Pretty much what the title says.

Even though it's a near carbon copy of "Instant Replay" with relatively few changes in dialogue, Emi's bad ending is inaccessible from the library and there's no empty slot indicating its absence, so this might mess up the efforts of people going for 100% completion.

The library only contains one version of any given scene.
Since the flag for Emi's bad ending has been set in a previous scene (when you talk to Misha) there is no way to make the other version play from the library. You have to reload a save.
If you have unlocked the scene it does count towards the 100%, though, even if you haven't seen both versions.
To unlock the bonus CG you have to have seen the ending credits from the bad End, so if you haven't unlocked that, you have to reload.
