No Scroller 2 present in AC77 disks
 

Something's not right about the two disks available at this page:

http://amr.abime.net/issue_515_coverdisks

Namely, neither of them contain the Scroller 2 program. According to the magazine, it's supposed to pop up from just booting one of the disks, but they both go to WB and show different apps instead.

Possible clones?

You're right, it's second disk, not first:

Second ADF from AMR have almost same files inside.
