Format details

NEOchrome files have a 128-byte header, followed by 32000 bytes of uncompressed image data, for a total file size of 32128 bytes.

NEOchrome images are 320×200 pixels, with 16 colors.

The format may seem to allow for other video modes, and other image dimensions. However, such files are generally not supported, and are probably not valid.
