(BURIED) Hidden text:
RESET routine in this game uses string "D.BUSTER" to check if game was soft or hard reset. Also game contain some hidden copyright text at end of file: "HARUHISA.UDAGAWA & KUMI.HANAOKA". This text is a part of hidden CRC test routine and used in some other games programmed by the same people, but in this game this sting doesn't used as test data.
XTUYNTES+XTUNEVTU - At reset game performs some manipulations with expansion port sending and reading some data sequence to it then compare resulting data with original. Probably there is some special device for testing purposes only. With this code you may pass device checking and see CRC test itself. If data matches, game performs partial (one from each 15 bytes) data CRC tests. While checking PRG data display color is red and if check fails display will remain red and game stops. While checking CHR data display color is green and i check fails display will be flashing from red to green infinitely. GoodNES version ROM pass this check normally.
