Rather a good telling here by co-creator Rand Miller, starting with the discovery of the possibilities of HyperCard… one in the War Stories series which might be worth picking through.
… behind the scenes of the development of one of the best selling PC games of all time, Myst. The HyperCard-developed title ran into some snags when trying to run on the CD-ROM format… Rand and his brother, Robyn, compressed the image and audio data as much as they could so the game could run smoothly on 1x CD-ROM drives.
