Konami Antiques MSX Collection Ultra Pack (コナミアンティークス ＭＳＸコレクション ウルトラパック) is a compilation of MSX games released for the Sega Saturn exclusively in Japan in 1998. It is a combination of three previous compilations released for the Sony PlayStation, making 30 games in total.
Every game in the series skipped Sega's consoles, though several games released for the MSX received unlicensed ports to the SG-1000 and Sega Master System (running in SG-1000 mode) in South Korea and Taiwan. Yie Ar Kung-Fu was planned to be officially released for the SG-1000, but this port was cancelled.
