crater vs Manic EMU

crater is a free Sega Game Gear emulator written in C, with a Z80 assembler and disassembler included. Games can be loaded from the roms directory or from a command-line path. Display controls include fullscreen mode, integer scaling in a window, and an option to force square pixels. Keyboard and joystick or controller input are supported; SDL controller mappings can be defined in gamecontrollerdb.txt. Compatible games can save cartridge RAM to a .sav file, with custom save locations or saving disabled. Save states and custom keyboard mappings are not supported. The assembler converts Z80 source into a Game Gear ROM image and is described as complete. The disassembler attempts to produce assembly but cannot distinguish code from data. Most games are described as playable with minor bugs, while audio, some uncommon CPU instructions, and advanced graphics features are missing. Building requires a modern C11 compiler and SDL 2; OS X and Linux are the tested systems.

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.
