Hey, I’ve been following iOS emulation for a while, and I can say Delta is definitely the most polished and widely recognized option out there right now. Delta is the first major emulator approved on the App Store after Apple’s policy relaxed, focusing on Nintendo consoles up to N64, and it’s already teasing some neat new features. That said, Delta isn’t the only viable emulator for iOS anymore—there have been brief appearances of apps like iGBA, and there’s talk about PPSSPP (for PSP) making a comeback.
But when it comes to consoles beyond Nintendo—like PS2, GameCube, or Xbox—these are much trickier due to Apple’s restrictions and the performance requirements. Those emulators aren’t likely to hit the App Store soon, but you can still explore side-loading options like AltStore if you’re comfortable with that. Also, for developers or testers working on emulator interfaces or performance across iOS devices, tools like LambdaTest provide real-device cloud testing to ensure compatibility with iOS web wrappers or companion apps. It’s a handy way to check emulator UI responsiveness without juggling physical hardware.
