A chip 8 emulator using C# and SFML.

Compiling

Currently, until I figured out how to fix it, you must create a new C# Core 3.1 console project, and import these files into it to compile.
This also requires using NuGet Package Manager to install the requirements to that project (which should only be SFML.NET v2.5 from Laurent Gomila)

Loading a ROM

place the .ch8 file in the same folder as your .exe
Change line 185 in Emu.cs:

string romName = "romName.ch8";

Recompile and run the .exe

Controls

Chip8:

keyboard - chip8 keypad  
1 2 3 4  - 1 2 3 C  
q w e r  - 4 5 6 D  
a s d f  - 7 8 9 E  
z x c v  - A 0 B F

Note that these can (and usually should) be held down.

Emulator specific:
PGUP, PGDN - scroll the RAM Viewer up or down respectively (per press, holding wont work)
F4 - Exit the emulator
F12- toggle the RAM viewer
P - pause the emulator. This literally just prevents cpu.EmulatorCycle() from getting called,
and any messages that are pending from the CPU will NOT be displayed to the console, and
the soundTimer will not be checked. Press again to unpause.
WARNING: the way this is currently implemented, this should cause a sound that's played
to play again after unpausing, if soundTimer was > 0 when pausing.

Current Version

Implemented a Dictionary lookup table for instructions.
Bye bye nasty switch...case nest.

Known issues:
Collision is wonky on breakout (1979 version), the ball will sometimes collide with blocks that
have been removed and put blocks in their place.
