Super Turrican (1993) is the fifth game of the Turrican (http://en.wikipedia.org/wiki/Turrican) series, popular in the times of C64 and Amiga. It features Contra-like run'n'gun action crossbred with Metroid-esque exploration-driven level design and character abilities, while also being quite colorful and having remarkable soundtrack.
EZGames69 (http://tasvideos.org/EZGames69.html) improves the previous TAS (http://tasvideos.org/2006M.html) by 3 minutes and 28.52 seconds, thanks to a glitch that allows one to clip into any wall, as well as overall better optimisation. Despite having the same name as its NES counterpart (http://tasvideos.org/2936M.html), it's not the same game. Curiously, while this version was made without Manfred Trenz (the original Turrican series designer/developer), the NES one was produced by him alone.
