Unlike movies, game credits are often hard to find, or overlooked. Since most players don’t finish their games, developers try to place them in menus or make them interactive to have the players at least glance at them for a second.
In Raving Rabbids: Travel in Time, they’re hidden in a subscreen of one of the game’s “bonus images” menus. You’d have to know they’re there to find them!
Since I happen to have programmed the rolling credits, I saved the source text file for this occasion.
