Thanks for letting me know about this. Oddly enough, both trainers have a Premier Ball in their inventory. I have no idea how this happened, as they didn't before, and I haven't touched the trainers data in months. I'm gonna scan through and see if I find anything else out of the ordinary, and will fix this in an update.
As for you guys with the DSTwo problems... that's an emulation failure problem and can't be fixed on my side.
