Emulation Boktai 1 2 and 3 on supercard dstwo. How do they run?

[Django999]

My three favorite games for GBA, and the sole reason I would even bother getting a supercard dstwo.
I have heard thet 2 and 3 suffer some slowdown. It is gamebreaking, annoying or perfectly tolerable?

Also has anyone played any of the three all the way through who has some feedback on how these games work specifically?

I am also a little curious about steel Empire if anyone knows.
