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: That would be cool to have, yes. Where the text in the ROM is uncompressed. - The huffman compression used in the gba games is not used in the nds game, so perhaps that may be one reason it wasn't done. I think it is some generic compression thingy. If someone did do it (and make the entire ROM uncompressed), perhaps I would be more inclined to work on my dark dawn editor. Hm?

KyleRunner: Could someone please create a GSTOOLKIT compatible with Dark Dawn? I'll try to translate that one to my language as well (as I did with the first two games).

Salanewt: Okay, minor announcement I guess. We just looked over some pre-release footage of GS1, and noticed that one of the unused and unlisted animations we discovered in GS2 (and GS1) plays in that footage. "Brine" is actually an early Fizz.
