Your DVD-drive can't read the GC disc, so I can't imagine how you succeeded to make an image. You do seem to get to the start of the intro. I have the original.
Why don't you just admit you have downloaded it? No problems here, as long as you don't share where you have downloaded it.
If you own Phantasy Star Online Episode I & II, a GC Broadband and a cross-cable, you can fool the GC and rip the GC-disc to your PC. I'm sorry, I don't know how you do this exactly. I'm still looking for a cheap PSO to do it.
