Yet Another Chip-8 Emulator
This is currently a work in progress, with basic input and no sound support at the moment.
Built with OpenGL.
Yache uses CMake, so it should quite simple to build. The only dependencies are OpenGL and GLFW.
mkdir build
cd build
cmake ..
make./yache [options...] [file]For example using the PONG rom in the roms folder
./yache ../roms/PONG
| Option | Functionality |
|---|---|
| -d | Runs the game with the debugger |
| -f [frequency] | Sets CPU frequency |
| -s | Enables the shift quirk |
| -l | Enables the load store quirk |
Exit the program with the ESC key.
The keymap is currently hard-coded with following values:

| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| A | 4 |
| 4 | Q |
| 5 | W |
| 6 | E |

| 7 | A |
| 8 | S |
| 9 | D |
