CHIP8 Emulator. Available as a no_std lib which makes no assumptions over the system. The examples/ folder show many environments that this library can be used.

Run examples with cargo run -p <example> <filename>:

• <filename> - needs to be the path to a valid chip8 program
  • you can use the files at test_files/

• cargo run -p sdl <filename> - will open a window in your desktop
• make serve-wasm - will open a page in your browser

Mind that flickering is actually historically accurate for chip8 programs!

Some functions return u32 to return a possible error.

• If the first bit is positive, this is an error
• All the other bits are information
  • the lower bits of the first u16 is used to indicate the type of error (starting from 1)
  • the second u16 contain error data (if there is any)

The match statements at error.rs should be clear on these mappings
