A tileset is a set of graphical tiles used in roguelikes to substitute the regular ASCII graphics, creating a GUI. It works by defining a set graphical tile for every symbol and object in the game. Graphical tilesets are often beneficial to new roguelike players who are not accustomed to the usual graphics-free style roguelikes are presented in. NetHack's DevTeam has created an official tileset for their official graphical client, and Angband has exceptional support for tile customization. Using tilesets provides the same top-down view as ASCII graphics and should not be confused with separate clients using 3D graphics (such as Falcon's Eye), which are a separate system entirely.
NetHack 3.6.0 tileset
NetHack 3.6.0 has made some changes to the tileset layout. The default 16x16 tileset for 3.6.0 appears below. You can place the mouse over any tile and a tooltip will describe it. A click will go to a relevant page.
The default tileset for NetHack 3.4.3 appears below. You can place the mouse over any tile and a tooltip will describe it. A click will go to a relevant page.
At this writing (12 Dec 2015), most third party tilesets are not updated to NetHack 3.6.0. This program can convert the file, if it is in BMP format, and make it mostly usable with 3.6.0; it can also aid the author in updating his/her tileset.

Options to set a tileset
The option tile_file sets the path to the tileset; tile_width and tile_height set the width and height in pixels of each tile. Default settings for tile_width and tile_height depend on the user interface; usually both default to either 16 or 1/40th the width of the tile map (1/40th is correct for the default tileset and most third party tilesets, but Geoduck will need to have at least tile_height set).
