Ok guys, here's the story. I ripped the original image from the original disk of Fifa 07 (PAL). I burned it onto a disk, and found out it wouldn't get past the loading screen.
I then burned Zoneloader, loaded up Fifa 07 using that after Swap Magic, and got the same problem. I then rebuilt the game, burned that (4x Verbitam DVD-R) and tried it with both Swap Magic and Swap Magic>Zoneloader. The game loads up into the match, but I receive many problems such as,
* Long pauses in the gameplay
* Sounds/Commentary freezing
* Loud noise as PS2 attempts to read disk.
I couldn't rebuild the game using the gnie tool, so I had to do it using CD/DVD Gen and ISO Buster. The final image was 2.49Gb and it works fine on my PS2, which has a Messiah chip.
Don't know if that's the size you got?
If it's different then maybe's that's the problem
