Bitfold is a retro game console app for iPhone and iPad, made for iPhone Duo. It turns the whole screen into a pocket console — a glossy plastic shell, a pixel-sharp screen, a clicky D-pad, A and B, Start and Select, a power LED and a speaker grille — and it comes with twelve original games. No ads, no accounts, no tracking. MADE FOR IPHONE DUO Closed, it's a classic pocket console on the outer display. Open it and it becomes a Bitfold Duo: the game on the top half, the console's hinge drawn exactly over the real fold, controls and a companion screen below. Fold it like a book and the console opens into two pages. Your game keeps running through every change. TWELVE BITFOLD ORIGINALS Every bundled game is an original made for Bitfold, with its own music and characters: a platformer, a falling-gem puzzle, a vertical shooter, a pseudo-3D racer, a snake game, a block breaker, picture-logic puzzles, a pinball table, a top-down adventure, mini golf, a daily puzzle with a new harbor every day and a virtual pet to hatch and raise. BRING YOUR OWN CARTRIDGES Play backups of the cartridges you own (.gb, .gbc, .sgb, .cgb or .zip) from Files, AirDrop or the Bitfold folder in the Files app. Bitfold doesn't include or download any commercial games. A SCREEN THAT FEELS REAL Sharp pixel scaling, an optional pixel grid, dot-matrix shadows, LCD motion blur, and twelve palettes for monochrome games — from pea-soup green to amber and backlit blue. TWELVE EDITIONS Classic grey, Bubblegum, see-through Atomic purple with a circuit board inside, Lagoon, Dandelion, Berry, Kiwi, Ocean, Midnight, Glacier, Ivory and Champagne, each with a matching Home Screen icon. PLAYS GREAT - Accurate emulation built on the open-source SameBoy core - Four save-state slots, automatic save and resume, battery saves - Hold to rewind, fast-forward up to 8× - Haptic buttons and cartridge rumble - Game controllers and keyboards - Classic cheat codes Bitfold is not affiliated with, endorsed or sponsored by any console maker.
