Azahar vs Play!

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 A per-game compatibility tracker provides reports, though the FAQ warns that these may be outdated.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.

Play! is a free, open-source emulator for PlayStation 2 games, with builds for Windows, macOS, Linux, Android, and iOS, plus an experimental browser port. Its high-level emulation means a BIOS is not required, and the project says users do not need custom settings to fix specific games. Games can be played by inserting a disc; desktop builds also offer command-line options for disc images, ELF files, arcade games, save-state slots, and fullscreen mode. The Play!.js browser version supports ISO, CSO, CHD, ISZ, BIN, and ELF files, but is not intended to run every game supported by desktop and mobile builds. Play! has preliminary support for Namco System 246 and 256 arcade games; release notes described 246 support as desktop-only. A compatibility tracker lists game statuses from Nothing to Playable. On iOS, playing requires JIT code generation, with device, jailbreak, or alternative JIT requirements documented by the project. Automatic JIT activation through AltServer requires it to run on the same network as the iOS device.
