Yes, teams and romhacks are allowed. Keep in mind that you can only upload the patch and can't tell people where or how to obtain a rom though. Graphical hacks are fine as well, but keep in mind that you'll have to win over voters to get the win. You can participate however you like though!
Keep in mind, to keep in spirit with a game jam, you don't actually start on the project until the 26th. You can gather your resources, gather team members and plan though.
