Flycast vs Nitrocast

Flycast is a free emulator for Sega Dreamcast, Naomi, Naomi 2, and Atomiswave. Its Android listing says it runs most Dreamcast games, including Windows CE titles, and arcade games for Naomi, Naomi 2, Atomiswave, and System SP. Graphics options include OpenGL and Vulkan, high-definition and widescreen play, and custom high-definition texture packs. The Android listing specifies 10 save-state slots and names RetroAchievements, modem and LAN adapter emulation, and Power Smash online support in update notes. The project offers regular master builds, experimental nightly development builds, and versioned stable releases. The builds page describes master as relatively stable and cautions that other branches may be unstable, crash, or fail to run. Flycast is available for Android, Linux, macOS, and Windows, with controller support and online multiplayer listed. Game files are not included and must be owned by the user. The repository identifies the license as GPL-2.0.

Nitrocast is a free Linux Dreamcast emulator aimed primarily at homebrew development. It began as a fork of lxdream and later became a separate project. The interface uses GTK3, and the build system is Meson. Nitrocast retains OpenGL and GTK video drivers. Developer-oriented features include mounting folders at /pc and exiting with .elf return codes. The project README describes SH4 emulation as very accurate while noting that PVR emulation is lacking. A runtime flag, --ram-size, accepts 16 or 32 to emulate the Dreamcast 32MB RAM modification. Build instructions cover cloning the GitLab repository, configuring and compiling with Meson, and running the nitrocast executable. The project was created on April 26, 2019. Its project pages provide no pricing plans beyond the listed free status, and no integrations, support terms, or security and compliance claims. It is available for Linux; no other platform is listed.
