* DONE add 65c265 compatibility
** DONE Change hard coded vectors to defined ones based on tables below.
** DONE Change references to '260' to '262'
** DONE Change references to '1300' to '1310'
** DONE Add '0,0,' to cpu_cycle_table (5 places?)
** DONE Add 'irne64' flag (like irq flag) and appropriate code in dispatch.c
  -> cpu_irne64   CPU_addIrne64()/CPU_clearIrne64
** DONE Add 'irqt5' flag and appropriate code in dispatch.c
  -> cpu_irqt5    CPU_addIrqt5()/CPU_clearIrqt5

* TODO Need a Vera demo with new kernel code
* TODO address timing - bsx just runs flat out right now, want stable 8 Mhz.
  - instrumentation: how fast are we going?
* TODO Rename sdl_events.c/sdl_events.h 
* TODO Keyboard Device.
** TODO 1) Create a new Keyboard device.
  - base this on bexemu/keyboard.c
  - takes 80 bytes in memory (might want to cut this down)
** TODO 2) Patch the Keyboard device into main.c (mem read/write)
  - maybe at $DF20-$DF6F
* TODO SDL_Event logic
  - update sdl_events.c logic to process keyboard events and put them info memory.
* TODO Possibly rewrite dispatch loop to be more readable.
  - we don't *have* to be as general as the library intends.
* TODO Add more hardware to emulation.
** TODO 65C816 Timer(s) - Start with Timer #5 for now.
  - includes interrupt processing.
