Azahar vs BlastEm

Azahar is a free, open-source emulator for Nintendo 3DS games, with standalone applications for Windows, macOS, Linux and Android. It is intended to let 3DS owners use their game libraries with options such as higher resolutions, modern controllers and save states. The project also serves homebrew debugging, research and preservation of the 3DS ecosystem. Community contributors continue work associated with Citra. Libretro cores allow use with RetroArch and similar frontends, including on iOS and tvOS, but Azahar’s FAQ says native iOS support is not planned for the foreseeable future and points users to an iOS build of the original Citra instead. Android requires version 10.0 or later on a 64-bit device. A per-game compatibility tracker provides reports, though the FAQ warns that these may be outdated. The mobile app privacy policy says registration is not required and the app does not collect information. Azahar states that it is not affiliated with or endorsed by Nintendo.

BlastEm is a free, open-source emulator for Sega's 16-bit and 8-bit consoles. It supports Genesis/Mega Drive, Sega CD, 32X, Master System, Game Gear, SG-1000, SC-3000, Sega Pico, and Yamaha Copera. Downloads are listed for Linux, macOS, and Windows, with an experimental web version. Gameplay features include save states, cartridge save RAM and EEPROM support, turbo and slow modes, controller input, and VGM logging. Its integrated debugger can inspect and modify state, set conditional breakpoints, run scripts, and show visual VDP tools. Developers can use the GDB remote debug protocol for source-level debugging of SGDK and other C or C++ projects. The maker describes it as fast enough for older PCs and accurate enough for demanding demos. Most Sega CD and 32X games are playable, but compatibility is not perfect. Yamaha Copera emulation is incomplete: games generally lack music, though Copera-specific ADPCM samples play. The listed macOS download is x86-64 and not notarized; the page directs ARM users to Homebrew.
