Activision used to distribute demo disks of their games. Presumably for retailers to use on display computers. The disk could be loaded and would cycle through several pieces of software, auto-playing them, with a promotional blurb as each loaded, and hopefully enticing potential customers to buy their games.
This disk has seven excellent games, which I looped though three times. (The gameplay is identical every time.) Their start-times:
1:26 Decathlon
5:47 H.E.R.O.
10:44 Toy Bizarre
13:36 Beam Rider
17:49 ZENJI
20:48 Pitfall
23:45 Pitfall II
For the second loop, the below times are 15 seconds before the game finishes loading, should you want to read the promotional text that's displayed while it loads:
27:34 Decathlon
31:55 H.E.R.O.
36:51 Toy Bizarre
39:44 Beam Rider
43:58 ZENJI
46:55 Pitfall
49:53 Pitfall II
This is played on an emulated NTSC (60Hz) C64. Toy Bizarre plays noticeably faster on an NTSC machine — I'm more used to it at PAL speeds. Pitfall is an odd one in that, on a PAL C64 the trees are rendered in a multicolour mode with green leaves, but on an NTSC machine the entire tree (trunk and leaves) is rendered in brown, with a cross-hatch shading effect used for the leaves. I'm not sure why it was done this way. It could be a bug, but I would've expected NTSC C64's would've been their prime testing platform. Possibly it was a shading trick that worked well on NTSC C64's, but they decided they had to do something else on PAL machines, as alternating high-res pixels tends to cause ugly colour-banding effects with RF input into PAL TV's of the day. (On modern RGB displays it looks fine.)
You can see this same demo disk being played on an emulated PAL C64 here, and see the quite different look of Pitfall 1: • Activision Demo Disk #7 — Decathlon, HERO,...
Three of these Activision Demo disks are preserved in original .g64 disk-image form at archive.org, as a part of the C64 Preservation Project 10th Anniversary Collection. (Link provided below.) This disk is named as disk #7, but in photos of the physical disk I've seen on auction sites it's named Activision Demo Disk 1.
I'm not sure I ever want to actually play Decathlon these days. It's an excellent game, but it's such a renowned joystick destroyer. Most of the games I've played and recorded GIF's of the gameplay, which I occasionally post to social media. Toy Bizarre is one that I also recorded footage for YouTube: • Toy Bizarre (C64 VICE 60Hz no commentary)
