Getting past anti-mod protection using gameshark code help needed.
 

The situation:

I need to use a gameshark code (which is listed on megagames.com) to bypass the anti-mod protection on the Japanese import game, Yu-Gi-Oh! Shin Duel Monsters which was made in 1999. I am looking for a way besides modding my playstation.

I am trying to play the game on the American version of PSOne so disk swapping is possible.

I am willing to make a purchase if it is nearly guarunteed to work and will consistently boot up the game properly (saving me precious time). If it is cheap enough, i would prefer a solution that saves me the most time (i.e. not having to attempt disk swapping for a half an hour just to boot up the game).

Thanks in advance for those who take the time to read my post.

I went ahead and ordered a PS-X-Change 2 disk (~$20 S/H) and it works with this game. You need a hot swap-able Playstation and use the code you find on megagames for Yu-Gi-Oh Shin Duel Monsters.
