Plume is a Dreamcast emulator built for iPhone. A polished library, many graphics options, and controls for both handheld and couch coop! Add titles through the Files app, AirDrop, or Share → Plume. Supported formats include GDI, CDI, CHD, CUE, BIN, ZIP, and ELF. A small homebrew demo ships with the app so you can try the core on first launch. Retail BIOS files are optional — turn on Fast Boot to skip the splash, or add dc_boot.bin and dc_flash.bin from hardware you own for the full boot sequence. LIBRARY Your collection lives in one place with cover art, metadata, favorites, and played time. After you run a title, Plume grades how it performs on your phone — Excellent, Good, Playable, and more — so you know what to expect before you boot. CONTROLS Use fully customizable on-screen controls, or pair a Bluetooth gamepad in iOS Settings and remap every button in Plume. Dreamcast has four controller ports. Touch controls fill port 1 when nothing else is connected. Rumble, haptics, and light-gun support are built in. CONSOLE MODE Mirror your phone to a TV over AirPlay or HDMI. In Console mode the game renders on the big screen while your iPhone stays the controller — perfect for couch sessions. GRAPHICS & PERFORMANCE Tune internal resolution, aspect ratio, CRT shaders, texture filtering, and upscaling. MetalFX spatial and temporal upscale is available on supported Apple silicon. HD texture packs, neural upscale models, and an Upscale Studio help older titles look sharper. A live HUD shows FPS, frame time, CPU, RAM, and more. SAVE STATES & VMU Save and load states from the in-game menu. Slots appear on library covers for quick resume. Per-game VMU files keep memory cards where they belong. RETROACHIEVEMENTS Sign in to RetroAchievements and earn badges while you play. Hardcore mode disables save states for a classic challenge. CAPTURE & SHARE Take screenshots and record gameplay in-game. Saves go to Documents or Photos. Attach captures to save-state slots if you want a visual bookmark. SOUND & STYLE Menu music with downloadable tracks or your own imports. Deep theme controls for colors, fonts, corners, and accessibility — including Bold Text and Button Shapes when iOS has them on. REQUIREMENTS Plume is iPhone only. Requires iOS 18 and iPhone 13 or newer. Dreamcast emulation is demanding — your device may warm up during play, and heavy 3D titles may not hit full speed on every phone. Plume uses a cached SH4 interpreter (no JIT), so performance depends on your CPU. SUPPORT & SOURCE Questions, bug reports, and betas: join our Discord from Settings → About.
