island,
You can't do any better than Microstudio. It's the least expensive method for importing the multisession cdg's and besides, the software is great.
There was another post here on this forum that suggested using cdwin and cdripper in combination to do the same job, don't bother. It's more expensive and more involved than using Microstudio. Take it from someone who knows. Like the commercial says "Just Do It".
