Chain Demo is a demo by EGS of Galaxy Soft.
All copies of this demo are broken. The first part is loaded using standard files, but the final part is loaded sector by sector by talking directly to the fdc. These sectors exist on track 40 and 41, but no copies have these tracks, so the final part is missing.
Release date: 1991
