if you were still interested in boss rush runs. They way it is currently set up, you can prep your party before hand, going in with whatever weapons, equipment, lvs, etc. The only rulings are that time starts at the start of said rush and that time ends once the rush ends.
These were just meant to be extra little fun categories if people wanted to do them.
The main runs laid out currently are Defeat Smithy (end of 'story mode') and Defeat Xion (the true final boss).
No emulator functions can be used. Play as if you were playing on actual console hardware.
As far as other categories or ideas, I have not really received any suggestions from the community to consider at this time. But thank you for your interest in speedruning this game.
