Tombraider 3 on ps2

[ottoman]

Okay. I ask this every so often in the hope that new blood can give me sum kind of answer.

I have tombraider 3 original. This works fine on ps2. I back it up an the backup works fine on my modded ps1 but put it in the ps2 an it won't even look at it. Bombs out after the logo screen. Anyone any ideas.

I know the game works on ps2.

I know the backup is fine as it boots on ps1.
