Update 2.4 has fundamentally changed the way Story Mode will work in a few key ways, so there are now two subcategories for Story Mode: Pre 2.4 and 2.4+. The ways it has changed include:

• Sinbad's automatic shield break with ftilt has been removed, making the fast kill against Kiki impossible in 2.4 onward.

• Sinbad's upb now doesn't kill as easily off the side.

• Difficulty drops if you lose a stock, which may have some mild implications for purposefully losing to save time (though it likely wouldn't save enough to matter).

Update 2.4 may affect Story Mode in ways we can't yet see, but these are all ways in which it definitely does. As all versions can be emulated and you aren't forced to update your cartridge, I will keep pre 2.4 up to continue to be ran (I myself will likely run it; sub 50 might not be possible in 2.4).
