C8 is a minimal Chip8 emulator written in C99. It's specification was based off of this pdf. The emulator was written in a day and tries to be as close to the specification as possible. The actual emulator is located in 2 files (src/chip.h & src/chip.c) and is designed to be modular in design and can easily be reused in another project with minor modifications.
Simply run make to compile using the CLang compiler.
make clean && make
or you can use a different C compiler by specifying CC, eg. to use the GNU C compiler
make CC=gcc
the output binary will be located at bin/c8
Pass the rom as the only argument to the binary, eg. to run the maze rom do
./bin/c8 roms/maze.ch8
The controls are mapped to the keyboard, here is a side by side for comparison
