Emuki puts thirteen classic consoles in one pocket. It is an emulator written entirely from scratch — every CPU, graphics chip, and sound chip implemented instruction by instruction, with no third-party cores. That means steadier frame rates, lower battery drain, and controls that actually feel responsive on iPhone. ■ Supported systems • Game Boy Advance • Game Boy / Game Boy Color • NES / Famicom • Super NES • PC Engine • Master System / Game Gear • Genesis / Mega Drive • SG-1000 • ZX Spectrum • Neo Geo Pocket • Atari Lynx • Virtual Boy • WonderSwan / WonderSwan Color ■ Built for comfort • Save states — save anywhere, resume exactly • Timeline rewind — hold to roll back a few seconds; a mistake no longer costs a run • Fast-forward — skip grinding and long cutscenes • Display filters — crisp pixels, scanlines, or smooth interpolation • Adjustable touch layout — move and resize buttons; landscape re-flows automatically • Bluetooth controllers — MFi, Xbox, and PlayStation pads work out of the box • Local two-player — a second pad on supported systems ■ Your saves stay safe • Export both battery saves and save states • iCloud sync (membership) — switch devices and your progress follows • Auto-resume — a snapshot is kept on exit, so reopening drops you right back in ■ And more • Cheat codes (membership) • Custom touch skins, including Delta skin import (membership) • RetroAchievements (Max) • On-screen text translation (Max) — recognise text on screen and translate it in place • Play-time statistics • Home Screen widget and Siri Shortcuts • Full iPad layout • Interface in thirteen languages ■ About game files Emuki ships with no games and distributes none. The installer contains no commercial game data, and the app offers no downloads, search, or links. You supply your own: dump backups from cartridges you legally own using a cartridge reader, or use homebrew released for free by its authors. To import: open the Games tab, tap + in the top right, and pick a file from Files. ■ Membership The free tier plays Game Boy Advance with every core convenience included — save states, rewind, fast-forward, filters, controllers, local two-player — and shows an interstitial ad when switching pages. Pro: ad-free, cheat codes, skins, and iCloud sync; unlocks GBA / GB / NES. Max: everything in Pro, plus all 13 systems, achievements, and on-screen translation. Subscriptions renew automatically and can be cancelled any time in system settings.
