I apologize, i thought my question was fairly straightforward.
I don't know how you're calculating the total CRC-32. my attempts at using various calculators to take 2 or more CRC values out of the dat/webpage result and sum them up doesn't result in the value you have as total CRC.
I'm not interested in reinventing the wheel here. i need a solution that allows me to check the site pretty much any time and see if there are changes or updates to any disc (not just saturn mind you) and if there is a change against what was last checked/calculated, obtain the total CRC again and verify it against the dumps i currently have for that title.
I'd MUCH prefer some semi static listing of Total CRC, either in the database or in the dat, but upon opening the dat, i saw the value wasn't listed there either. I don't want to factor in your on the fly calculation into my programs/scripts as doing that will add an extra potential point of failure. If you won't incorporate Total CRC as a static stat into either the dat or the webpages, i've got not choice but to do that on my own, but i still would rather be handed the code/algorithm than try to "figure it out".
And yes, the data base dump would also be super awesome since a lot of the requested data isn't in the dat file anyway.
