The game uses AGI version 2.001. | ||
===Directories=== | |||
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: | |||
<pre> | |||
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 | |||
</pre> | |||
where S is the sector number and 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. | |||
===Volume (VOL) format=== | |||
The [[AGI/Specifications/Formats#Vol2|volume format]] is exactly the same as in DOS-based AGI v2 games. | |||
Further, most of the game resource formats are also identical to v2 games. An exception is the SOUND resource format that [[AGI/Specifications/Sound#AGI v1.12 sound format|carries over from earlier AGI versions]]. | |||
