... :)
December 14, 2019, 01:12:00 AM
Fox: Do note, that people can't coin themselves... but I feel if you got someone who's willing to transfer the coins you give them back to you... it is as though you have that coin option on yourself anyway....
December 14, 2019, 01:07:29 AM
Fox: Go to any of my forum posts, look for where it says Coins... under that, you'll see [increase] , clicking that will give me coins. You won't lose anything for doing so. Click it as much as you like... Under that, you should see Send Money (a faster option if you got the coins). Use that link to transfer your coins to me of any amount you want. (e.g. Put in 2000, means I get 2000, you lose 2000... but if I've already given you 2000+, you don't really have to see it as actually losing anything.)
