Um, slight problem....
 

I have the CDI file for DOA2: LE, but it's 713 MB. I assume I need to downsize it. What do I do?

No. Load it into Disc Juggler and stick a 700mb disc in the drive. It will still work (the data is less than the 700mb disc, but the larger .CDI includes overhead data such as the Disc Juggler settings).

Thanks a million. I was getting worried there.

Yes!!! It's works! I didn't even need the boot disk!!!
