King Kong 2

A Japanese game, based on the American film King Kong Lives, which was only released in Japan. Funny how these things work.

CRC Test
Press and hold A + B on the first controller, then press Reset. After a while a message will appear. "KINGKONG" string stands for PRG ROM checking, "KONAMI" string stands for CHR ROM checking. "ONE" means test OK, "TEN" means test fails.

Easter Egg
After beating the game, when THE "STAFF" roll is about to end, before the messages "PRESS START BUTTON" and "PLAY TIME" appear, press and hold A + B. Another message appears, depending on how many hours in total you've played. There are 24 messages in all. The meaning of numbers at the end of almost every string is unknown.

Level Select
Press Right, Left, Right, Left, B, A, Up, Down, Up, Down at the title screen and then press any other button before pressing Start. During the game you can press the A button on the second controller to switch level or the B button to hold a game.

Unused strings
There is some unused text strings previously used for some menus or messages. First one is a missing STAFF person name, that doesn't appears in the final STAFF roll: "SHIMONETA KENJI".

Second ones, is a presumably strings from the old version of the title screen: "PLAY SELECT", "KONAMI 1986", "PUSH START BUTTAN".

Thrid ones, totally removed password screen texts: "KEY WORD", "END...PUSH A BUTTAN", "KEY WORD ERROR".

And finally, at the beginning of the RESET routine, a version string placeholder appears: "RCxxx 1.0 .date.".
