About This Release: Delta v1.0 was the first public release of Riley Testut's successor to GBA4iOS. It launched with GBA-only support but with a clear roadmap to expand to other Nintendo systems. The response from the community was immediate and overwhelmingly positive - Delta filled the gap left when Apple cracked down on GBA4iOS-style apps, giving iPhone users a legitimate, stable, non-jailbreak GBA emulator for the first time since GBA4iOS was shut out of the ecosystem.

Minimum iOS: iOS 12.0
