I think this is the reason the client is eternally stuck in "not done yet" mode... looks like the dev forgot to delete checkpoints from the source he copied! Or can see into the future.

Does this mean the clients are going to start dropping off when we hit block 1500, and the hash doesn't match the checkpoint?
Nice work. I think the only person mining this coin on block 1500 will be nintencoin, so no worries that it gets stuck!
