Our verdict on Flycast

Flycast is a free, open-source emulator for Sega Dreamcast, Naomi, Naomi 2, and Atomiswave games. It runs across Windows, macOS, Linux, and Android, making it suitable for players who want one Sega-focused emulator across desktop and mobile platforms. The project is particularly well matched to Dreamcast and Sega arcade multiplayer, while its focused system coverage makes it less suitable for anyone seeking a broad emulator for unrelated console families.

Multiplayer is one of Flycast’s clearest differentiators. Its netplay options include peer-to-peer sessions with match codes and relay-server multiplayer sessions. The ecosystem also connects with Fightcade and Arkadyzja, giving players integrations aimed at Sega arcade and online play. These options make Flycast more than a single-player emulation tool, although buyers should expect multiplayer to involve choosing between different session types rather than relying on one universal workflow.

For visual customization, Flycast includes texture upscaling, widescreen and super-widescreen rendering, custom texture support, and adjustable rendering resolution. Save states add convenience for single-player sessions. The software is distributed under the GNU General Public License version 2.0, and its open-source model applies across the listed desktop and Android builds. Choose Flycast if Dreamcast, Naomi, Naomi 2, or Atomiswave support, visual enhancements, and Sega-focused multiplayer are the priorities. Choose another emulator if you need coverage beyond these systems or a product centered on broader platform support.
