That's fair, though for what it's worth, out of everything I've ever tried to do to get game controllers working nicely on a PC (and I ran the gambit from the last generation), the SCP wrapper is the most straight-forward and seamless thing I've ever found. I haven't come across a single issue in any game, or emulator, I've used it with. Granted, I can't speak to its support for the DS4, not owning one, but it works perfectly in every way with my DS3, even after the move to Windows 10.
Not trying to convince you otherwise, but offering a testimony.
Haven't gotten far enough to get any attack-all spells, but I have noticed the odd SFX cuts, like with the field notification points, so it wouldn't surprise me that that's another bug.
You know, on the topic of bugs, that list of bugs is oddly reminiscent of the original PC port, and seems similar to the PS2 ones, as well. I wonder if there's something common to the porting process that keeps cropping up with this game that just works right on the DC.
