Problems with an original Legend Of Dragoon NTSC game on a modded ps2

[Shadow_Zero]

well, first of all i'd like to introduce myself. i'm Shadow Zero, hi! um, well, i bought the original Legend Of Dragoon Game (ALL Disc's) and i wanted to play it on my modded ps2. so i put in disc1 of Legend Of Dragoon. i waited for the game to load and it worked the PlayStation Logo came out and all that, and then the game started...but when it started a message poped out with this warning sing on the back. saying something like this "Your Console has been altered. Please call (i don't remeber the number)" so i can't play the game. but i found out on the internet that there was a GameShark code that could bypass the anti modchip thing on The Legend Of Dragoon. so i got GameShark Lite and put in the code i found in the internet but nothing happend the message of legend of dragoon poped anyways. So i'd like someone to give me the code cuz maybe i'm using the wrong one.

this is the code i've been using:
D01BF664 FF52
801BF66E 1000

and some others too

please someone help me so i can play this game
thankyou for your attention.
