ADK Damashii is a compilation of video games developed by ADK and released by SNK Playmore for the PlayStation 2 console exclusively in Japan on December 18th 2008. It was later ported to the PlayStation 4 both in Japan and internationally on February 23rd 2017.
It includes 5 arcade/Neo Geo games; Aggressors of Dark Kombat (Ganggang Kohshinkyoku), Ninja Master's: Haō Ninpō Chō, Ninja Combat, Ninja Commando and Twinkle Star Sprites. All 5 games are 1:1 arcade ports with only one small enhancement in the form of skill lists/move lists for the characters of the fighting games; nothing else was changed. They are all 2D Games and every game is for 1-2 players. The games are not slower or have any glitches the originals didn't have.
