Earlier, the article mentioned Delta as the best Nintendo emulator for iPhones. But to unlock the Nintendo DS emulator on Delta, you need to pay for a Patreon subscription. That is where iNDS develops its strength. This emulator allows you to play Nintendo DS games on iPhone for free.
iNDSOriginating from the popular NDS4iOS emulator, iNDS is available for non-jailbroken devices via iEmulators and BuildStore. As with all iOS emulators, Apple sometimes revokes licenses for this app (which means you may have to wait for developers to renew before you can install it on an iPhone).
But once it works, iNDS will allow you to play Nintendo DS games at almost maximum speeds on iPhone 5 and above and up to 60FPS on newer iPhones.
Take advantage of the saved state and the option to automatically save to sync game data via Dropbox. You will never have to worry about losing process, even if the emulator is revoked. iNDS also includes 100,000 cheat games to add interest to your favorite DS games.
Because the Nintendo DS has two screens, you can use iNDS in portrait or landscape mode with both screens appearing in the middle of the iPhone screen. You can also customize the size and style of the handle, and even disable the touch screen on the second screen to avoid accidental errors.

PPSSPP is dedicated to emulate PlayStation Portable games (PSP) on iPhone, iPad or iPod touch. Although PPSSPP can run any PSP game on the device, older iPhones may not be able to run games at full speed.
PPSSPPLike all other emulators on this list, you can create a save state for your games. You can also add cheats to the game for added fun.
Perhaps one of the best features of PPSSPP is that it gives you the ability to transfer existing backups from a real PSP.
Unfortunately, PPSSPP doesn't seem to have an integrated way to sync your games to the cloud. However, this may be the best option considering the fact that most PSP ROMs are extremely large files.
