We made a simple tool for tracking series. It is currently only for NHL94 ROM, and 7 game series. ("We" is Atomic and myself, though Atomic has done the Lion's share for sure. Chaos sent us the gamesave parser to start things off, too.)

This is Alpha, so there will be issues. Atomic and I made it to track our own games, and then thought, hey, let's open it up to the community.
If you have questions about it, ask them here.
