Video content in Jampack discs typically included trailers for games or walkthroughs for sections of popular games.
Some discs would include special game save files that would save to your memory card and often unlock everything in the game or specific characters, weapons, or levels. Most of these features were brought over from the PlayStation Underground game magazine, like the "Cool Moves" section, and the list of games being called "The Vault".
They were released by season, with a winter, spring, summer, and fall issue coming out each year.
