Dragon Ball Z Idainaru Son Goku Densetsu help!

Hey everybody!!

I'm having a hard time playing Dragon Ball Z Idainaru Son Goku Densetsu (Pc Engine CD). The game is way too difficult. :(

Is there an invincibility or unlimited ki code in the game? If so, how do I access it? Can you guys give me some hints/tips?

Thanks!!!!!!!!! :)

OOPS sorry for posting in wrong area

Its in an okay forum.

So any cheat codes/tips??
