REQUEST: Find out in what way Area's are linked in DPP

[RedJiggly]

Hello there everyone,

I myself am mostly a Glitch Researcher, and I've been researching the Void for some time now. I do not know if everyone of you knows what the void is: but mainly it is the Black Area surrounding Indoor area's. By abusing a glitch called the 'Tweaking Glitch' you can get trough a door from the back, and with it enter the black area surrounding this Indoor area.

On Platinum and HGSS this has been fixed in some extent, All Mystery Zones are Solid from themselves so you cannot travel trough them. However, on Diamond an Pearl we can use them to travel mayor distances, and people have found ways to use the Void to get to Shaymin, Darkrai and Girantina early in the game and without the use of Events/AR Cheats.

If you want to know more about the void, I suggest you would look on Bulbapedia or on Hall of Origin. There is much informatino and explanation of stuff.

Now onto the reason I've created this topic. There are many unsolved questions about the void: Why does it exist, and when are what area's loaded where in the void. What is of big interest at this moment is what area's are next to another area. Somewhere in the ROM's code would be specified what area's are loaded next to eachother. I know the following about Area Loading in Gen4:

There are 9 area-tiles loaded in memory. Each area-tile is made up of a square of (32x32) tiles.

You are on the middle tile. When you cross over the middle of the middle tile,the three old ones behind you are discarded, and three new ones in front of you are loaded.

However, I'm wondering where and how in the game code is set what area-tiles are next to eachother. I see two ways this could be done in the game programming:

1)Each tile has some kind of X and Y value, the game looks at the tiles with an X or Y value next to the current tile

2)In the data of each tile is set what tiles are adacent to the curent tile. This would also mean that you don't have to get in the same area baack as you've started from when going back the same way.

Another thing to note: The void seems to change when some specific flags are set by the player(such as Items recieved, gyms beaten, honey trees slathered).

So, I'm not sure if this would work, but I'm asking the help of one or more people who know how the ROM is fit together, especcialy the Area-Placement part. The final goal is to understand more about how area's are loaded, and maybe even make it possible to create an automated map of the void.

I hope this post is clear to you. If you have questions about anything, I'm willing to help :rolleyes:.
