CHIP-8 interpreter
If you don't have a version of clang that supports C++20, edit the Makefile and replace CXX = clang++ with your favorite C++20 compiler. You'll also need to ensure that SDL2 is installed. Then type make.
Play a CHIP-8 rom with ./chip8em romfile. Sound is not yet supported.
The timing is not yet accurate, but screen ghosting is emulated in order to reduce flicker on certain roms.
