Somethin interesting about SC2 3DO iso...
« on: February 18, 2006, 10:30:38 am »

I was just screwin around and decided to hex edit my SC2 3DO cd iso and there is a phrase "i am a duck" that is repeated multiple times in the 'beginning' of the iso file.

don't know what it really means, but a few of my other 3DO iso's have it too, so it just doesnt pertain to SC2.

It's not just in the beginning, it's everywhere in the ISO. The phrase "iamaduck" (no spaces, 8 bytes) seems to repeat at the end of each file (possibly losing the start so that it always starts on a multiple of 8 bytes) until the next multiple of 2 KB is reached. It looks like the Opera file system is using the phrase as padding.

Not really. If your file system is based on fixed-sized blocks (like most file systems), you'll have wasted space at the end of each file. Using an instantly recognisable string is a nice debugging aid when you're trying to debug the file system.
