No, not the code.. I diff'd the code line by line against other coins already and found all the deltas.  All the bad code has been removed and reverted with the fixed client.

However I didn't look through all the blockchain, I relied on block explorers to look at the key places in the blockchain that relates to the premine... of course there are thousands other transactions that I didn't look at.. I just traced the premine from the original block, and looked at all blocks where it traversed to.
