The app uses an original engine with high-quality rendering and graphics enhancements. Save states include previews, while screenshots and speed controls cover slow motion or fast forward from x0.25 to x16. A virtual on-screen keypad has customizable keys and layout, plus turbo buttons. Bluetooth and MOGA controllers are supported. Dropbox support requires John DataSync. The app contains ads, with an in-app purchase option to remove them. Google Play reports no data collected or shared with third parties, while the maker’s privacy policy says Google Play Services and AdMob may collect information used to identify users.

Snes9x is freeware for playing most games made for the Super Nintendo and Super Famicom systems. Desktop builds are listed for Windows, Linux, and macOS, with additional libretro core builds for Android, Emscripten, Wii, Switch, GameCube, and PSP. Running games requires SNES ROM images. Snes9x can save game state to freeze files and game data to SRAM files. Windows documentation describes Game Genie and Pro-Action Replay cheat formats, a cheat search feature, and recording gameplay actions for later playback. Netplay is documented for as many as five players, but the project notes that it has not been maintained or tested in a long time and might be broken. The Unix documentation says the emulator does not reproduce exact sub-cycle timing between major system components, so games with strict timing needs may not run. The project lists the software as free, with a plan price of free. Its listed platforms include Android, Linux, macOS, and Windows.
