This game has a hidden level select.
Kiwi Kraze is an NES port of the popular Taito arcade game The NewZealand Story, and one of Software Creations' more competently-programmed titles.
In the US or European version, enter the Game Genie code NNNYEYAE (or change ROM address 0x20000 to FF) to enable an in-game level skip. Press Select during gameplay to jump to the next level (or, if you're on level 5-4, the ending scene).
Reset Check String
The game uses the string "HELLOV" (using the game's character mapping, not ASCII!) to determine whether the NES was hard- or soft-reset, and display or skip the copyright screen accordingly. It's possible that the "V" is actually an ASCII space character, a slight error on the programmer's part.
