I told you I'd take a look at it later. Patience is a virtue.
Anyway, there's a reason the ISO doesn't work. It's hosed. Some fool went to town on it with PowerISO and managed to alter a lot of relevant data. You could (optimistically) hack it back in if you've got spare time to pour down the drain, curiosity, and a masochistic streak. But I wouldn't recommend it unless you're determined to learn.
It's kind of not worth your time, so just go buy a copy of it and rip it yourself. It's definitely got a low ROI in my book. The most you'd get is data approaching a usable state, when you could spend $5 (well within most budgets) and get it over and done with. You've got to be a
real hardcore penny-pincher to ignore that.
But it was interesting to poke around the desecrated corpse of the game and lament the fall of data integrity. We hardly knew ye.
