Page under construction. Not much to see here. Meant to be both a tutorial and documention for 2D graphics (aka anything that uses NCG, NCL and NSC). For ease of comprehension, the phrase "game tile" will be used to refer to the 16x16 tiles the game uses for its levels and the phrase "hardware tile" will be used to refer to the 8x8 tiles that the game tiles are made out of.
Todo:

This is more of a table fest than a tutorial. Each of the tables here are important though. Not sure what to do about it.

Fill in the TBAs

This will probably be split into multiple articles later on. It's just going to be way too large otherwise. Might also help mitigate the table problem.

1. Tilesets

Tilesets are used to build your level's layout.

1.1. Objects

Objects are what you place inside of levels. There can be up to 256 of them in a tileset and they each have an ID between 0 and 255. They are composed of one or more lines, which are themselves composed of any number of game tiles. Not every row needs to be the same length. If any of the rows in the object has no game tiles, the entire object will be empty.

1.1.1. Map16 Tile Number

This is the game tile number from the map16 that the selected game tile uses. Starts at 0, left to right, top to bottom. Set to -1 for an empty tile. Alternatively, selecting the desired game tile(s) on the map16 will add them to the selected object after the selected game tile within the object, and click the Empty Tile button to add an Empty Tile.

1.1.2. Control Byte

This can be anything between 0x0 and 0xFF. However, only eight values are truly useful, with the others being redundant.

Value	Behavior
0x0	Normal
0x1	Repeat X
0x2	Repeat Y
0x3	Repeat X and Y
0x80	Slope control (up-right) (acts like 0x0 if not the first game tile of line 0)
0x81	Slope control (flipped, up-right) (acts like 0x1 if not the first game tile of line 0)
0x82	Slope control (down-right) (acts like 0x2 if not the first game tile of line 0)
0x83	Slope control (flipped, down-right) (acts like 0x3 if not the first game tile of line 0)

In truth, this should probably be treated as a bitfield:

Bit	If 0	If 1
0	Normal	If first game tile of line 0, slope control. Otherwise, normal.
1	Unknown	Unknown
2	Unknown	Unknown
3	Unknown	Unknown
4	Unknown	Unknown
5	Unknown	Unknown
6	If normal, nothing. If slope control, up-right slope	If normal, repeat X. If slope control, down-right slope
7	Nothing	If normal, repeat Y. If slope control, flipped slope

1.1.3. Descriptions

The "Create Descriptions" button will add a Description field for each of the objects in your tileset. The description you add will be displayed as a tooltip for the object in the level editor. This is purely an editor feature, it serves no purpose in-game. The descriptions are stored in the 00DUMMY file.

1.1.4. Set End

This will delete every object after the object you have selected.

1.2. Map16

The Map16 is the tilemap of a tileset. This is where the the hardware tiles from the NCG file are arranged into game tiles to be used in the tileset objects. Tileset 0 (Jyotyu) has a Map16 of 256 tiles, tileset 1 has a Map16 of 768 tiles and tileset 2 (Sub Nohara) has a Map16 of 512 tiles. NSMBe presents this as a 16 game tile wide grid. The other of the game tiles in the grid in terms of ID goes from left to right, top to bottom.

1.2.1. Draw

Draws the tiles that is selected in the NCG that can be seen to the right of the Map16. This will be cropped if it is drawn to an area that is smaller than the selected data or will be repeated if drawn to an area that is larger than the selected data.

1.2.2. Horizontal Flip

Allows horizontally flipping one or multiple hardware tiles by selecting them. Note that tiles won't be flipped in relation to the center of themselves, but rather in relation to the center of the selection.

1.2.3. Vertical Flip

Allows vertically flipping one or multiple hardware tiles by selecting them. Note that tiles won't be flipped in relation to the center of themselves, but rather in relation to the center of the selection.

1.2.4. Copy

Allows copying one or multiple tiles by selecting them.

1.2.5. Paste

Allows pasting copied data. This will be cropped if it is drawn to an area that is smaller than the copied data or will be repeated if drawn to an area that is larger than the copied data.

1.2.6. Change Palette

Increases by one the palette used by one or multiple tiles by selecting them. Wraps around to the first palette for tiles that currently use the last palette.

1.2.7. Undo

Reverts last action.

1.2.8. Redo

Reverts Undo.

1.2.9. Show Grid

Enable/disable 16x16 grid.

1.2.10. Randomization

Certain Map16 slots in certain tileset slots have randomization. When a tile from a randomized area of the Map16 is placed in a level, a random tile from that area will be chosen. See this table for more details on which tilesets use randomization and how.

1.2.11. Harcoded Jyotyu Map16 IDs

These Map16 IDs have a special hardcoded behavior.

Map16 Tile ID	Behavior
0	No special behavior, but NSMBe's level editor wrongfully acts as if this were ID 1 and draws this on every space that doesn't have a tile placed down.
1	This tile is displayed everywhere that doesn't have a tile placed down in levels. Always leave transparent.
2	Unknown (camera-related). Always invisible.
3	Unknown (camera-related). Always invisible.
4	Unknown (camera-related). Always invisible.
5	Unknown (camera-related). Always invisible.
6	Unknown (camera-related). Always invisible.
7	Unknown (camera-related). Always invisible.
8	Unknown (camera-related). Always invisible.

1.2.12. 3D Tiles

While the vast majority of tiles are two dimensional, a small number of map16 slots in specific tileset slots are hardcoded to instead display a specific NSBTX file from the polygon_unit folder. This is the case for quicksand, pipes, water, and generally any other tile that has the ability to appear on top of the player or other 3D models. Here's a table that shows this in more detail.

Tileset Slot	Map16 Slot	3D Tile ID	File	Bitmap	Palette	Description
Jyotyu	112	TBA	I_dokan.nsbtx	I_do_lu	I_dokan:0	Upwards facing green pipe (left)
Jyotyu	113	TBA	I_dokan.nsbtx	I_do_ru	I_dokan:0	Upwards facing green pipe (right)
Jyotyu	114	TBA	I_dokan.nsbtx	I_do_yoko_lu	I_dokan:0	Leftwards facing green pipe (up)
Jyotyu	115	TBA	I_dokan.nsbtx	I_do_yoko_ru	I_dokan:0	Rightwards facing green pipe (up)
