- # DL animation format
- # XXX - collision with most `mips' magic
- #
- # I couldn't find a real magic number for these, however, this
- # -appears- to work. Note that it might catch other files, too, so be
- # careful!
- #
- # Note that title and author appear in the two 20-byte chunks
- # at decimal offsets 2 and 22, respectively, but they are XOR'ed with
- # 255 (hex FF)! The DL format is really bad.
- #
- #0 byte 1 DL version 1, medium format (160x100, 4 images/screen)
- #>42 byte x - %d screens,
- #>43 byte x %d commands
- #0 byte 2 DL version 2
- #>1 byte 1 - large format (320x200,1 image/screen),
- #>1 byte 2 - medium format (160x100,4 images/screen),
- #>1 byte >2 - unknown format,
- #>42 byte x %d screens,
- #>43 byte x %d commands
- # Based on empirical evidence, DL version 3 have several nulls following the
- # \003. Most of them start with non-null values at hex offset 0x34 or so.
- #0 string \3\0\0\0\0\0\0\0\0\0\0\0 DL version 3
- # SGI and Apple formats
- 0 string MOVI Silicon Graphics movie file
