Yes, the Korean Master System conversion of an MSX rip-off of a fairly well-known little platform game from Japan.

Just stage 1-1 for now, I don't know if I can bear to play much more of it.
Am I correct in assuming that "Boy II" is Korean for "Mario Brothers"?

Dot? Dot. Dot!
Those graphics really don't do justice to the SMS. I guess they just ported the code and said "screw it" when it came to the graphics.
Being a port from the MSX, it uses the SMS's SG-1000 compatibility video mode, which is the same as a Colecovision (ie. pretty lame).
