This is a simple Chip 8 Emulator created in rust. It utilized multithreading to split the emulators in to two distinct processes defined by emulator functions: run_next_instr() and extract_timers(). The former runs through a single instruction provided by the rom file, altering the Emulator struct as needed.

The latter simply extracts the references to the two timers stored in the object (both of type Arc<Mutex>) so that they can be decremented in the parallel thread. Said thread is scoped to avoid the timers' parent object being destroyed during.

This program is fairly simple to run, provided you have the cargo and rustc installed on your machine. Please note that this program has only been tested on Windows, further support is upcoming. Now the process to run it is simply running:

cargo run

within the project root directory and enter any other font you have installed on your machine. If not, don't worry, a default comes pre-packaged. After which you simply enter the name of the game you wish to play and the appropriate window will open.
