Similar to Tret (http://forum.goldensunhacking.net/index.php?topic=2836.0), GS2 also has some stuff that'll replace the tile at the player's coordinates. When out of bounds, this could edit other things. (It might get complicated, though.)

I haven't yet found a successfully exploitation result yet... (My assumption is it might only be good for TAS if there is something?)

There's one big thing to note, though... if you get off the tile that gets edited, it gets changed back to what it was.

Tiles are stored/grabbed from here:
02019118 = Approximate section for tiles grabbed.
02019124 = The tile gets stored here so it can change to whatever's here when you get off the tile.

Event ids to look at:
0x50 = 0000019C, 000001A8
0x51 = 0000019C, 000001A? ; ???
0x52 = 0000019C, 000001A? ; ???
0x53 = 0000019C, 000001A? ; ???

0x5A is also another, but it wasn't listed in the Retreat Map's event list. (Map 85 was what I was looking at.)


Tiles that are edited:...
Look at the pointer at 020301A4.
[020301A4]+0x8000 for the first tile to be changed.
[020301A4]+0x8200 for the second tile to be changed.

If OOB to the north -=0x200
If OOB to the west -=0x4

Remember kids! Before you go on that interview, remember to wash your hands in teawater! *Coughs on hand* (Excuse me, I just coughed up a little teawater, so they're still clean!) You wouldn't want that hiring manager to be unimpressed.

May the force be with you!
Shoo! Why does it smell in here?
Maybe that's the wrong kind of force. *smirk*

1) If there were a way to find a credits warp, of course its in Airs Rock.

2) This is unrelated to the sprite table being filled up after a retreat warp, correct?

Well, of course! Before this topic, I kinda was messing with Walk-through-walls feature... and noticed something strange about how tiles are set... when getting off tiles/going to another unreachable location... so then that's when I looked into what was going on...
That of course, was originally in a room Retreat doesn't work, so I looked at a Retreat map a bit later to notice this thing...

---
Correct, I think... as I don't think this has anything to do with sprites.... just tilemap/map code?

Fox: Thinking.... meme topics.....    Isaac: Stop calling me a sack! Also, don't call me sick either!

Fox: Really don't see the point in the Crystal or even the crown conversation, but whatever... (I mean, if you want to do it, then just do it. - Doesn't need to be at GSHC, because there are no longer clan leaders at GSHC.)

squizzy44: We all need to band together to take down Crystal.

Fox: Your clan?  You can't edit it manually, so you have to tell an admin so they can do it. There's actually a topic for when you pick a clan... but uhh... I've no idea if an admin will see it via that, though. (Kain will certainly see id you ping him on GSHC Discord.)

squizzy44: How do I change my position on my profile? I haven't used the site in nearly 10 years...

Fox: I still wonder if a Tret glitch for speedrunning exists... I don't think I looked into if the PC was on one of the other layers. (Which basically the second layer edits @-0x200 instead of @-0x100... in the event you are going up (y-axis) out of bounds.) Hm.

Fox: Not me.

Salanewt: I don't know of any, although if there were then we'd have to send it as a patch file. I think someone is working on it at least!

MaxiPower: no such thing exists

reeZ931: Anyone have a golden sun rom where you can play as saturos and menardi properly?

Fox: It would explain why everyone leaves so quickly after taking our bananas.
March 24, 2019, 10:36:10 PM
Fox: Wouldn't bananas increase agility the more you have? Like... Diddy Kong Racing reference.

Average Wind Seer: Banana: Restores 50PP to user. Restores 40PP to Isaac if Jenna uses this item.
March 22, 2019, 09:57:53 PM
Salanewt: Lol. I mean, I am thinking of adding a banana item to GS so...
March 22, 2019, 09:48:42 PM
Fox: Ooh! Sala's back!  I think he wants a banana.  All this banana talk must have attracted him.
March 22, 2019, 08:56:52 PM
Fox: :O I just notice I have no Coins to buy bananas with! (You know, the coins feature this forum has.)
March 04, 2019, 08:45:44 PM
Fox: Aw.  I kind of want to suggest dressing up in a banana costume.  No wait, that's a bad idea.
March 04, 2019, 04:24:10 AM
Average Wind Seer: *angry gorilla noises that roughly translates to "Stay the [redacted] off my island and don't touch my [redacted] bananas"*
March 04, 2019, 03:06:07 AM
Fox: Gosh. This is like playing whack-a-mole! What's taking you so long with the bananas?! :D
