  - All other code is licensed GPL3.

* Requirements
  - SDL2 development libraries need to be installed.
  
* Installation
  - Run make, then copy the bsx executable whereever you want it.

* Usage
  - bsx path_to_rom_file

* Status
** What's done
  1) 65C816 emulation via lib65816.
  2) Selected 65C265 features.  (Can be disabled by undefining CPU65265 in opcodes.h.)
    - 65C265 Vectors are implemented.  (COP, ABORT, NMI, IRQ)
    - Added some 65C265-specific IRQ sources and vectors: IRQT5, IRNE64.
  3) VERA emulation via code extracted from X16 emulator.
  4) Loading of selected BIOS ROM.
** What's not done (i.e. TODO List)
  1) System timing.  Emulation always runs flat out instead at stable 8 Mhz.
  2) Clean up dispatch loop in dispatch.c for easier maintenance.
  3) Keyboard emulation.
  4) Timer emulation.  (Start with timer #5)
  5) SD Card emulation.
  6) Audio emulation.
  7) SNES controller emulation.
