Can't Open My G1 Raw files

Hi All,
I shoot with a 20D now, but my brother is using the old g1 and accidently shot in RAW mode and the image browser I'm using with my 20D won't open them. It says the file utility isn't installed. I can't remember what to do to solve this. I don't know where the install disks even are for this camera anymore. HELP! His kid's halloween pix are 'locked' up and begging to be emailed across the country for family and friends.
Thanks
Richard

Using a utility as Adobe Digital Negative Converter you can convert them to DNG files, but I’m afraid that zoombrowser will not handle DNG files either, so you will need a DNG compliant software to ‘develop’ them into jpg files.
Save your original RAW files, if you find an older zoombrowser’s RAW task, it will handle them better.

Everything is ok now.

I opened the files in Lightroom and then exported over to Photoshop CS.
