It's Centipede. Again.
On the Right Controller, hold down one button from every row/column of the keypad and any diagonal direction on the disc (for example, 3 + 4 + 8 + Enter and Southeast), then press Reset. An alternate title screen will appear with a hidden credit for the game's programmer, Mark K. Kennedy. This screen cannot be dismissed with any controller buttons, and requires another reset to return to normal.
There are three hidden messages in the ROM. The first is found at the beginning of the ROM:
Why are you diassembling this code? That isn`t nice!
The second starts at 0x991:
Joe: Knock knock! Moe: Who`s there? Joe: Santa! Moe: Santa who! Joe: Santapede is comin` to town!
The third, a list of credits, is located at 0x3F03:
