Flycast

Overview

Flycast emulates Sega Dreamcast, Naomi, Naomi 2, and Atomiswave; its Android listing also names System SP arcade games. It says most Dreamcast games run, including Windows CE titles, which makes Flycast a strong fit for varied Sega collections without promising compatibility for every title.

Game files are not included and must be owned by the user. A Dreamcast BIOS is not required, removing one setup dependency. Controller support and online multiplayer are supported, alongside modem and LAN adapter emulation and RetroAchievements. The Android update notes also name Power Smash online support, a useful addition for players interested in that title's online play.

Key features

Graphics and save states

On Android, Flycast supports OpenGL and Vulkan, high-definition and widescreen rendering, and custom high-definition texture packs. These options offer ways to improve presentation, but they are not a guarantee of uniform results across games. Android users also get 10 save-state slots, providing room to preserve multiple points in progress without relying solely on in-game saves.

Build choices

The project provides versioned stable releases, regular master builds, and experimental nightly development builds. Master is described as relatively stable; other branches may be unstable, crash, or refuse to run. Players who value reliability should favor a stable release or master rather than treating a nightly as a routine upgrade.

Pricing

Flycast costs 0.00 USD per free. The free plan has no ads and includes the emulator, but not game files; users must own those themselves. There is no paid tier to unlock the listed systems or features, so the trade-off is the user's responsibility for obtaining games and choosing a suitable build.

Platforms

Flycast supports Android, Linux, macOS, and Windows. Builds for Xbox One and Series can be installed using Xbox Device Portal, but iOS support has been dropped. That makes Flycast a desktop-and-Android option rather than a current choice for iPhone or iPad users.

Who it's for

Flycast suits players who want one emulator for Dreamcast and Sega arcade systems, especially those who value HD and widescreen options, save states, or online-related features. Its multiple build channels suit users willing to select between stability and development builds. It is a weaker fit for anyone expecting bundled games, iOS support, or assured stability from experimental branches.

Pros and cons

• Pros: Emulates Dreamcast, Naomi, Naomi 2, and Atomiswave, with System SP also named in the Android listing; useful breadth for Sega libraries.
• Pros: Android offers HD and widescreen rendering, two graphics APIs, custom texture packs, and 10 save-state slots.
• Pros: No-cost use, no ads, controller support, online multiplayer, and no Dreamcast BIOS requirement reduce cost and setup friction.
• Cons: Game files are not supplied and must be owned by the user.
• Cons: Non-master branches may be unstable, crash, or fail to run; choosing a build requires care.
• Cons: iOS support has been dropped, excluding current Apple mobile use.

Alternatives

Browse Dreamcast Emulators for a category-wide comparison. MAME is another free option for Android, Linux, macOS, and Windows, with a GPL-2.0-or-later license; its ROMs and copyrighted software are generally not included. Choose it when that option better fits your needs.

WashingtonDC is free and open-source under GPL version 3, but its listed platforms are Linux and Windows. Deecy is another free option for Linux and Windows. nullDC 2.0.0 is free and lists Linux, macOS, web, and Windows support.

Redream is a freemium alternative for Android, Linux, macOS, and Windows. Its Premium plan is 6.00 USD per once, with pay-what-you-want amounts of $6, $8, $10, or $20 and high-definition rendering among its listed benefits; consider it if that payment model suits you better. Nitrocast is a free alternative for Linux.

Verdict

Choose Flycast if you want a free, multi-system Sega emulator with Android graphics options, save states, and online-related features, and are prepared to supply your own game files. Its system coverage is the main reason to pick it; look elsewhere if you need iOS support or want to avoid build-stability uncertainty.
