[edit] Format details
Images are 640×400 pixels, 2 bits per pixel. The image is stored as four 320×200 images, each of which is interlaced. File size is 64008 bytes. The 8 extra bytes are located at offset 32000.
It's not clear if there's a canonical color scheme, but Turbo DiGI uses the CGA black/green/red/brown palette. DGIMAC.EXE converts .DGI images into monochrome by ignoring every second bit of image.
[edit] Identification
Bytes 01 04 00 00 00 00 00 00 appear at offset 32000. The file size is normally exactly 64008 bytes.
