The screenshots are from the MSX2 version. There are two versions, both with SCC sound and maybe the same stages (I only have concluded the MSX1 version). I think the only important difference is the graphics.
The game is wonderful, amazing, an astonishing piece of code, graphics and sound.
In the MSX2 version there is some odd freezing when you thraw some weapons like knifes etc... The MSX1 version run totaly smoother on this point, which makes it a little less stranger to play.
