= OVERVIEW =

The Synacor Challenge is a fun programming exercise with a number of puzzles
built into it. You can find more details about it here:
https://challenge.synacor.com/

The first puzzle is writing an interpreter for their custom ISA. This is a
simulator for that custom CPU. The CPU is quite basic: it's 16-bit with only
8 registers and a limited set of instructions. This means the port will never
grow new features. See README.arch-spec for more details.

Implementing it here ends up being quite useful: it acts as a simple constrained
"real world" example for people who want to implement a new simulator for their
own architecture. We demonstrate all the basic fundamentals (registers, memory,
branches, and tracing) that all ports should have.
