Delta has years of polish behind it.

Caveat: It isn’t available in the app store in the EU, and is instead only available via the developer’s marketplace, AltStore¹. As far as I can tell, this genuinely isn’t because of greed, but because of a little detail in Apple’s EU rules (possibly wrong):

[…] Developers can choose to remain on the App Store’s current business terms or adopt the new business terms for iOS apps in the EU.

Developers operating under the new business terms for EU apps will have the option to distribute their iOS apps in the EU via the App Store, Web Distribution, and/or alternative app marketplaces. […] Developers who achieve exceptional scale on iOS, with apps that have over one million first annual installs in the past 12 months in the EU, will pay a Core Technology Fee. ²

The problem being, if you’re under the old terms, there is no “Core Technology Fee.” However, in order to distribute on another marketplace, you must opt into the new terms, meaning you now have to pay the fee even on apps that are distributed on Apple’s app store. Thus, if you distribute on the iOS app store in the EU for free, and lets say it gets 2 million installs, you get 1 million installs free… and you now owe Apple half a million dollars.

    The app marks the first significant and officially sanctioned game emulator for the iPhone since Apple began allowing them, with wide-ranging console emulation from the original Nintendo Entertainment System to the Nintendo 64 (and even the Sega Genesis, for when you want to play those games that Nintendon’t).

    Delta developer Riley Testut told The Verge via email that the app is identical to the version debuting with AltStore PAL.

    The app features on-screen buttons that change their layout and appearance to match whatever system you’re emulating.

    It supports Bluetooth controllers like Xbox One Series S or PS5 controllers, too, and the app lets you customize their layout or set extra buttons for things like quick save states (essentially letting you pause a game whenever you want and load it up from that point later) or fast-forward through an old-school game’s all-too-often unskippable cutscenes or endless stream of startup logos.

    Both were short-lived, though, with Apple taking down iGBA over spam and copyright App Store rule violations and Bimmy’s developer getting cold feet in light of Nintendo’s recent crackdown on emulators.

    That means the app has already been through five years of feature and bug-fixing iterations, so it will likely be one of the most polished emulation experiences on the iPhone for a while.
