Anti-mod chip code problems "Legend of Dragoon"

[Viguro]

I might be a moron to even have this problem but here go's nothing:

I have something called "Boot Disc Ver.2" but I don't think its any different from a psx-change 2. I burned "The legend of Dragoon"with Greatest Hits band on it, I burned many games in the past before, I use Easy CD Creater 5 and all CD's I burned in the past work perfectly, but Legend of Dragoon doesn't work, even WITH the anti-mod chip codes...... I use a psONE unmodded, I tried the codes in all the ways I think work, and so far no luck. Is there something I'm doing wrong? Pleas help me!
