Wonderful! I wish I could play Nintendo Game Cube games tho

I’ve been looking for a gaming app where I can play all types of retro games on my iPhone and I FINALLY found the perfect one ❤️ however, I wish I can play NGC games on the app. I’ve been trying my best to make it work and no luck, so hopefully the developers can make an update. Also, I love that this app if free and has no ads 💕💕💕 it’s a win for me! 🤠

So good! But…

I love delta. My friend helped me emulate some games on here that I’ve been dying to play ever since my old DS broke. It helps keep the nostalgia alive!! One issue however is this; I want to screen share with my friends on call so we can all play together and have a good time, however the audio disappears but you are on a phone call. I want this to be fixed. This is because music is one of the most important factors in all of video games and to able to hear these songs I used to love to much with my new friends would literally mean the world to me. Please, fix this delta!! T_T
