Wow! Fast reply!
Firstly let me apologise...

I did not mean to imply that cmp scanned incorrectly, I simply meant that many cmp scanned roms (correctly!) show that the crc32s are out, whereas they don't with GoodTools. I worded that horribly and I'm sorry.

Sure. Like I said- I just wanted to use cmp for its wildcard facilities, as I haven't been able to find an affordable external tool that can do this.

Many thanks Roman
