It's based on the version included in Dracula X Chronicles in every aspect at least from what I can get here and from friends who has the Requiem version - but according to Romscout's demonstration it seems like you can chain another bat form's wing smash after performing one which is one of the more in-depth stuff adjusted & adapted in PS1 English versions/Japanese PS1 re-release/XBLA version and I believe in DXC version for some reason you can't do that.
What I'm in a special grief is the slash effect of some two handed Katanas still goes like this thing in DXC version
The slash effect in the original PS1 version
Compared to what I can get from videos/friends about Requiem version and what I can get from original/DXC I don't think there're other "2018 specifics" if any.
