Well first off; congratulations on buying such a great program.
Now download Betablocker 2.51 - try
here .
What you need to do to copy this game with your Plex 24 is this:
1) Read the image file at no more than 4X. Read from the Plex, with Fast Error Skip checked
2) Patch the image with Betablocker 2.51
3) Burn back to CD-R(W) at no more than 6X. You can tick Burn-proof, and always close last session. DON'T tick AWS.
4) To play from the Plex, enable Hide CD-R Media in the Clone CD Tray as the game also has an ATIP check. If you are playing from a normal CD-ROM there is no need for Hide CD-R Media.
This works for me as I have a Plex 24
BTW: Do you same for both disks.
