Labyrinth

(BUR) GameGenie (added 04.12.13):
TONTSSGP+YENVKIIO+IAETVVLA+AZEVKVGG+YYEVSTZO-Re-enables level select cheat. This cheat were probably intended to be called on pause or during the game with some buttons held, but currently there is no proper button reading on pause, so with some hacking it was returned to ingame mode. During the game press A to increase internal level counter, press B to advance to this level. Most interesting, that cheat should be much harder to enter, while holding B you must've enter at least Down, Left, Down, Right, Down, Up, Down, Up, Left, Down, Right, Up, Right, Down, Left, but the first button code was replaced with $FF (but probably it was Down), and cheat were shorted just to B.

Copyright 1987  Namco Ltd.  All Rights Reserved Programmed By.. HARUHISA.UDAGAWA &  KUMI.HANAOKA
The names part of this text used as part of data for a hidden CRC test routine.

(BUR) GameGenie (added 26.06.14):

GAXYNTEI-There are a series of the Namco games, made by the same programmers Haruhisa Udagawa and Kumi Hanaoka, that contains the same self-test for the data integrity. To enable any of these tests you need a special device that should be plugged into the expansion port. The operation of that device is very simple. It should accept the data bit from the data input port and return it back inverted to the output data port. The device consists of 4-bit shift register, working as some sort of the FIFO buffer. The input bits are goes to the input and then shifted to te output after a 4 cycles. At the game's boot, it tries to send some special data to the device. If the data output doesn't match the data input inverted, then the game continues the normal operation. But if all data (usually 32, rarely 64 bytes) is matches, self-tests will be performed. The program calculates 24-bit partial checksums for the PRG (excluding the last 8K) and the CHR data, summing only every 15th byte, and comparing it against the etalon. Before testing of the PRG data, the background color turns red, before testing of the CHR data, it turns green. If any of these tests are failed, the program will jump directly to the reset routine. It means, one of these tests will be performed infinitely, but until the special device is plugged in, or until the test are passed. Normally, you'll see the red to green flash just before the game's boot. Or the static red screen if the PRG data is bad, or the flashing red to green screen if CHR data isn't good. Using this Game Genie code you can skip tests for the special device presence and jump straight to the integrity tests.
