The second installment of the PlayStation series features Mappy (1983), Xevious (1982), Galaga sequel Gaplus (1984), Grobda (1984) (a Xevious "spinoff"), Dragon Buster (1984) and Super Pac-Man (1982) (in western versions), and Cutie Q (1979). Although Cutie Q is only playable in the Japanese version, its code can be found on the American release of this compilation. It enjoyed similar success to the original, and contained a similar "museum" mode. The Japanese version also features Bomb Bee (1979) as a hidden game. There is a glitch in this volume where in Dragon Buster the high score is not saved properly. It is shown in the record book, but does not appear in-game. The default hi-score is 10,000.
