Here's a quick conversion of the two-subleague schedule that comes with the game. It's modified for the actual set-up of the NA in 1871 - i.e. a single nine-team league. I haven't made any other changes to the schedule. Anyone using this schedule should change the default settings in the Options menu to a 32-game schedule and no interleague.
