Manic EMU vs XRoar

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.

XRoar is a free emulator for Dragon, Tandy Colour Computer, Tandy MC-10, and related 8-bit systems. Supported machines include Dragon 32/64/200-E, Tandy CoCo 1/2/3, MC-10, and Matra & Hachette Alice 4K. It runs on Android, Linux, macOS, and Windows, with XRoar Online available in a browser. The emulator reads and writes cassette, floppy disk, and block-device images, and supports machine snapshots. Emulated hardware includes floppy controllers, sound cartridges, Glenside IDE, and several RAM expansions. Video options include PAL or NTSC emulation and composite video simulation, with multiple sound drivers. A GDB remote target supports interactive debugging, though 6803 debugging is not implemented. The Becker port can communicate with pyDriveWire or Drivewire 4. In the browser version, users can fetch cassette, floppy, and hard disk images from the web or upload local files, but its sandbox keeps accessed files temporarily in memory rather than working transparently with local files. Firmware ROM images are required for useful emulation, and floppy write-back is enabled by default. XRoar is GPL version 3 or later software and comes without warranty.
