We talked on the GBDev server about this emulator and the gbatemp thread and @endrift just straight up confirmed the suspicions mentioned in the gbatemp thread. It's literally GBA4iOS. The developer likely just modified it to add ads, trackers and the GBDev link.
So Apple users, don't download this. Wait for better emulators to come out.
