A CHIP-8 emulator/interpreter written in C++. Written following this tutorial, and uses some of its opcode implementations. Uses SFML for graphics and input. Audio isn't really implemented yet; just prints "beep."

Usage: ./chip8 /path/to/rom

Currently won't respond to pressing "close" on the window. Quit it from the terminal.

roms/c8asm is a really basic assembler. You still have to write the opcodes in hex but it supports comments (with a semicolon) and it will automatically insert the address of certain parts of code. Example:

A _sprite ; load address of the sprite into I
D0 08 ; draw 8-row sprite at (V0, V0) (V0 is 0 as we haven't changed it)

; infinite loop
_loop: ; marks this code as _loop (marks must start with _)
1 _loop ; jump to _loop

_sprite: ; just a box with a circle inside
FF 81 99 BD BD 99 81 FF

Assemble it with ./c8asm /path/to/assembly.c8s /path/to/rom.bin

On Linux, if you have SFML installed, you should be able to just run make. If you have SFML in a non-standard path you might have to change some linker flags. See https://www.sfml-dev.org/tutorials/2.5/start-linux.php.

It ought to run on macOS without too much pain if you have SFML. Windows might be trickier.

• array of function pointers instead of massive switch statement
• actual audio support
• test all the opcodes
• SUPER CHIP-8 opcodes
