hdadvance and computer

Hi,

I am wondering whether to get hdadvance2.0 and have got a few questions if someone wouldn't mind answering, thanks.

Ok, I know how to back up games onto disc.. got loads of them... so here's my questions:-

1) Can you just hook up a hdd to your computer and then put the images straight from your original/backup discs onto there, and then play them with hdadvance2.0?

2) I'm not sure, but guessing that you run hdadvance the same way that you run swapmagic... but instead of booting another disc you are booting the hdd?

3) The main reason I am thinking of using hdadvance is to play dvd9 discs from there... does this work, or can you only play dvd5 and cd games ?

Thanks for any info on this
