It was initally defined and implemented by the <tt>in_wsr</tt> Winamp plugin. Its format is based on the ROM header format, with files expected to be a multiple of 64 KiB in size. However, the footer at the end of the file is 32 bytes long, not 16: {| class="wikitable" |+ Header contents |- ! Offset !! Length !! Contents |- | $00 || 4 || Magic string: <tt>WSR...")

In the case of Screen 2, one can use the Display Control port to configure if the window should render only the tiles inside of it.
