Dark Cloud 2 and Magic v 50k

[guyee]

I have a V9 ps2, and a magic v 50k, i think, i took it to a place and it was installed there.

Now my problem is that whenever I play dark cloud 2, the game doesnt work properly. It boots and all, but whenever i get into battle i can only do 1 damage.

So today i rented the original of dark cloud 2, and played that with the mod chip on, same thing happened. so i turned the chip off and the game plays fine.

Anyone else have this problem? has anyone fixed it, and is there maybe a better chip out for v9 ps2's than the 50k?
