Here is a hack of the game a little-known Korean firm "Open Corporation".
* Sprites of the hero (Metal Force) were converted to the well-known "Megaman X" from SNES (thanks @ArcherNorinton for that).
* Lives now is 4. The palette of the game has also been partially changed. The final word in the cutscene were changed.
P. S.: Enjoy it!
