Why does it need so many discs, lol.
Let's do some simple math:
763 360k diskettes contain 763*360 = 274 680 KB
One MB is equal to 1024 KB: 274 680 / 1024 ~ 268 MB, which is a pretty normal size for a full-length AGS game.
Right you are, DrSlash.
I looked at the size of the uninstalled 2nd Demo file (in MB), multiplied by 1024 (to go from MB to KB) and then divided by 360 (to go from KB to the number of single-density 5¼" diskettes).
I think it worked out to be like 759.xyz diskettes, so I just added a few more knowing full well that not every diskette would use the complete 360 K of disk space available on it...
It'll take a while to install (9½–10 hrs), but on the plus side, it supports CGA and EGA !
