If you click on this image, you see that Rise of the Robots was announced in this catalogue as "DV Required" - You needed the Digital Video Cartridge to run this game. The extra memory was used for the backgrounds including the same effects as the Gremlin team had implemented in Litil Divil, where the mazes had actual moving backgrounds that were never possible without the extra memory of the Digital Video Cartridge. What happened?
The programmer of the CD-i version of Rise of the Robots, Pete Dabbs, explained: "I've always found it a bit weird that I did do two "final" versions, one for DV and one not because there was a massive rush on at the end of the project and I didn't have time to fit code for both into the same thing so it looks like only the non-DV version got released and got packaged as requiring (or using) DV??"
If we look at the back of the jewelcase of Rise of the Robots, you'll see it sais the Digital Video Cartridge is required to play this game.
While this is actually a base-case title. So there might be a CD-i prototype somewhere around with an unreleased version of the 'Digital Video on CD-i' version of Rise of the Robots!
It appeared more often that Philips was sluggish with the naming of CD-i products. Do you know more examples? Most of the times it is just a typo, like with Lost Eden, which has the base-case "compact disc interactive' on the front while it should actually be a 'Digital Video on CD-i'
[Thanks, Pete Dabbs]
