Manic EMU vs Snes9x

Manic EMU is a free retro game emulator for iPhone and iPad, supporting more than 30 classic platforms across consoles, arcade, DOS, Symbian, and J2ME. It includes save states, auto-saves, fast-forward, cheats, shortcuts, filters, screenshots, and custom skins. Cloud import works with Google Drive, Dropbox, OneDrive, Baidu, Aliyun, WebDAV, and SMB. The project says iCloud sync keeps games, saves, and settings encrypted in the cloud across devices. Manic EMU integrates RetroAchievements and supports local multiplayer and Netplay on eligible Libretro cores. The free App Store build limits fast-forward to 2×, save states and cheat codes to three each, and controllers to one player. Premium plans cost $0.99 a month, $4.99 a year, or 9.99 USD once for lifetime access, and include higher fast-forward speeds, more save states and cheat slots, and extra controller players. A free sideload build includes premium play features but does not provide iCloud save sync. The app does not include ROMs, BIOS files, or game data.

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.
