This is a Chip8 emulator (interpreter technically) developed with c and the SDL2 library. This emulator does not support audio at this time.
To test the emulator, use your system's c compiler and ensure that SDL2 is installed and that the compiler knows where to find the headers / library files that correspond to the required SDL2 functionality.
Compiling and executing the emulator is as simple as entering
the following commands within the repo's src directory:
sherbs@nostromo -> src gcc chip8_util.c chip8.c main.c -lSDL2 -o chip8
sherbs@nostromo -> src ./chip8 ../roms/INVADERS
Some of the more popular / older references may not describe certain functionality well or there are minor discrepancies in the details. The following references were really helpful in explaining everything, including the multiple ways certain ambiguous instructions might be implemented.
- Tobias Langhoff's guide is a well-written and detailed guide that leaves the code out. Really helpful for learning about the system without getting the actual implementation spoiled for you
- mattmik Mastering Chip8 also does a great job with explaining the overall functionality of the chip8 instructions without giving the code away
- r/EmuDev and its Discord, which is free to join has a huge community of emulator devs who are open to helping out.
