Help in KH 358/2

There a big problem that's bugging me: I can't damage the Veil Lizard at all...its in the Search for Xion mission

You have any magics or good keyblades? Or it could be that the game is glitching out, just either restart the system or the mission itself.

I'm playing on No$GBA 2.6a, can that be the problem?

possibly, i play it on EDGE for my ds itself, some emulators for the pc don't work as well as flashcards in my opinion at least

Problem Solved, it was my 1-hit kill AC that was buggin'

Ah, Gotcha. lol
