<p><b>New page</b></p><div>This is a simple video format used in some <em>Sesame Street</em> related games.<br />
<br />
File header:<br />
4 bytes - "STHD"<br />
4 bytes - version (should be 0x100)<br />
4 bytes - unknown<br />
4 bytes - unknown, usually zero<br />
4 bytes - audio sample rate<br />
2 bytes - bits per audio sample<br />
2 bytes - padding?<br />
<br />
Data is organised into chunks, <code>"GRPH"</code> for images and palettes, <code>"SND "</code> for audio. Each chunk beside 32-bit usually has one nested subchunk telling what kind of data it is: for video it is either <code>"PAL "</code> for palette or <code>"PIXX"</code> for image; for audio it is <code>"SSMP"</code>.<br />
<br />
Image (sub)chunk has dimensions in its header and stores raw data in permuted form: by VGA bank (i.e. every fourth column) where data is also 4-way interleaved.<br />
