bin	Various binary data
col	Tileset collision

json	Various json data
nfyp	Necrofy project settings
nfyp.user	Necrofy project user settings. Contains settings that are specific to the current user and do not affect building the project.

tlms	Sized tilemap. The width and height of the tilemap is stored in the first 4 bytes of the file.

Special files and folders

Path	Type	Description
project.nfyp	File	The main project settings file. Other names for this file are possible, but this is the default.
project.nfyp.user	File	The main project user settings file. Must be the name of the project settings file with ".user" appended.
base.sfc	File	The base ROM. All project files will be applied to this ROM when building.
build	Folder	All project build artifacts are stored here.
Demos/demo#.json	File	Demo recording data. "#" can be any non-negative integer, but 0-3 are the only values that are supported by default.
Editor	Folder	Contains settings files for the various editors in Necrofy. Putting these files in a project will override the defaults.
Level Title	Folder	Various files in this directory are required for the level title editor. No special handling is applied to these files when building.
Levels/#.json	File	Level data. "#" can be any non-negative integer.
Misc/Passwords.json	File	Password data.
Sprites/Graphics@020000.gfx	File	Default sprite graphics data. Required for rendering sprites in the level editor and sprites editor. No special handling is applied to this file when building. The pointer in this filename can be changed without breaking this editor functionality. This file does not use the "gfxs" extension because these graphics do not need to be contiguous with the extra sprite graphics.
Sprites/GraphicsExtra.gfxs	File	First extra sprite graphics. These graphics will always be inserted at the start of the extra sprite graphics data. This is generated when the base ROM already contains extra sprite graphics.
Sprites/Sprites.spr	File	Default sprite tile data. Required for rendering sprites in the level editor. No special handling is applied to this file when building.
Tilesets	Folder	Tilesets must be stored here to be displayed in the level settings. No special handling is applied to these files when building.
Tilesets/*/Suggestions.json	File	Tileset suggestions data.
