I had tried 3 games on gamecube like Batman vengeance, batman rise of sin tzu and teen titans. Batman is working almost perfectly, but it kinda lags on challenge mode wish it will be optimized as well. Batman Vengeance is not playable after you chose a memory card to save or without saving the game, when I entered the game it only shows blackscreen and I tried the newest build it doesn't work. Secondly, the Teen Titans game. The arena mode works and it is playable but when you get to story mode after finishing the tutorial, the emulator crashes, please fix the Teen titans game 
Thank you so much
