crater

crater is an emulator for the Sega Game Gear, written in C.

Why?

While the internet is full of emulators for retro game systems, writing one is nevertheless a fun learning project.

Crater is named after 31 Crateris, a star that was – for a short time in 1974 – misidentified as a moon of Mercury. Mercury was Sega’s codename for the Game Gear during development.

Installing

Only OS X and Linux are tested. You’ll need a decent compiler that supports C11 (gcc, clang) and SDL 2. Using Homebrew, you can brew install sdl2; using apt, you can apt-get install libsdl2-dev.

Run make and then ./crater. To build the development version with debug symbols (they can exist simultaneously), run make DEBUG=1 and then ./crater-dev.
