Seems like JIT bug
False. I just got 2785 and it has the Francis' private room bug as well.other versions do not allow to enter into Francis secret rom to get the Fort key, so you must use cheat code.. but using cheat codes i got this bug
for Super Paper Mario version 2785 is the best , i think that you can even buy items and spend coins try it (currently i am ate level 4-3)
