Cracking removes protection to extract existing information. That's the key here.
DarkSpore's assets and some functionality are stored locally, but a major part of it was stored remotely - on EA's servers. Once they shut them down, you can no longer access that data, and therefore cracking it will not help.
You can try to restore it by replicating the server. But since we don't have all of the data, the replication is likely to be inaccurate. That process is called "server emulation", and it really needs a dedicated fan base - not only to get people with the technical know-how, but also because it needs a massive amount of data points to achieve accuracy. DarkSpore, as far as I know, didn't have it when it was still online - and is therefore gone forever (unless EA has a backup/server data somewhere).
