Flycast review
A broad, free emulator for Dreamcast and four related arcade platforms.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Flycast is a free, open-source emulator from Flyinghead for Sega Dreamcast, Naomi, Naomi 2, Atomiswave, and System SP software. It is intended for users who want one application covering Dreamcast and several related arcade platforms, with standalone builds for Windows, macOS, Linux, and Android. The published feature set includes gamepad and force-feedback support, save states with multiple slots, modem and LAN adapter emulation, high-definition and widescreen rendering, custom high-definition texture packs, RetroAchievements, and networked arcade and Dreamcast features.
Pricing is straightforward: Flycast is free, with no paid plans or feature tiers described. That gives users access to the emulator's listed platform support and capabilities without a subscription. The project is open source, and the published category specifications identify controller support, save states, and online multiplayer. Flycast also supports HLE BIOS functionality, while a Dreamcast BIOS is described as optional. Users should note that games are not included and must provide their own legally obtained game files.
Its main distinction is breadth within this category. Alongside Dreamcast emulation, Flycast covers Naomi, Naomi 2, Atomiswave, and System SP, while offering modern rendering options through OpenGL and Vulkan, plus high-definition output and custom texture packs. That combination suits users who want Dreamcast and arcade coverage in one emulator, particularly those interested in networking or RetroAchievements. It is less suitable for anyone looking for included game content or AI-assisted features. Choose Flycast for broad, free, open-source emulation across its supported platforms; consider an alternative if your priority is a bundled game library or a product with AI features.
