Homebrew Help With Pokemon HeartGold

[CatastrophicSuic]

So I Was About To Play Pokemon HeartGold On The No$Gba 2.6a. I however ran into a strange glitch in my battles.
I don't know if it is related to my graphics card or anything. So please help me? P.S- I own the game, but don't have a ds anymore
