Taito Legends Power-Up is a compilation of classic Taito video games released for the PlayStation Portable system. Patterned after the Taito Memories series for PlayStation 2, Power-Up marks the first release of the franchise on a portable gaming system. The Japanese version is called Taito Memories Pocket and has sixteen games. The western versions remove Rainbow Islands Extra, and replace it with six other games, for a total of 21 games on the western compilation.

Taito Legends Power-Up features 21 (16 in Japan) different games from Taito's back-catalog of arcade titles. Some of these games have appeared on the Taito Legends console releases, while others are exclusive to Power-Up.
