Hey,
Astarte was good for psx games in OS9, but there are no new versions.
if you have Toast, you have all you need.
Click the "Copy" tab in the Toast main window, and choose "CD/DVD copy" from the menu on the side of the window. Now the window should display info on the disc you have inserted in your Mac.
Now, go to the "File" pulldown menu on the top, and choose "Save as disc image". Choose where to save the file, and when it's finished, insert a blank disc, choose "image file" (right beneath "CD/DVD copy"), and drag the image file into Toast.
And burn.
Ta-daaah!
