If you’re an iPhone user, there’s no doubt that you’ve heard of Delta in the emulation scene. But for those looking to keep up, Delta has been one of the biggest Nintendo emulators available on the App Store for a while now, but with their 2.0 update dropping, it’s looking to be even more. From controller and design updates to RetroAchievement and iPhone Duo support, it’s obvious they’re cooking pretty hard, and likely won’t be stopping any time soon.

If you’re looking to check out Delta, you can find it both on the AltStore or over on the App Store. And if you want more information you can be sure to check out their Bluesky account where announcements like the 2.0 Drop were shared as well.
