Okay, not sure this belongs in this forum, but hopefully someone can help me out.
I've been downloading some homebrew games for the Dreamcast. I really liked the Beat of Rage Collection 1 so I thought I'd try Beats of Rage Collection 2. The site (can't remember it now) said the image is 700MB. Cool, just just fit on my CDR. Problem is Alcohol, and Windows XP for that matter, is reporting it as 774MB so I can't get it burned.

Is there a way to edit the CDI file to remove some information so that I can burn it??
I tried mounting the drive, but Windows XP claims it's an invalid format (or something like that). So, I have no idea how to work with this. Any help would be greatly appreciated.

Thanks.
