Cubivore won't run but other games will?

[jbblossom]

Hello forum, thanks in advance for replies. I recently got "New" computer, from a thrift store, I'm in a low budget lol. Either way after swapping some parts between it and my old computer it looked like it was up to the task of emulating. Now I have dolphin set up (the basic set up it is installed with) and I got luigis mansion playing, however I can't get cubivore this play. I do own the disk but it has become to scratched to be functional over the years, so I downloaded the iso from emu paradise. The iso is about 93.9 mb which doesn't sound right to me, and what I think is the problem honestly (also I had to unzip the folder, and then unzip another folder from the previously extracted folder to get to the actual iso?) Any suggestions? Is that the not full iso or should I change done settings?
