Ok so I did you a favor and added those tiles quickly.

OMG Fuck this. I updated my 3DS recently to the newest firmware version. Now I can't use Gateway 3DS anymore!
I wouldn't have cared, but now that NSMB2 Hacking is possible it makes me angry.

He means the bugged texture file of w1 in the map folder that can't be edited by the editor because of the error "This file is already being edited."
Of course there is no way that we could find the world map nodes there.

Use an older Revision. IIRC it is a bug that only happens in the newer releases.

The hard thing in making an editor of a game is figuring out how the game works. First you will have to figure out, how the things you want to edit in Need For Speed work. Then you need to document your findings.

Then comes the programming part, which is easier, but still not easy at all.

If it helps, I will copy the sprites we used here. Just put them like this in your level.
When entering Zone 0, the mechanism will start to loop. Every once in a while the poison water will rise and lower again.
Change this machanism to meet your needs.

I think the contrast is too high. The dark "vertical lines" are too dark in comparism to the other color.
Also, I'd make the grass thicker. It only covers the top pixels.

I don't know, why this tileset is not here anymore, but I will just repost it. (I think it was in the old resource forum)
It is some mixture of the grass from the original grassland tileset and some stone ground I made myself. There are also some tiles from the NSMB Beta in it. I would say, draw the decoration yourself, because the decoration inside this tileset looks aweful to me.

The colors aren't the best either, because it is all inside one palette. (Haven't got the original image anymore)

Area numbers always start from the current area (current area is 0)
If you make the destination area 7 in W1-3, you travel 7 areas forward. That means that you end up in area number 14, which is W1-A Area 1.

I know, this all sounds a bit confusing in the beginning, but I am pretty sure you will get the hang of it soon.

No, there is sure something that hamza does wrong.
Well, the problem is that I haven't got a clue about what's wrong. It is very likely that there is something wrong with the overlay file that is being used.

If you have problems using this editor:
Try this overlay file. This file totally works for me or  ray. If it does not work for you, you probably do something wrong when decompressing the file with the old NSMBe revision. Also, make sure you are using a (U) ROM.

I once found it. It is stored as a texture anywhere in the ROM.
I is something like a frame that gets scaled over the whole screen.

You are really talented! I hardly see any hacks that have 100% selfmade graphics.

It is just an animation. You need to know that almost everything visible on the worldmap is the model + animations. I don't know, wheter you can add pipe animations with RicBent's Worldmap editor or not. I also remember that there is some table in the overlay9_8 that toggles pipe and non-pipe animation, which means that the sound of the pipe is played and Mario squeezes like when entering a pipe. However, I currently can't find the table offsets in my and  ray's Skype conference... Dude are those a mess.
Of course I shall post them, once I found them again.
