Jackie Chan's Action Kung Fu (NES)

A pretty decent NES port of the TurboGrafx-16 game of the same name.

Level Select
On the title screen, press Up, Up, Down, Down, Up, Down, B, A, Start. To get 99 continues, press B on Controller 2 after entering the code.

The level select code lets you start at any of the five areas by pressing Up or Down. This code is mentioned in the manual as a secret code for 99 continues, but fails to mention the level select bit.

Regional Differences
The European title screen is identical to the US one, aside from the copyright being updated to 1991 and the licensing now saying "LICENSED BY NINTENDO". The Japanese title screen omits the licensing completely, and features the Jackie Chan sprite from the game.
