 	1 - RESUME: If you pressed ON to stop C8SALT mid-execution and you haven't cleared the graph screen, you can select this option to pick up where you left off.
 	2 - LOAD FROM LROM: Loads the rom data stored in ROM. For info on converting CHIP-8 software for use with C8SALT, see ROM CONVERSION INSTRUCTIONS.
 	3 - SETTINGS: From here, you can enable and disable HLE Text Rendering (0 = on, 1 = off) as well as decide the behavior of FX55/65 (0 = Do not increment I (SCHIP style), 1 = Increment I (VIP/Octo style)), and set the shift quirk for 8XY6/8XYE (0 = SCHIP style (default), 1 = VIP/Octo style).

  WARNING: IF YOU HAVE XLib OR CELTIC III INSTALLED, YOU MUST DISABLE THEM TO RUN C8SALT!
  This is because C8SALT uses the Real( command as part of its memory decompression routine, a command which XLib uses for its functions.
