Booter versions of AGI games
Donald Duck's Playground
Donald Duck's Playground is an adventure game that was originally released for the IBM PC as a booter on a 5.25-inch double-density floppy disk with the total capacity of 360KB (40 tracks, 2 heads, 9 sectors per track). The game uses AGI version 2.001.
On the disk there exists directories that are equivalent to the logdir, picdir, viewdir and snddir in the DOS-based AGI games. Each directory entry is a (sector,offset) pair that indicates where on the disk is the beginning of the resource. The format of each entry is:
Byte 0 Byte 1 Byte 2 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 . . . . S S S S S S S S S S S O O O O O O O O O
where S is the sector number O the offset in that sector. Actually the sector number is not the absolute sector but an offset that is added to a base sector for all game resources. This base sector is the beginning of the DOS VOL-equivalent.
