extension pixel w/h size in bytes imgscan.prg version<br />
*.RWL 320x200 64000 < 1.84<br />
*.RWH 640x400 256000 < 1.84<br />
*.RAW 640x200 128000 => 1.84<br />
<br />
Image date is always 256 shades of gray, where 0=white and 255=black <br />
<br />
From the IMG scan v1.84 addendum:<br />
Raw data files have been standardized to 128000 byte files for all resolutions. This<br />
means that a raw data file (".RAW") can be loaded and saved in any screen resolution. <br />
The files are saved as 640*200 and 8 bits per pixel.<br />
