Can't convert Utopia "Wacky Races" to Self Boot format

[maverick-uk]

I recentley came across a non self-boot version of Wacky Racers, in the past I have used Echelons tutorial to convert these to self-booting.

I have succesfully achieved this in the past but I can't get Wacky Races to work.

The CD reports as having 700mb of data, yet when I copy all files from it I only get around 430mb, it doesn't have CDDA Audio as far as I am aware.

If I attempt to record this 430mb of Data as a second session on a self boot CD the game appears to start booting, then switches to the DC Menu screen.

Can anybody help?
