a first-pass at a Chip-8 emulated 'virtual' computer system (in C# and MonoGame)

Test roms can be found at the links below.

The keypad is currently hardcoded as

1  2  3  4
Q  W  E  R
A  S  D  F
Z  X  C  V

The emulator passes all of the standard 'tests' now, but it fails on the 'oob' out of bounds test rom.
