Huzzah! Tis' nice to see that you're also going to include magazine coverdisks (one of my FAVE things regarding the Amiga) in this project!
Thought I'd remind you about two other AP disks that haven't been mentioned once:
Nipper Vs The Katz. This came on the first disk of AP32 and was designed as part of a competition involving HMV's "Level One" shop, and you could win £1000 and/or some other stuff with it! It was non DOS-readable.
The other is the Cannon Fodder disk from AP31. This allowed you to select from four different levels (with different features in each of them) from a menu (much like the AP45 CF2 demo, really) and also offered a whole quiz game exclusive to the disk!
And the AP13-1 disk also contains a demo of Wizkid, Twist forgot to mention.
The One also had a Cannon Fodder demo disk in July 1993, although this one had no menu - you played three (or was it four?) levels back to back. And there were no extras on the disk (so no quiz, etc). Their Rick Dangerous II demo was also known as "Rick Dangerous 2½", as it is known in its ADF (containing just the game, no T.O. menu) on the TOSEC set.
It'll be cool to see proper working dumps of the Zero disks as well, some of the ones available from Nth Dimension (particularly the ones in DMS format) don't work at all (did they even dump all the tracks on them?) and so are next to useless.
