VZEM SDL

How to use:

1. Open a command prompt
2. Navigate to the directory of the executable
3. Run the executable testc.exe
4. The SDL2.dll must exist in the same directory as the exe
5. The directory must be writable as it will try to create vzem.cfg (default configuration options)

To map a disk image, type "testc -d blank.dsk"
To map a snapshot, type "testc -f galaxon.vz"

Known Issues:

1. The keyboard is very "bouncy". Pressing a key once will often register twice. Doesn't work well in games
2. The sound is not perfect, there is some crackle


To Do:

1. Replace the SDL_PollEvents with a different handler that is more effective for the keyboard
2. Add a menu option to allow loading/saving 
3. Improve the sound emulation
4. Add joystick support
5. Compile for Android and Raspberry Pi!
