Wip3out with SE circuits (epsxe)

Hi guys,
i´m trying to modify the iso of Wip3out to replace the circuits, and put the remakes of W3 SE. This will give us other Wip3out with the fisics of it (not the modified in SE), and Eliminator in single player.
The problem is, when i try to load the modfied iso in epsxe (psx emu for pc), this never load. Someone can help me?
I think it could be interesting to create this iso and also add the music of wp1 and 2, to play those circuits.
Thx.

Here's a friendly warning: don't talk about modding Iso's here.
