## About
A [CHIP-8/SUPER CHIP](https://en.wikipedia.org/wiki/CHIP-8) emulator library written in C. Most games should work but there might be some exceptions. Use at your own risk.
## Usage
Please see example_sdl2.c for an example SDL2 client.
API should be quite simple and self-descriptive, here's how a theoretical client might look like:
```c
chip8_t *ch8 = chip8_make();
if (ch8 == NULL) {
goto end;
}
bool ok = chip8_load_program(ch8, program, program_size);
if (!ok) {
goto end;
}
while (true) {
chip8_keyboard_input_t input = {};
get_input(&input);
int num_ticks = chip8_is_super(ch8) ? 16 : 8;
for (int i = 0; i < num_ticks; i++) {
ok = chip8_cpu_tick(ch8, &input);
if (!ok) {
goto end;
}
}
if (chip8_should_beep(ch8)) {
beep();
}
for (int y = 0; y < chip8_get_height(ch8); y++) {
for (int x = 0; x < chip8_get_width(ch8); x++) {
if (chip8_get_pixel(ch8, x, y)) {
draw_pixel(x, y);
}
}
}
sleep_ms(16);
}
end:
chip8_destroy(ch8);
```
